NovaScale Blade BL265 - Installation and User's Guide
3.1.1 System reliability guidelines
To help ensure proper cooling and system reliability, make sure that the following
requirements are met:
•
To ensure proper cooling, do not operate the Blade Chassis without a blade server,
expansion unit, or filler blade installed in each blade bay. See the documentation for
your Blade Chassis for additional information.
• Each microprocessor socket always contains either a microprocessor dust cover and
heat sink filler or a microprocessor and heat sink. If the blade server has only one
microprocessor, it must be installed in microprocessor socket 1.
• Each DIMM socket always contains a memory module or filler.
• Each hot-swap SAS bay contains a SAS storage drive or filler.
• Make sure that the ventilation holes on the blade server are not blocked.
• The blade server battery must be operational. If the battery becomes defective, replace
it immediately. For instructions, see the Problem Determination and Service Guide .
3.1.2 Handling static-sensitive devices
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:
• When you work on a Blade Chassis that has an electrostatic discharge (ESD)
connector, use a wrist strap when you handle modules, optional 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 Blade Chassis).
• Limit your movement. Movement can cause static electricity to build up around you.
• Handle the device carefully, holding it by its edges or its frame.
• Do not touch solder joints, pins, or exposed circuitry.
• Do not leave the device where others can handle and damage it.
• While the device is still in its static-protective package, touch it to an unpainted metal
part of the Blade Chassis or any unpainted metal surface on any other grounded rack
component in the rack in which you are installing the device for at least 2 seconds.
This drains static electricity from the package and from your body.
•
Remove the device from its package and install it directly into the blade server 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 blade server cover or on a metal
surface.
•
Take additional care when you handle devices during cold weather. Heating reduces
indoor humidity and increases static electricity.
