Part 1: Install a Power Supply in the Switch (If It Is Not
Installed)
1. Ensure that you have the correct power supply:
− Verify that the ejector lever and the arrows on the fan tray handles on the back of
the switch all point in the same direction.
− Verify that power supply and fan tray labels match—all say
CAUTION: Operating the switch with an incorrect power supply might cause
the switch to overheat.
2. Taking care not to touch power supply pins, leads, or solder connections, remove the
power supply from the bag.
3. Using both hands, place the power supply in the power supply slot on the back panel
of the switch and slide it in until it is fully seated.
4. Repeat these steps for a second power supply, if needed.
Part 2: Mount the Switch
NOTE: A switch can weigh up to 40 lb (18 kg) depending on the components that
are installed. Installation requires one person to lift the switch and a second person
to secure it to the rack.
1. Place the rack in its permanent location, allowing adequate clearance for airflow and
maintenance, and secure it to the building structure.
2. If your site has hot and cold aisle requirements, check the labels on the back of the
switch to determine whether to front-mount or back-mount the chassis:
−
EXHAUST
−
INTAKE
NOTE: If you are mounting multiple units in the rack, mount the heaviest unit at the
bottom and mount the others from bottom to top in order of decreasing weight.
3. Determine the location on the rack where you want to mount the switch.
EXHAUST or INTAKE .
4. If your rack requires cage nuts, install a round-hole cage nut (clip nut) or square-hole
cage nut—and a washer—in 4 appropriately spaced holes at the same level on each
rack post.
—Hot air exits the fan tray and power supplies (front-to-back airflow).
—Hot air exits the front of the chassis (back-to-front airflow).
