2.8 Redundancy and Alternative Powering Configurations

The PTP 500 Series Bridge can be powered from an external DC source and can be provided

with power supply redundancy as follows:

• External DC supply only (Figure 6): This configuration is fo

r use where there is no mains

supply.

• External DC supply and AC supply (Figure 7): This configuratio

n provides redundancy

through the use of mains and DC supply.

• External DC supply and redundant AC Supply (Figure 8): This configuration guards

again

st mains failure and failure of the DC output of single PIDU Plus.

NOTE

The use of DC supplies of less than 55v will reduce the usable distance between the

PIDU Plus and ODU.

CAUTION

The maximum distance from the ODU to the connected network equipment is

100 m (330 ft) when using 100BaseT.
