![]() |
Caution - If you are just powering on your Netra CT server, do not remove or install any cards in the system until you have verified that the system is completely powered up. Refer to Section 2.1.1, Verifying Full Power-Up for more information. |
![]() |
Caution - An energy hazard is present if any I/O slots are left uncovered. If you remove a card from an I/O slot, you must fill it with either a replacement card or a filler panel. |
Note - Consult the Netra CT Server Safety and Compliance Manual and Chapter 3 of this document for safety and board-handling information prior before performing the procedures in this chapter. |
There are three types of cards that are hot-swappable in the Netra CT server:
The procedures for removing and replacing these cards are given in Section 6.1, Main Cards.
Note that the front transition cards are only hot-swappable as long as the accompanying host CPU card has been removed first.
The procedures for removing and replacing these cards are given in Section 6.2, Front-Transition Card.
Note that the rear transition cards are only hot-swappable as long as the accompanying main card has been removed first.
The procedures for removing and replacing these cards are given in Section 6.3, Rear-Transition Cards.
This section gives procedures for the installation, removal, and replacement of the following hot-swappable cards for the front-access models of the Netra CT 410 server and Netra CT 810 server:
FIGURE 6-1 shows the locations of these cards in the Netra CT 810 server. FIGURE 6-2 shows the locations of these cards in the diskfull Netra CT 410 server, and FIGURE 6-3 shows the locations of these cards in the diskless Netra CT 410 server.
Before removing and replacing any of the main cards in your server, you must first understand all rules and restrictions involved. The following sections describe the rules and restrictions for the main cards:
Following are the rules and restrictions you must understand before hot-swapping any card in the Netra CT server:
1. You must have the host CPU card, alarm card and system controller board installed in the Netra CT server before you can hot-swap any I/O card or satellite CPU card.
2. You may not be able to perform a full hot-swap on any card if the card is in a failed condition; you must perform a basic hot-swap in this case. To determine if a card has failed, verify that these LEDs are in following states:
If the card has failed, you must manually unconfigure the card before you can hot-swap it by entering the following commands:
where ap_id is the attachment-point ID listed in the first column.
If the LED states continue to show a failed condition for the card, then you must halt the system.
3. You can only remove a card if all of these LEDs are in the following states:
Do not remove any card from the system if any of the LEDs is not in the proper state.
Following are the rules and restrictions you must understand before hot-swapping a host CPU card:
1. You must have the alarm card and system controller board installed in the Netra CT server before you can hot-swap the host CPU card.
2. When you remove a host CPU card from a server while the server is running, it will disable the CompactPCI bus, which means that the connection with all I/O cards installed in the server will be lost. Once the CompactPCI bus is disabled, MCNet will also become disabled in the system.
After you install the host CPU card back into the server, it will enable the CompactPCI bus and will attempt to connect to all occupied card slots.
Satellite CPU cards are unaffected by the disabling of the CompactPCI bus; they will continue to function as stand-alone processors when you hot-swap a host CPU card.
3. If the host CPU is at the OpenBoot prompt (the ok prompt) and you want to hot-swap the host CPU card, you must power off the host CPU slot through the alarm card.
To power off the host CPU slot in a Netra CT server, access the alarm card and, through the alarm card command line interface, enter:
Refer to the Netra CT Server System Administration Manual for more information on accessing the alarm card.
Use the poweron command to power on the host CPU card once you've installed the replacement host CPU card.
4. If you are installing a Netra CP2140 host CPU board into a Netra CT server, do not change the default SMC module switch settings on the SW0501 switches. The Netra CT server supports high availability hot swap; however, because the alarm card controls the high availability on the Netra CT server, the settings on the SW0501 switches on the Netra CP2140 host CPU card should actually be set in the default, non-high availability settings. Refer to the Netra CT Server Product Overview for more information.
Following are the rules and restrictions you must understand before hot-swapping an alarm card:
1. You must have the host CPU card and the system controller board installed in the Netra CT server before you can hot-swap the alarm card.
2. You cannot hot-swap any other component in a Netra CT server while the alarm card is being hot-swapped.
3. You cannot install any new component into a Netra CT server while the alarm card is being hot-swapped.
The individual slots in your server will be set to full hot swap by default. You can also change the slots to basic hot swap manually. Refer to Chapter 5 for more information.
