NSTALLING
THE
RAS 1500 H
ARDWARE
RAS 1500 modules can be mounted in any order, but for ease of
management, we recommend you install RAS 1500 unit on the bottom
of the stack or rack.
Rack Installation
Guidelines
Follow these guidelines when you install RAS 1500 in a rack.
■
Operating Ambient Temperature. If the RAS 1500 is installed in a
closed or multi-module rack assembly, the operating ambient
temperature of the rack environment may be greater than room
ambient temperature. We therefore recommend that you install the
equipment in an environment compatible with the RAS 1500’s
maximum rated ambient temperature. Refer to Appendix A for
detailed technical specifications.
■
Air Flow. Install the RAS 1500 so that the rack has enough air flow for
safe operation.
If the RAS 1500 fails while in a rack, you might have to allow more
spacing between the other equipment in the rack to provide more air
flow.
■
Mechanical Loading. To avoid a hazardous condition, mount the
equipment in the rack evenly and place the rack on a stable surface.
■
Circuit Overloading. Make sure the RAS 1500 is properly connected to
the power supply circuit. This circuit should include overcurrent
protection and proper power supply wiring.
■
Grounding. Maintain reliable grounding of the rack-mounted
RAS 1500. Do not connect the RAS 1500 to a power supply
connection other than the branch circuit.
Grounding the RM
and the PEM
Stack installation of an RM and at least one PEM require proper
grounding. Grounding straps are enclosed in the accessories kit. Install
them as follows:
1
Remove one cover screw on RM and PEM.
2
Install a ground strap between the RM cover and the PEM cover and
reinstall the screws as shown.
