The following sections cover the steps required to install components and perform maintenance
on the ISS C1104-GP6 chassis. For component installation, follow the steps in the order given to
eliminate the most common problems encountered. If some steps are unnecessary, skip ahead to
the step that follows.
Important: Always disconnect the AC power cord(s) before adding, changing or installing any
internal hardware components that require removal of the chassis cover.

Electrostatic discharge (ESD) can damage electronic components. To prevent damage to any
printed circuit boards (PCBs), it is important to handle them very carefully. The following
measures are generally sufficient to protect your equipment from ESD damage.
• Use a grounded wrist strap designed to prevent static discharge.
• Touch a grounded metal object before removing any board from its anti-static bag.
• Handle a board by its edges only; do not touch its components, peripheral chips, memory
modules or gold contacts.
