Powering the Server On and Off

This chapter gives instructions on powering the Netra CT server on and off.

Connecting a Terminal Console to the Server

Powering On the Server

Powering Off the Server

Note - Whenever you reboot or power your server on and off, the hot swap states revert back to the default full hot swap state for all I/O slots. If you want basic hot swap on an I/O slot, you must manually reset the I/O slot to basic hot swap after rebooting or powering your server on and off.

Note - You can also power the Netra CT server on and off through the alarm card using software commands. Refer to the Netra CT Server System Administration Manual for more information.

Connecting a Terminal Console to the Server

One way to power on and off your server is to log in to the server either remotely, where you would log in to the Netra CT server as root through another server on the network, or directly, where you would connect a terminal console directly to your Netra CT server. A terminal console can be an ASCII terminal, workstation, or PC laptop.

For a direct login, the connection you use varies depending on the Netra CT server model you have, the type of terminal console you are using, and the card that you are connecting to:

If you are using an ASCII terminal to power on and off the Netra CT server, go to To Use an ASCII Terminal.

If you are using a Solaris workstation to power on and off the Netra CT server, go to To Use a Solaris Workstation.

If you are using a PC laptop to power on and off the Netra CT server, go to To Use a PC Laptop.

To Use an ASCII Terminal

1. Get the appropriate cable(s) and adapter(s) and make the necessary connections.

You may need one or more cables and adapters in order to connect the ASCII terminal to the server. The cables and adapters you need varies, depending on the model server you have and the card that you are connecting to.

If you are connecting an ASCII terminal to a CPU or CPU transition card, use the information in TABLE 7-1 to make the necessary connections.

If you are connecting an ASCII terminal to an alarm card or alarm rear transition card, use the information in TABLE 7-2 to make the necessary connections.

Powering On the Server

Note - You must have the host CPU card, alarm card and system controller board installed in the Netra CT server before you can power it on; the server will not power on properly if all three of these components are not installed. Once the system is powered on and running, then you can hot-swap any of the three components as documented in the Netra CT Server Service Manual. Also, do not reboot the server if the alarm is in the process of resetting.

1. Verify that the power supply locking mechanism(s) on the server you are about to power on are in the locked (), or down, positions (FIGURE 7-1).

Make sure you lock both power supplies if you are powering on a Netra CT 810 server.

FIGURE 7-1 Locating the Power Supply Locking Mechanism on the Netra CT 810 Server

Figure showing the location of the power supply locking mechanism on the Netra CT 810 server.

When the power supply locking mechanism is locked, the green LED on the power suppl(ies) flash, indicating that the power suppl(ies) are powered on, but the server has not been powered on yet. Also, the PDU LEDs on the system status panel should be in this state:

Green LED () is ON

Amber LED () is OFF

This tells you that the power supply locking mechanism(s) are in the locked (down) position and the power distribution unit(s) are receiving power and functioning properly.

2. Locate the system status panel.

The location of the system status panel in the Netra CT 810 server and Netra CT 410 server is illustrated in FIGURE 7-2.

FIGURE 7-2 System Status Panel Locations

Figure showing the location of the system status panels on the Netra CT servers.

3. Locate the system power button on the system status panel and press the system power button to power on the server.

FIGURE 7-3 shows the system power button location for the Netra CT 810 server, and FIGURE 7-4 shows the system power button location for the Netra CT 410 server.

When you first power-on the Netra CT server, some or all of the green Power LEDs on the system status panel flash on and off for several moments.

4. Verify that the system power LED on the system status panel is on, indicating that the system is completely powered on.

FIGURE 7-3 shows the system power LED location for the Netra CT 810 server, and FIGURE 7-4 shows the system power LED location for the Netra CT 410 server.

5. Verify that the green power () LED on the power supplies are on, indicating that they are powered on and functioning properly.

6. If you have a Netra CT 410 server, connect an external DVD drive to your server.

Refer to Appendix A for more information.

7. Insert the Solaris operating environment DVD into the DVD drive.

8. Log into your server.

Refer to Connecting a Terminal Console to the Server for instructions on connecting a terminal to your server, if necessary.