Note - Do not proceed with these instructions until you have reviewed the information in Section 6.1.1, Rules and Restrictions for Hot-Swapping Main Cards. Failure to do so may result in an inadvertent system reboot or incorrect configuration information. |
1. Locate the card that you want to remove from the server.
FIGURE 6-1 shows the locations of these cards in the Netra CT 810 server. FIGURE 6-2 shows the locations of these cards in the diskfull Netra CT 410 server, and FIGURE 6-3 shows the locations of these cards in the diskless Netra CT 410 server.
2. Log into the Netra CT server.
Refer to Section 5.2.1, Logging In to the Netra CT Server, then return to this procedure.
3. Perform any necessary card-specific software commands.
4. Determine the hot swap state for the slot that holds the card you are about to remove.
To determine the current hot swap state for the slots in your server, as root, enter:
The output is similar to the following (note that the following output is for a Netra CT 810 server; the output is similar for the Netra CT 410 server):
5. Identify the attachment-point ID that corresponds to the slot where you will be removing the card.
For a Netra CT 810 server, you should get feedback similar to the following:
For a Netra CT 410 server, you should get feedback similar to the following:
The attachment-point ID is shown in the first column of the readout; for example, the attachment-point ID for slot 4 in a Netra CT 810 server would be IO-4.
6. Disconnect the card with the cfgadm (1m) utility:
where ap_id is the attachment-point ID. For example, to deactivate the card in slot 4, as root, enter:
7. If you are hot-swapping an alarm card, reset the alarm card before removing it.
Refer to the Netra CT Server System Administration Manual for more information.
8. Attach the antistatic wrist strap.
Refer to Section 1.2, Attaching the Antistatic Wrist Strap.
9. Using a No. 2 Phillips screwdriver, loosen the two captive screws inside the card's ejection levers, one on top and one on the bottom (FIGURE 6-4).
10. Unlock the ejection levers.
![]() |
Caution - Only unlock the ejection levers at this point; do not unseat the card until the LEDs on the system status panel are in the proper state. |
There are several different models of locking ejection levers, so the method you would use to unlock the ejection levers will vary depending on the model of the ejection lever used on the card; for example, one model uses red tabs at the top and bottom to unlock the card (FIGURE 6-5). Refer to the documentation that came with the card for instructions on unlocking the card.
11. Locate the LEDs on the system status panel for the card that you want to remove.
The system status panel on each server has LEDs that show the status of the card installed in each set of the slots in that particular server. FIGURE 6-6 shows the LEDs on the Netra CT 810 server and FIGURE 6-7 shows the LEDs on the Netra CT 410 server.
12. Determine if you can remove the card safely at this time.
You can remove the card only if all of these LEDs are in the following states:
For more information on all the stages and meanings of the system status panel LEDs, refer to Troubleshooting the System Using the System Status Panel. The following table gives more detailed information on the LEDs and the meanings of each of their states.
Note - If the server is set to the default full hot-swap mode, unlocking the ejection levers automatically starts the cfgadm unconfigure operation. If you decide that you do not want to remove the card, you must wait until the LEDs are in the correct state (as shown in Step 12), completely unseat the card, reseat it, then lock the ejection levers again in order to start the cfgadm configure operation. Simply locking the ejection levers after unlocking them will not start the driver attachment process. |
13. When it is safe to remove the card, disconnect any cables connected to the card.
14. Press outward on the two ejection levers on the card to unseat the card from the card cage.
15. Carefully slide the card out of the slot and place it on the electrostatic discharge mat.
If you are hot-swapping an alarm card, you may notice one thing that is unique to the alarm card. If you enter the cfgadm command after you have removed the alarm card, you will see disconnected under the Receptacle column. For all other cards, after you have removed the card, you should see empty under the Receptacle column.
16. Perform any additional card-specific hardware procedures, if necessary.
For example, you may want to remove the PMC(s) from a faulty satellite CPU or I/O card and install it on the replacement card later on. Refer to the documentation that you received with your card for more information.
17. Secure a blank filler panel over the empty I/O slots, if necessary.
If you are not going to replace the card right away, you must install a blank filler panel over the opening to ensure proper airflow in the system. The slot filler panel is secured to the card cage using two screws, one at the top of the filler panel, the other at the bottom.
18. Determine if you are removing a card from a front-access or rear-access model server.
1. Attach the antistatic wrist strap.
Refer to Section 1.2, Attaching the Antistatic Wrist Strap.
2. Locate the card slot where you will be installing the card.
FIGURE 6-1 shows the locations of these cards in the Netra CT 810 server. FIGURE 6-2 shows the locations of these cards in the diskfull Netra CT 410 server, and FIGURE 6-3 shows the locations of these cards in the diskless Netra CT 410 server.
