Removing Memory Modules
CAUTION:
Only trained service technicians are authorized to remove the system cover and access any of the
components inside the system. See your Product Information Guide for complete information about safety
precautions, working inside the computer, and protecting against electrostatic discharge.
CAUTION:
The DIMMs are hot to the touch for some time after the system has been powered down. Allow time
for the DIMMs to cool before handling them. Handle the DIMMs by the card edges and avoid touching the DIMM
components.

2 Open the server module. See "Opening the Server Module" on page 75.
3 Locate the memory module sockets. See Figure 6-3.
4 Press down and out on the ejectors on each end of the socket until the memory module pops out of the
socket. See Figure 3-16.

I/O Module Daughter Card
The server module board daughter-card connectors support a variety of dual-channel I/O module
daughter cards, including a TCP/IP Offload Engine (TOE) NIC daughtercard.
• If installed, the daughter card must be used in conjunction with its appropriate back-panel I/O module
and connector number.
For example, server module number 5 must have a Fibre Channel daughter card installed to
communicate with the Fibre Channel pass-through module connector number 5 (primary and
secondary bays).
• You cannot install daughter cards of different fabric types within a system.
For more information on I/O module daughter cards, see "Guidelines for Installing Connectivity
Modules" on page 28.
