Redundant Power System 

PowerConnect RPS-60

The optional external redundant power system PowerConnect RPS-60 
provides a second, redundant power supply for your switch, eliminating the 
power supply as a single point of failure. To use the RPS-60:

1

Attach the adapter tray to the back of the switch by tightening the two 

mounting screws.

2

Insert the power adapter into the tray.

3

Connect the DC cable of the power adapter to the switch by plugging 

the cable in to the connector located at the back of the switch 

labeled "RPS."

4

Attach the AC power cord to the power adapter and connect the AC 

power cord into a power outlet.

The switch is now using both power supplies simultaneously. You can 
monitor the status of the two power supplies via the front panel LEDs.

Mounting Kit Instructions

These switches come with mounting brackets and screws for rack mounting 
and rubber feet for stationing on a flat surface.

Installing on a Flat Surface

The switch can be installed on any appropriate level surface that can safely 
support the weight of the switches and their attached cables. There must be 
adequate space around the switch for ventilation and access cable 
connectors.

To install the switch on a flat surface, complete the following steps:

1

Set the switch on the flat surface and check for proper ventilation.
Allow at least 2 inches (5.1 cm) on each side for proper ventilation and 

5 inches (12.7 cm) at the back for power-cord clearance.

2

Attach rubber feet on each marked location on the bottom of 

the chassis.
The rubber feet are optional, but recommended to keep the unit from 

slipping.
