Installing the Switch
Installation Procedures
For redundant AC power, connect the external power supply to the switch
using one of the supplied RPS cables. For redundant or additional PoE/PoE+
power, connect the external power supply to the switch using one of the
supplied EPS cables. The RPS and EPS cables are 2.00 meters (6.56 feet) in
length. These cables are identical. If accidentally cross connected, nothing
will happen. No power will flow until properly connected.
External Power Supply LEDs
The external power supply LEDs are duplicated on the front and back of the
units. The following graphics show examples of the back of the 620 EPS/RPS
and the front and back of the 630 RPS/EPS. There are dual colored (green/
orange) LEDs for each RPS and EPS port:
