1.1.5 Jumper Options

The AMC.0-LED provides several jumper configuration options for features. By default all jumpers are off. Jumper locations and descriptions are provided in Chapter 3.

1.2 Unpacking

Check the shipping carton for damage. If the shipping carton or contents are damaged, notify the carrier and Sun. Retain the shipping carton and packing material for inspection by the carrier. Obtain authorization before returning any product to Sun. Refer to the Sun Netra CP3240 Advanced Mezzanine Card Getting Started Guide (820-7260) for return instructions.

Caution - This board must be protected from static discharge and physical shock. Never remove any of the socketed parts except at a static-free workstation. Use the antistatic bag shipped with the product to handle the board. Wear a wrist strap grounded through one of the system's ESD ground jacks when installing or servicing system components.

1.3 Handling AMC.0-LEDs

Caution - The system is sensitive to static electricity. To prevent damage to the assembly, always connect an antistatic wrist strap between you and the system.

Caution - Do not flex the AMC.0-LEDs; the surface-mounted components can break if the AMC.0-LED is bent.

To minimize the amount of AMC.0-LED flexing, observe the following precautions:

When removing a AMC.0-LED from an electrostatic discharge bag, keep it vertical until you place the AMC.0-LED on the electrostatic discharge mat.

Do not place a AMC.0-LED on a hard surface. Use a cushioned antistatic mat. The AMC.0-LED connectors and components have very thin pins that bend easily.

Be careful of small parts located on the component side of a AMC.0-LED.

Do not use an oscilloscope probe on the components. The soldered pins are easily damaged or shorted by the probe point.

Transport a AMC.0-LED in an antistatic bag.

1.4 AMC.0-LED Faceplate

The following shows the faceplate of the Sun Netra CP3240 AMC.0-LED. This AMC.0-LED must be paired with a Netra CP3240 switch.

FIGURE 1-1 AMC.0-LED Faceplate

This figure shows the AMC.0-LED faceplate.

1.5 LEDs

The tables in this section give status information for the LEDs on the AMC.0-LED.

The following table describes the LEDs defined by ATCA to monitor board status.

TABLE 1-1 ATCA Board Status LEDs
LED	Color	Normal Operation	Description
OOS	Red	Off	Out of service. This LED lights on a critical AMC.0-LED error, indicating that the board should be removed.
OK	Green	On	This LED is lit when the AMC.0-LED is booted and switching.
A	Amber	Off	Minor Error/User Defined. This LED can be customized using software applications.

Note that the OOS LED will be lit when the board is powered yet not booted. This includes all hot-swap states M1 through M3. It will remain on until the IPMI software has received the E-Keying signal from the shelf manager.

The following table shows the different states of the Hot-Swap LED.

TABLE 1-2 Hot-Swap LED States
Order	Visible State	State	Description
1	Solid	M1 FRU Inactive	The Intelligent Platform Management Interface (IPMI) microcontroller is booted, but the payload is not. The bottom latch is not fully closed.
2	Blinking (from solid)	M2 Activation Request	The IPMI microcontroller has requested permission to boot the payload from the shelf management controller.
3	Off	M3-M4 Active	The IPMI microcontroller has received permission to boot the payload, and has done so. This should be the state under normal operation.
4	Blinking (from off)	M5-M6 Deactivation Request	The IPMI microcontroller has requested permission to shut down the payload. Opening the bottom latch activates this state.

Note - A board should be hot-swapped only when the LED is solid blue.

1.6 Removing and Installing AMC.0-LEDs

This section describes how to remove and install AMC.0-LEDs.

1.6.1 Removing an AMC.0-LED

If you want to remove only an AMC.0-LED from a Netra CP3240 switch, use the following instructions.

If you want to remove the switch with the AMC.0-LED installed, see Section 1.6.2, Removing a Switch and AMC.0-LED.

1. Shut down the payload OS.

If you fail to do this before pulling the AMC.0-LED’s hotswap latch, the OS might panic.

2. At the front of the Netra CP3240 switch, locate the AMC.0-LED you want to remove.

3. Initiate the hot-swap deactivation sequence by pulling the injector/ejector latch out half way (FIGURE 1-2).

The Hot-Swap LED starts blinking. Wait until the LED is solid blue.

