System Reliability Guidelines; Handling Static-Sensitive Devices - IBM HS22 - BladeCenter - 7870 Installation And User Manual

System reliability guidelines

Use this information to make sure that the blade server meets the proper cooling
and reliability guidelines.
To help make sure that proper cooling and system reliability requirements are met,
review the following guidelines:
v To ensure proper cooling, do not operate the BladeCenter unit without a blade
v Each microprocessor socket always contains either a microprocessor dust cover
v Each DIMM socket always contains a memory module or filler.
v Each hot-swap SAS bay contains a SAS storage drive or filler.
v Make sure that the ventilation holes on the blade server are not blocked.
v The blade server battery must be operational. If the battery becomes defective,

Handling static-sensitive devices

Use this information to observe the static-sensitive device requirements.
Attention: Static electricity can damage the blade server 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 damage from electrostatic discharge, observe the
following precautions:
v When you work on a BladeCenter unit that has an electrostatic discharge (ESD)
v Limit your movement. Movement can cause static electricity to build up around
v Handle the device carefully, holding it by its edges or its frame.
v Do not touch solder joints, pins, or exposed circuitry.
v Do not leave the device where others can handle and damage it.
v While the device is still in its static-protective package, touch it to an unpainted
v Remove the device from its package and install it directly into the blade server
v Take additional care when you handle devices during cold weather. Heating

devices, or blade servers. To work correctly, the wrist strap must have a good
contact at both ends (touching your skin at one end and firmly connected to the
ESD connector on the front or back of the BladeCenter unit).