9. Boot up the server through the DVD drive.

As root, enter:

# boot cdrom

Powering Off the Server

You can power off the Netra CT server one of three ways, depending on the terminal hookup and the state of the host CPU:

If you have a terminal hookup to your server and your host CPU is functioning normally, you should go through a graceful software power-down for your server. A graceful software power-down is a normal power-down using a terminal connected to your server, where you would log onto the server as root, then execute a software command to bring the server down safely. Go to To Perform a Graceful Software Power-Down for those procedures.

If you do not have a terminal hookup to your server but your CPU is functioning normally, you should go through a graceful hardware power-down for your server. For a graceful hardware power-down, you would press the system power button for less than four seconds. This will start the orderly power-down sequence in a manner that no persistent OS data structures are corrupted. In the orderly power-down, applications in service may be abnormally terminated and no further services will be invoked by the CPU. Go to To Perform a Graceful Hardware Power-Down for those procedures.

If you do not have a terminal hookup to your server and your CPU is not functioning normally, you will not be able to go through a graceful hardware power-down; you will have to go through an ungraceful hardware power-down instead. For an ungraceful hardware power-down, press the system power button for more than four seconds. This will immediately shut the system down without making any attempts to keep the persistent OS data structures from being corrupted.

To Perform a Graceful Software Power-Down

1. In preparation for bringing down the operating system and powering down the server, ensure that all significant application activity is quiesced on the server.

2. Log into your server.

Refer to Connecting a Terminal Console to the Server for more information.

3. Determine if you are at the OpenBoot (ok) prompt.

If you are at the ok prompt, go to Step 4.

If you are not at the ok prompt, at the system console, and enter:

# cd /

# shutdown -i0 -g0 -y

When the server is finished shutting down, the ok prompt is displayed.

4. At the ok prompt, enter:

ok power-off

5. Go to the front of the Netra CT server and locate the power supply unit(s).

6. Determine if the green power () LED on the power supply unit(s) are blinking.

If the green power LED on the power supply unit(s) are blinking, then the system is in standby mode. Go to Step 7.

If the green power LED on the power supply unit(s) are not blinking, then the system did not respond to the graceful power-down; you must go through an ungraceful hardware power-down instead. Press the system power button for more than four seconds. This will immediately shut the system down without making any attempts to keep the persistent OS data structures from being corrupted.

7. If you want to completely power off the Netra CT server, push the purple power supply unit locking mechanism(s) up into the unlocked () position (see FIGURE 7-1).

Note - You must unlock the locking mechanism on both power supply units on the Netra CT 810 server in order to completely power off that server.

The green power () LED(s) on the power supply unit(s) should go off (unlit), indicating that the system is now completely powered off.

To Perform a Graceful Hardware Power-Down

1. In preparation for bringing down the operating system and powering off the server, ensure that all significant application activity is quiesced on the server.

2. Go to the front of the Netra CT server and locate the system status panel.

The location of the system status panels in the Netra CT 810 server and Netra CT 410 server is illustrated in FIGURE 7-2.

3. Locate the system power button on the system status panel.

FIGURE 7-3 shows the system power button location for the Netra CT 810 server, and FIGURE 7-4 shows the system power button location for the Netra CT 410 server.

4. Press the system power button and release it to go through a graceful hardware power-down.

This will start the orderly power-down sequence in a manner that no persistent OS data structures are corrupted. In the orderly power-down, applications in service may be abnormally terminated and no further services will be invoked by the CPU. The system power LED will blink for several seconds, then it will go off.

5. Wait for several moments, then verify that the green power () LED(s) on the power supply unit(s) are blinking, indicating that the system is in the standby mode.

FIGURE 7-3 shows the system power LED location for the Netra CT 810 server, and FIGURE 7-4 shows the system power LED location for the Netra CT 410 server.

6. If you want to completely power off the Netra CT server, push the purple power supply unit locking mechanism(s) up into the unlocked () position (see FIGURE 7-1).

Note - You must unlock the locking mechanism on both power supply unit(s) on the Netra CT 810 server in order to completely power off that server.

The green power () LED(s) on the power supply unit(s) should go off (unlit), indicating that the system is now completely powered off.
