Prevent ESD Damage
ESD occurs when electronic components are improperly handled, and it can damage
equipment and impair electrical circuitry, which can result in intermittent or complete
failure of your equipment.
Always follow ESD-prevention procedures when removing and replacing components.
Ensure that the chassis is electrically connected to an earth ground. Wear an ESD-
preventive wrist strap, ensuring that it makes good skin contact. Connect the grounding
clip to an unpainted surface of the chassis frame to safely ground ESD voltages. To
properly guard against ESD damage and shocks, the wrist strap and cord must operate
effectively. If no wrist strap is available, ground yourself by touching the metal part of
the chassis.
For safety, periodically check the resistance value of the antistatic strap, which should
be between one and 10 megohms.
Site Environment
To avoid equipment failures and reduce the possibility of environmentally caused
shutdowns, plan the site layout and equipment locations carefully. If you are currently
experiencing shutdowns or unusually high error rates with your existing equipment,
these considerations may help you isolate the cause of failures and prevent future
problems.
Power Supply Considerations
When installing the chassis, consider the following:
l
Check the power at the site before installing the chassis to ensure that it is free of
spikes and noise. Install a power conditioner, if necessary, to ensure proper
voltages and power levels in the appliance-input voltage.
l
Install proper grounding for the site to avoid damage from lightning and power
surges.
l
The chassis does not have a user-selectable operating range. Refer to the label on
the chassis for the correct appliance input-power requirement.
l
Several styles of AC-input power supply cords are available for the appliance;
make sure that you have the correct style for your site.
l
If you are using dual redundant (1+1) power supplies, we recommend that you use
independent electrical circuits for each power supply.
l
Install an uninterruptible power source for your site, if possible.
