Managed Stackable Layer 3 Fast Ethernet Switches Hardware Installation Guide
Connecting a Redundant Power Supply
The FSM7328PS and FSM7352PS switches have a redundant power supply
connector in the back.

The location of the Redundant power supply connector on your switch may differ
from the illustration.
You can connect a DC-to-DC power supply to the switch in case the primary
power supply fails. To connect a redundant power supply to the switch, first turn
off the switch. Then connect the redundant power supply to the switch. Once all
connections are completed, apply power to the switch.
Connecting Equipment to the Switch
You can connect devices, an SPF Gigabit Ethernet module, and a console to the
switch.
RJ-45 Ports
The switch uses Auto Uplink technology, which enables you to attach devices
using either straight-through or crossover cables. Use a Category 5 (Cat5)
unshielded twisted-pair (UTP) cable terminated with an RJ-45 connector.

Note: Ethernet specifications limit the cable length between the switch
and the attached device to 328 feet (100 meters).
