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:
Attach the adapter tray to the back of the switch by tightening the two
1
mounting screws.
Insert the power adapter into the tray.
2
Connect the DC cable of the power adapter to the switch by plugging
3
the cable in to the connector located at the back of the switch
labeled "RPS."
Attach the AC power cord to the power adapter and connect the AC
4
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:
Set the switch on the flat surface and check for proper ventilation.
1
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.
Attach rubber feet on each marked location on the bottom of
2
the chassis.
The rubber feet are optional, but recommended to keep the unit from
slipping.
