Power Supply Considerations

• Ensure that the chassis cover is secure. The chassis is designed to allow cooling air to flow effectively
• Always follow the ESD-prevention procedures described previously to avoid damage to equipment.

your model.
When installing the chassis, consider the following:
• Check the power at the site before installing the chassis to ensure that it is "clean" (free of spikes and
• Install proper grounding for the site to avoid damage from lightning and power surges.
• The chassis does not have a user-selectable operating range. Refer to the label on the chassis for the
• Several styles of AC-input power supply cords are available; make sure that you have the correct style
• Install an uninterruptible power source for your site, if possible.
• If you are using dual redundant (1+1) power supplies, we recommend that you use independent electrical

Rack Configuration Considerations

Consider the following when planning a rack configuration:
• Standard 19-in. (48.3 cm) 4-post EIA rack with mounting rails that conform to English universal hole
• The rack-mounting posts need to be 2 to 3.5 mm thick to work with the slide rail rack mounting.
• If you are mounting a chassis in an open rack, make sure that the rack frame does not block the intake
• If your rack includes closing front and rear doors, the doors must have 65 percent open perforated area
• Be sure enclosed racks have adequate ventilation. Make sure that the rack is not overly congested as each
