32 Broadcast Time Delay
Removing the Top Cover
Using a No. 2 Philips head screwdriver, unscrew the three 6-32 Philips head screws attaching the top
cover to the rear panel. Slide the cover back until it is clear of the front panel, and then lift it off.
To re-install the top cover, set the cover on top of the chassis and slide the cover forward until its front
pins engage the front panel. Secure the cover to the rear of the chassis with the three 6-32 screws.
General Handling Precautions
ESD Precautions
Observe electrostatic discharge (ESD) precautions to avoid damaging
static-sensitive components when handling any PC card or disk drive.
• When the case of your server is open and its internal parts are exposed, do not touch
any internal part without first grounding yourself to the chassis.
• Always wear a ground strap or work on an ESD-protective mat.
• DO NOT remove components from protective packaging until you are properly
grounded.
• Handle printed circuit boards by their edges or by the metal bracket.
• Don’t touch any pin, contact, lead or component on the printed circuit boards.
• Keep disk drives in their anti-static package until installed in the server.
Mechanical Concerns
• Be careful when installing I/O cards into your system. Excessive force can damage the
PC boards, cables, hard drives or the motherboard.
• Be sure each board is aligned with its slot in the mating connector before installing.
Use care to not flex any PC boards.
• Interface cable connectors must be mated carefully. Use care to not bend any of the
pins. The connectors provided are keyed to prevent upside-down insertion.
• Interface cables are fragile and must not be pinched. Ensure that their dress does not
restrict airflow from fans or heat sinks within the enclosure.
• Prior to installation, keep disk drives stored in a foam-lined protective carton to protect
them from physical damage.
