System Reliability Considerations; Handling Static-Sensitive Devices - IBM Brocade 4 Gb SAN Switch Module Installation Manual

System reliability considerations

Attention: To help ensure proper cooling, performance, and system reliability,
make sure that the following requirements are met:
v Each of the module bays on the rear of the BladeCenter unit must be
occupied with either a module or a filler module.
v A removed hot-swap module is replaced with an identical module or filler
module within 1 minute of removal.
v A removed hot-swap blade server is replaced with another blade server or
filler blade within 1 minute of removal.
v The ventilation areas on the sides of the switch module are not blocked.
v You have followed the reliability guidelines in the documentation that comes
with the BladeCenter unit.
Cable requirements for the switch module are described in the IBM
Configuration and Options Guide at http://www.ibm.com/bladecenter/. See the
documentation that comes with the blade server for cable routing information.

Handling static-sensitive devices

Attention: Static electricity can damage the BladeCenter unit and other
electronic devices. To avoid damage, keep static-sensitive devices in their
static-protective packages until you are ready to install them.
To reduce the possibility of electrostatic discharge, observe the following
precautions:
v Limit your movement. Movement can cause static electricity to build up
around you.
v Handle the device carefully, holding it by its edges or its frame.
v Do not touch solder joints, pins, or exposed printed circuitry.
v Do not leave the device where others can handle and possibly damage the
device.
v While the device is still in its static-protective package, touch it to any
unpainted metal surface of the BladeCenter unit chassis or any unpainted
metal surface on any other grounded rack component in the rack you are
installing the device in for at least 2 seconds. (This drains static electricity
from the package and from your body.)
v Remove the device from its package and install it directly into the
BladeCenter unit without setting it down. If it is necessary to set down the
device, put it back into its static-protective package. Do not place the device
on the BladeCenter unit or on a metal surface.
v Take additional care when handling devices during cold weather. Heating
reduces indoor humidity and increases static electricity.
