System Reliability Guidelines; Handling Static-Sensitive Devices; Returning A Device Or Component - IBM System x iDataPlex dx360 M2 Problem Determination And Service Manual

System reliability guidelines

To help ensure proper cooling and system reliability, make sure that the following
requirements are met:
v Each of the drive bays has a drive or a filler panel and electromagnetic
v You have followed the cabling instructions that come with optional adapters.
v You have replaced a hot-swap drive within 2 minutes of removal.
v The system-board tray battery is operational. If the battery becomes defective,
v Microprocessor socket 2 always contains either a microprocessor baffle or a
v You have replaced one or both system-board trays within 2 minutes of removal.
v For a 2U compute server, do not operate the upper system-board tray with the

Handling static-sensitive devices

Attention:
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 Limit your movement. Movement can cause static electricity to build up around
v The use of a grounding system is recommended. For example, wear an
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 system-board
v Take additional care when handling devices during cold weather. Heating reduces

Returning a device or component

If you are instructed to return a device or component, follow all packaging
instructions, and use any packaging materials for shipping that are supplied to you.
