Plan your site configuration and prepare the site before installing the chassis.
Planning and Maintenance Records,"
Record the information listed in
install and configure the switch.
Ensure that there is adequate space around the switch to allow for servicing the switch and for
adequate airflow (Appendix B, "Technical Specifications,"
Ensure that the air-conditioning meets the heat dissipation requirements listed in
"Technical Specifications."
Ensure that the cabinet or rack meets the requirements listed in
Installation."
Jumper power cords are available for use in a cabinet. See the
page C-11.
Ensure that the chassis is adequately grounded. If the switch is not mounted in a grounded rack,
Cisco recommends connecting both the system ground on the chassis and the power supply ground
to an earth ground.
Ensure that the site power meets the power requirements listed in
Specifications." If available, you can use an uninterruptible power supply (UPS) to protect against
power failures.
Avoid UPS types that use ferroresonant technology. These UPS types can become unstable
with systems like the Cisco MDS 9000 Family, which can have substantial current draw
fluctuations because of fluctuating data traffic patterns.
Ensure that circuits are sized according to local and national codes. For North America, the 845-W
power supply requires a 15-A or 20-A circuit.
If you are using a 200- or 240-VAC power source in North America, the circuit must be protected
by a two-pole circuit breaker.
To prevent loss of input power, ensure the total maximum loads on the circuits supplying
power to the switch are within the current ratings for the wiring and breakers.
Use the following screw torques when installing the switch:
– Captive screws: 4 in-lb
– M3 screws: 4 in-lb
M4 screws: 12 in-lb
–
10-32 screws: 20 in-lb
–
12-24 screws: 30 in-lb