4. When the hot-swap LED is solid blue, pull the injector/ejector latch out completely (FIGURE 1-2).

FIGURE 1-2 Deactivating the AMC.0-LED

This figure shows how to deactivate the AMC.0-LED.

Figure Legend
1	Fully In (IN) When IN, the module communicates to the Shelf Manager that the module is not in the Hotswap state, and the Shelf Manager communicates with the MMC. This position is for normal operation.
2	Half Way (HW) When in the HW position, the hotswap sequence is initiated. The MMC sends a hotswap event to the Shelf Manager.
3	Out (OUT) When OUT, the latching mechanism is released and the module can be extracted. Wait for the Hot-Swap LED to stop blinking before pulling the latch all the way out.

5. Remove the AMC.0-LED as shown in the following figure.

FIGURE 1-3 Removing the AMC.0-LED

This figure shows how to remove the AMC.0-LED from the switch.

Caution - Failure to fill all sites with AMC.0-LEDs or cover with filler panels can negatively impact the cooling of the system.

6. Replace the AMC.0-LED with another AMC.0-LED (FIGURE 1-7) or a filler panel.

Note - Be sure to follow handling instructions. See Section 1.3, Handling AMC.0-LEDs.

1.6.2 Removing a Switch and AMC.0-LED

This figure shows how to disengange the injector/ejector latch on the switch.

4. Disconnect all cables connected to the switch.

5. Loosen the two board retention screws that fasten the board to the enclosure.

6. Open the ejectors fully, rotating the handles outward until the board disengages from the midplane.

7. Slide the board evenly out of the enclosure.

Caution - Failure to cover all open sites with filler panels can negatively impact the cooling of the system.

8. Either replace the switch or install a filler panel:

If you are going to replace the switch, refer to the Sun Netra CP3240 Switch Installation Guide (820-3251) for instructions.

If you are not going to replace the switch, install a filler panel to maintain the shielding and cooling performance of the enclosure.

Note - When a switch is removed from the site, and the system is running with only a single remaining switch, you do not have redundancy for that component. Both switches must be installed and running to have redundancy for that component.

1.6.3 Installing an AMC.0-LED

Following are the instructions for installing an AMC.0-LED. For instructions on installing switch and RTM sets, refer to the Sun Netra CP3240 Switch Installation Guide (820-3251).

1. At the front of the Netra CP3240 switch, locate the AMC site where you want to install the AMC.0-LED.

2. Remove the filler panel, if necessary.

3. Obtain the AMC.0-LED card from the ship kit.

Note - Follow unpacking and handling instructions in Section 1.2, Unpacking and Section 1.3, Handling AMC.0-LEDs.

4. Perform any card-specific hardware procedures, if necessary.

5. Prepare the AMC.0-LED by opening its injector/ejector latches.

FIGURE 1-6 Opening the Injector/Ejector Latches

This figure shows how to open the AMC.0-LED injector/ejector latches.

Figure Legend
1	Fully In (IN) When IN, the module communicates to the Shelf Manager that the module is not in the Hotswap state, and the Shelf Manager communicates with the MMC. This position is for normal operation.
2	Half Way (HW) When in the HW position, the hotswap sequence is initiated. The MMC sends a hotswap event to the Shelf Manager.
3	Out (OUT) When OUT, the latching mechanism is released and the module can be extracted. Wait for the Hot-Swap LED to stop blinking before pulling the latch all the way out.

6. Carefully align the edges of the board with the guides in the appropriate site.

It might be helpful to look into the enclosure to verify correct alignment of the rails in the guides.

Caution - Do not force the AMC.0-LED into the site. If it does not fit properly, check to ensure that you have the correct matching AMC.0-LED for the switch.

7. Keeping the board aligned in the guides, slide the board in by pressing on the AMC.0-LED faceplate until the AMC.0-LED faceplate is flush with the Netra CP3240 switch faceplate.

FIGURE 1-7 Inserting the AMC

This figure shows how to insert the AMC.0-LED into the switch.

8. Push the ejector latch in fully.

If the system power is on and the AMC.0-LED is installed properly, the AMC.0-LED board Hot-Swap LED lights up. The Hot-Swap LED blinks for several seconds, then goes off.

If the Hot-Swap LED does not go off after several seconds, push firmly on the injector/ejector handles to ensure that they are pushed in all the way.

Caution - Failure to fill all sites with AMC.0-LEDs or cover with filler panels can negatively impact the cooling of the system.
