Installation guidelines
Before you begin to install the Ethernet switch module in your BladeCenter unit,
read the following information:
v Become familiar with the safety and handling guidelines specified under “Safety”
on page ix and “Handling static-sensitive devices” on page 9, and read the safety
statements in BladeCenter unit option publications.
v The orange color on components and labels in your BladeCenter unit identifies
hot-swap or hot-plug components. You can install or remove hot-swap modules
while the BladeCenter unit is running. For complete details about installing or
removing a hot-swap or hot-plug component, see the detailed information in this
chapter.
v The blue color on components and labels identifies touch points where you can
grip a component, move a latch, and so on.
v You do not need to turn off the BladeCenter unit to install or replace any of the
hot-swap modules on the rear of the BladeCenter unit.
v For a list of supported options for your BladeCenter unit, go to
http://www.ibm.com/pc/us/compat/ on the World Wide Web.
System reliability considerations
Attention: To help ensure proper cooling and system reliability, make sure that:
v Each of the module bays on the rear of the BladeCenter unit has either a module
or filler module installed.
v A removed hot-swap module is replaced with an identical module or filler module
within 1 minute of removal.
v Cables for the optional modules are routed according to the illustrations and
instructions in this document.
