7 Installing Boards in the Chassis
Before You Install or Remove a Board
Boards may be damaged if improperly installed or handled. Please read and follow the
guidelines in this section to protect your equipment.
Observe ESD Precautions
Use ESD
Wrist Strap
ESD
Emerson strongly recommends that you use an antistatic wrist strap and a conductive
foam pad when installing or upgrading a system. Electronic components, such as disk
drives, computer boards, and memory modules, can be extremely sensitive to
electrostatic discharge (ESD). After removing the component from its protective
wrapper or from the system, place the component flat on a grounded, static-free
surface (and, in the case of a board, component side up). Do not slide the component
over any surface.
If an ESD station is not available, you can avoid damage resulting from ESD by wearing
an antistatic wrist strap (available at electronics stores) that is attached to an active
electrical ground. Note that a system chassis may not be grounded if it is unplugged.
Watch for Bent Pins or Other Damage
!
Caution
Caution
Bent pins or loose components can cause damage to the board, the backplane, or
other system components. Carefully inspect your board and the backplane for both pin
and component integrity before installation.
ECC and our suppliers take significant steps to ensure there are no bent pins on the backplane
or connector damage to the boards prior to leaving our factory. Bent pins caused by improper
installation or by boards with damaged connectors could void the Emerson warranty for the
backplane or boards.
If a system contains one or more crushed pins, power off the system and contact your local
sales representative to schedule delivery of a replacement chassis assembly.
Use Caution When Installing or Removing Boards
When first installing boards in an empty chassis, we recommend that you start at the left of the
card cage and work to the right when cards are vertically aligned; in horizontally aligned cages,
work from bottom to top.
