5.7 Replacing the T5520UR Server Board
The IP Network Server NSN2U uses the Intel® server board T5520UR. To replace the
server board, the following components must be removed first:
•
Both top chassis covers
• Riser card assembly and plastic guide bracket
• Processor air duct
• Any I/O expansion module or RMM GCM module
• Any cables attached to the server board
• Bridge board
• Power distribution board
In addition, you will probably want to remove the following components for reuse on
the replacement server board if it hasn’t already been populated with spare
components:
•
Heat sink(s)
• Processor(s)
• All DIMMs
• Flash memory drive, if installed
CAUTION: Before replacing any of the boards on the NSN2U server, you must first take
the server out of service, turn off all peripheral devices connected to the
server, turn off the server by pressing the power button, and unplug the power
cord(s) from the system and wall outlet.
When handling the power distribution board, observe the normal safety and ESD
precautions. See Appendix A: Safety Information for more information.
Removing the Old Server Board from the Chassis
1. Power down the server and unplug all peripheral devices and the power cable(s).
2. Remove both of the chassis covers. For instructions, see “Removing the Chassis

10. Remove the GCM4 module if installed. For information about how this card is
installed, see Section 4.10, “Installing a Remote Management Module”.
If you want to reuse components from this server board on the new replacement board,
you can remove them now or after you have removed the server board from the chassis.
