Lenovo ThinkServer RD240 - System Reliability Guidelines; Handling Static-Sensitive Devices

v Have a small flat-blade screwdriver available.
v To view the error LEDs on the system board and internal components, leave the
server connected to power.
v You do not have to turn off the server to install or replace hot-swap fans,
redundant hot-swap ac power supplies, or hot-plug USB devices. However, you
must turn off the server before performing any steps that involve installing,
removing, or replacing adapter cables or non-hot-swap optional devices or
components.
v After completing any installation, removal, or replacement procedure, reinstall
all safety shields, guards, labels, and ground wires.
v For a list of supported optional devices for the server, go to

v When working inside the server, you might find some tasks easier if you lay the
server on its side.
System reliability guidelines
To help ensure proper cooling and system reliability, make sure that you follow
these guidelines:
v Every drive bay has an internal drive installed or an Electro Magnetic
Compatibility (EMC) shield installed.
v If the server has redundant power, every power supply bay has a power supply
assembly installed.
v Leave adequate space around the server to make sure that the server cooling
system works well.
v Properly route the cables. For some options, such as PCI cards, follow the
cabling instructions that come with the options.
v Make sure that you replace a failing fan within 48 hours.
v When replacing a hot-swap drive, install the new hot-swap drive within two
minutes of removal.
v Do not remove any air duct or air baffles while the server is running. Operating
the server without the air duct or air baffles might cause the microprocessor to
overheat.
v The second microprocessor socket always contains either a microprocessor socket
cover or a microprocessor.
Handling static-sensitive devices
Attention
Do not open the static-protective package containing the new part until the defective part
has been removed from the server and you are ready to install the new part. Static
electricity, although harmless to you, can seriously damage server components and parts.
When you handle server parts and components, take these precautions to avoid
static-electricity damage:
v Limit your movement. Movement can cause static electricity to build up around
you.
v Wear an electrostatic-discharge wrist strap, if one is available.
v Always carefully handle the parts and other components (such as PCI cards,
memory modules, system boards, and microprocessors) by its edges or its frame.
Do not touch solder joints, pins, or exposed circuitry.
