Installing the PSU(s)
To install the PSU(s) in the switch, follow these steps:
1. From the rear of the switch, using a screwdriver, remove the two screws holding the faceplate covering the bay in which the power supply will be installed.
Then, remove the faceplate. If only installing one power supply, keep the faceplate installed on the open bay.
2. Carefully slide the PSU into the open power supply slot until the locking lever clicks into place.
3. If installing a second PSU, repeat steps 1 and 2.
Connecting to AC Power
Once the PSU(s) have been installed correctly into the switch, follow these steps to connect to AC power:
1. Plug the appropriate power cord into a grounded, 3-pin, AC power source.
2. Insert the plug on the other end of the power cord directly into the socket on the PSU.
3. Check the LED indicators on the PSU and switch front panel as the unit is powered on to verify that power is being received. If not, recheck the PSU and
power cord connections at the AC supply source and PSU.
4. If you have installed a second PSU, repeat steps 1 to 3.
