2. Install the I/O module.

a. Ensure that the I/O module release lever is fully extended. See Figure6-10.

b. Slide the module into the chassis until it is fully seated.

c. Close the release lever until it snaps securely into place.



3. If a daughter card(s) was included with the new I/O module, install the daughter card(s). See "Daughter Card" in "Removing and Installing Server

Module Components."



4. Reconnect any cables that must be attached to the module.

See the documentation that accompanied the I/O module for information about its cable connections.

Server Modules

Your system can include up to 10 hot-pluggable server modules. Each server module can contain up to two microprocessors, two hard drives, six memory

modules, and one daughter card.

Removing a Server Module



1. Ensure that the server module's power is off.

When a server module is powered off, its front-panel power indicator is amber. See Figure2-3.



2. Press in the release latch on the inside of the upper handle. See Figure6-11.



3. Pull out both the upper and the lower handles to eject the server module from the chassis.



4. Slide the server module out of the chassis.

Installing a Server Module

NOTE: Bays IO/1 and IO/2 accept only PowerConnect 5316M Ethernet switch modules or Gb Ethernet pass-through modules. If only one module is

used, it must be installed in bay IO/1. Bay IO/2 is for a second PowerConnect 5316M Ethernet switch module or Gb Ethernet pass-through module

for redundancy.

NOTE: The daughter card enables a server module to communicate with the corresponding connector number on its appropriate I/O module. 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).

NOTICE: If you are permanently removing the server module, install a server module blank. Operating the system for extended periods of time without

a server module blank installed can cause the system to overheat.

NOTICE: Follow this procedure carefully—it is possible to insert the server module upside-down, which may damage the chassis midplane and the

server module.
