5.5.2 Replacing the SEEPROM

For the SEEPROM replacement procedure, see Section 2.5.3, Replacing the SEEPROM.


5.6 Removing and Replacing a PMC Device

A PCI mezzanine card (PMC) is a slim, modular mezzanine card that provides additional functionality to the Netra CP2500 board. The board contains one PMC slot in which you can an install optional PMC device (see FIGURE 5-8 for the location of the slot).



Note - Because an installed PMC device will block access to the memory connector's retainer clips, you need to remove the PMC device prior to removing and replacing the memory modules.



5.6.1 Removing a PMC Device

1. Remove the board from the chassis and place the board on an ESD mat (if one is available) on a suitable work area.

See Section 5.4.1, Removing the Board From the Chassis for the board removal procedure.

If an ESD mat is not available, place the card on the antistatic envelope it was originally packaged in.

2. Take antistatic precautions by attaching and electrically grounding an antistatic wrist strap.

3. Flip the board over on the ESD mat so that the board's solder-side is facing you.

You can only access the screws securing the PMC device from the solder-side of the board.

4. Using a No. 2 screwdriver, remove the four screws securing the PMC device to the board (FIGURE 5-6).

5.7 Removing and Replacing Memory Modules

The Netra CP2500 board accommodates two 184-pin, very low profile (VLP) DDR-1 SDRAM dual in-line memory modules (DIMMs). The board does not have any on-board memory, so it will not operate without installed memory modules. New Netra CP2500 boards that ship from Sun contain two preinstalled memory modules.



caution icon

Caution - The Netra CP2500 board supports memory modules sold by Sun Microsystems only. Do not install a DIMM pair sold by any other vendor or manufacturer.





Note - You must install memory DIMMs in matched pairs. For example, the board will not operate if you install one 512 Mbyte DIMM and one 1 Gbyte DIMM on the board, or if you install only one DIMM on the board.




FIGURE 5-9 Location of Memory Connectors

Figure showing the location of the memory connectors.


5.7.1 Removing DIMM Memory Modules

You might need to remove a DIMM module from the Netra CP2500 board if you are returning the DIMM module pair or the board for service, or if you are replacing a DIMM module pair with another DIMM pair purchased from Sun Microsystems.



Note - Prior to removing memory modules from the Netra CP2500 board, you will need to remove any installed PMC device. An installed PMC device might block access to the memory connector's retainer clips. For PMC device removal procedures, see Section 5.6.1, Removing a PMC Device.





Note - Safely store the original factory-shipped DIMM and related DIMM packaging. You might want to store any removed DIMM in the new DIMM packaging, or use the packaging for service.



To remove a DIMM from the Netra CP2500 board, perform the following steps:

1. Remove the board from the chassis and place the board on an ESD mat (if one is available) on a suitable work area.

See Section 5.4.1, Removing the Board From the Chassis, for the board removal procedure.

If an ESD mat is not available, place the card on the antistatic envelope it was originally packaged in.

2. Take antistatic precautions by attaching and electrically grounding an antistatic wrist strap.



caution icon

Caution - Always wear a grounded antistatic wrist strap when handling memory modules.



3. For the DIMM you want to remove, simultaneously pull both DIMM retainer clips outward from the slot.

The DIMM releases outward at an angle of about 20 degrees (see FIGURE 5-10).

4. Grasp the DIMM by the edges, and carefully pull it out of its connector (see FIGURE 5-10).

Ensure that you pull the DIMM out at an angle of about 20 degrees, or you might damage the DIMM.


FIGURE 5-10 Removing a DIMM

Figure showing the removal of a memory module.


5. Place the DIMM in an antistatic bag.

6. Repeat this procedure for the second DIMM memory module.

5.7.2 Installing Memory Modules



Note - Prior to installing memory modules on the Netra CP2500 board, you will need to first remove any installed PMC device. An installed PMC device may block access to the memory connector's retainer clips. For PMC device removal procedures, see Section 5.6.1, Removing a PMC Device.



The following procedure describes how to install memory onto the board.



caution icon

Caution - Do not remove the memory module from its antistatic container until you are ready to install it on the board. Handle the module only by its edges. Do not touch module components or metal parts. Always wear a grounded antistatic wrist strap when handling modules.



1. Place the board on an ESD mat (if one is available) on a suitable work area.

If an ESD mat is not available, place the card on the antistatic envelope it was originally packaged in.

2. Take antistatic precautions by attaching and electrically grounding an antistatic wrist strap.



caution icon

Caution - Always wear a grounded antistatic wrist strap when handling memory modules.



3. Locate the two DIMM connectors on the Netra CP2500 board.

Select the connectors where you will install the memory modules (see FIGURE 5-9). If you need to replace an existing memory module with a new module, see Section 5.7.1, Removing DIMM Memory Modules for instructions on removing the DIMM module.



caution icon

Caution - Do not install just one memory module. You must install memory in matched pairs, with each module containing the same memory capacity.



4. Carefully pull the memory connector's retainer clips open (see FIGURE 5-11).

5. Remove the DIMM from its protective packaging, holding the module only by the edges.

6. Holding the DIMM at approximately a 20-degree angle to the board, insert the bottom edge of the DIMM into the bottom of the slot connector (see FIGURE 5-11).

The socket and module are both keyed, which means the module can be installed one way only. With even pressure, push simultaneously on both upper corners of the DIMM until its bottom edge (the edge with the gold fingers) is firmly seated in the connector.


FIGURE 5-11 Installing a DIMM Into a Board Memory Connector

Figure showing how to install a memory modules.




caution icon

Caution - Evenly engage the DIMM in its slot at the 20-degree angle; uneven contact can cause shorts that will damage the Netra CP2500 board. Do not rock the DIMM into place. Ensure that all contacts engage at the same time. You feel or hear a click when the DIMM properly seats in the connector.



7. Press the top edge of the DIMM toward the board until the retainer clips click into place (see FIGURE 5-11).

The small retainer clips on each side of the DIMM slot click into place in the notches on the DIMM sides.

8. Repeat this procedure for the second DIMM memory module.



Note - If you removed a PMC device prior to removing and replacing memory modules, see Section 2.5.1, Installing an Optional PMC Device for the PMC device replacement procedure.