3. Determine if you are installing a card in the front-access model or the rear-access model of the Netra CT server.
4. Remove the slot filler panel, if necessary.
The slot filler panel is secured to the card cage using two screws, one at the top of the filler panel, the other at the bottom. Store the slot filler panel in a safe place; you may have to use it again if you have to remove a card for an extended period of time.
5. Get the replacement card from the ship kit.
6. If you are installing a new alarm card, remove the blue protective film from the front of the alarm card, if necessary.
7. Perform any card-specific hardware procedures, if necessary.
For example, if you removed a PMC from a satellite CPU or I/O card, then you will want to install the PMC into the replacement satellite CPU or I/O card at this time. Refer to the documentation that you received with your satellite CPU or I/O card for more information.
8. Verify that the ejection levers on the card are unlocked.
You will not be able to install the card properly if the ejection levers are locked.
9. Keeping the card vertical, slide the card into the slot between the two guides.
The cuts in the handle of the card must align with the square cutouts in the slot. When the card is completely seated in the card cage, the two ejection levers should flip inward, and the notches in the ejection levers should fit smoothly in the rectangular cutouts in the bottom and top plates.
There are several different models of locking ejection levers, so the method you would use to lock the ejection levers will vary depending on the model of the ejection lever used on the card. Refer to the documentation that came with the card for instructions on locking the ejection levers.
11. Using a No. 2 Phillips screwdriver, tighten the two captive screws inside the card's ejection levers, one on top and one on the bottom.
Tighten the screws to a torque of 0.28 N.m (2.5 in.-lb).
12. Log into the Netra CT server.

The output is similar to the following (note that the following output is for a Netra CT 810 server; the output is similar for the Netra CT 410 server):
14. Identify the attachment-point ID that corresponds to the slot where you inserted the card.
For a Netra CT 810 server, you should get feedback similar to the following:
For a Netra CT 410 server, you should get feedback similar to the following:
The attachment-point ID is shown in the first column of the readout; for example, the attachment-point ID for slot 4 in a Netra CT 810 server would be IO-4. Note that the information for the card installed in slot 4 in the example feedback shows it as unknown (Type), disconnected (Receptacle), unconfigured (Occupant), and unknown (Condition). This confirms that the slot has been set to basic hot swap and that the card in the slot has not yet been activated.
15. Connect the card with the cfgadm dynamic reconfiguration software:
where ap_id is the attachment-point ID. For example, to connect the card in slot 4, as root, enter:
16. Activate the card with the cfgadm (1m) utility:
where ap_id is the attachment-point ID. For example, to activate the card in slot 4, as root, enter:
If you were to enter the cfgadm pci command again at this point, you should see the fields changed for the card in slot 4:
17. Locate the LEDs on the system status panel for the card that you just inserted.

The satellite CPU rear transition card set consists of two separate cards:
The satellite CPU card is installed from the front of the Netra CT server; however, no cables are connected to the satellite CPU card. It is the same satellite CPU card that is used in the front-access model of the Netra CT server.
The rear transition card extends the ports from the PMCs installed in the satellite CPU card to the PIMs installed in the satellite CPU rear transition card. The satellite CPU card must be installed in the same slot at the front of the server in order for the satellite CPU rear transition card to work. For example, if you install a satellite CPU rear transition card in I/O slot 3 at the rear of a Netra CT 810 server, you must also install the accompanying satellite CPU card in I/O slot 3 at the front of the server.
When one of the two cards fails, you may not be able to determine which of the two cards has failed. Because of this, you may want to replace both the satellite CPU card and the satellite CPU rear transition card. FIGURE 6-21 and FIGURE 6-22 give graphical representations of how the satellite CPU cards should align with the satellite CPU rear transition cards (RTCs). Note that, if you are facing the front of the server, the I/O slots read from left to right, whereas they read from right to left if you are facing the rear of the server.
The I/O rear transition card set consists of two separate cards:
The front I/O card contains the ASICs for the associated I/O card and is installed from the front of the server; however, no cables are connected to the front I/O card.
The I/O rear transition card extends the ports for a particular I/O card to the rear of the server. The I/O rear transition card and the front I/O card must be installed in the same slot at the front of the server in order for the I/O rear transition card to work. For example, if you install an I/O rear transition card in I/O slot 3 at the rear of a Netra CT 810 server, you must also install the accompanying front I/O card in I/O slot 3 at the front of the server.
When one of the two cards fails, you may not be able to determine which of the two cards has failed. Because of this, you may want to replace both the front I/O card and the I/O rear transition card.
