Installation Options with Racks and Cabinets
You can install the switch in the following types of racks using the rack-mount kit shipped with the switch:
•
Open EIA rack
•
Perforated EIA cabinet
The rack or cabinet that you use must meet the requirements listed in
General Requirements for Cabinets and
Racks, on page 41
The rack-mount kit enables you to install the switch into racks of varying depths. You can use the rack-mount
kit parts to position the switch with easy access to either the port connections end of the chassis or the end of
the chassis with the fan and power supply modules. For instructions on how to install the rack-mount kit, see
the
Installing the Switch, on page 14
.
Airflow Considerations
The switch comes with fan and power supply modules that have either port-side intake or port-side exhaust
airflow for cooling the switch. If you are positioning the port end of the switch in a cold aisle, make sure that
the switch has port-side intake fan modules with burgundy coloring. If you are positioning the fan and power
supply modules in a cold aisle, make sure that the switch has port-side exhaust fan modules with blue colorings.
Installation Guidelines
When installing the switch, follow these guidelines:
•
Record equipment and installation information in the forms presented in
Chassis and Module Information
as you install and configure the switch.
•
Ensure that there is adequate space around the switch to allow for servicing the switch and for adequate
airflow (see
Clearance Requirements, on page 10
).
•
Ensure that you are positioning the switch in a rack so that it takes in cold air from the cold aisle and
exhausts air to the hot aisle. If there is blue coloring on the fan modules, the switch is configured for
port-side exhaust airflow and you must position the module side of the switch in a cold aisle. If there is
burgundy coloring on the fan modules, the switch is configured for port-side intake airflow and you
must position the port of the switch in a cold aisle.
•
Ensure that the chassis can be adequately grounded. If the switch is not mounted in a grounded rack,
we recommend connecting both the system ground on the chassis directly to an earth ground.
•
Ensure that the site power meets the power requirements listed in
. 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 the switch, which can have substantial current draw fluctuations because
of fluctuating data traffic patterns.
