Selecting a Power Configuration

Selecting a Power Configuration
The power configurations available for the RoamAbout R2 include local power, remote
power, and redundant power.

Local Power Configuration

In the local power configuration, the RoamAbout R2 receives operating power directly
from one local source (such as a power supply connected to a nearby wall outlet). The
output plug of the power supply is connected directly into the RoamAbout R2
chassis-mounted power connector.

Remote Power Configuration

In the remote power configuration, the RoamAbout R2 receives operating power over the
Ethernet cable from one remote source (such as a power supply installed in the wiring
closet or other remote location). This option requires installing the remote power injector
in the same location as the power supply. The output of the power supply is connected to
the remote power injector. The Ethernet interface cable also plugs into the remote power
injector. Another Ethernet cable is connected between the injector and the RoamAbout R2
to provide input/output signals and power.
Enterasys offers an optional rack mount kit that allows installation of up to three remote
power injectors into one standard rack-mount panel. See
page 2-5 for more information.

Redundant Power Configuration

The RoamAbout R2 can be connected to an independent source of local power and to an
independent source of remote power. If one of these power sources goes down, the
RoamAbout R2 continues uninterrupted operation with power received from the other
(redundant) power source.

CAUTION: Label the remote power injector cable at the opposite end
from the power injector (RoamAbout R2 or wall jack) to ensure that
this cable is not connected to another device. The procedures in
Chapter 3 offer sample text.
