10.5.4 optiPoint 500 key modules and adapters power supply
Power is generally supplied to optiPoint 500 telephones by the system via the U
P0/E
interfaces.
When certain optiPoint 500 key modules and adapters are used, the power supply from the
system is not adequate.
Table 10-8 indicates which optiPoint 500 key modules require an additional external power sup-
ply. In this case, the local power supply units described in Section 10.8.1.1 are used.

1 It is assumed that only one key module or adapter is implemented on each optiPoint 500 telephone. An additional external
power supply may be required if several key modules and adapters are implemented on an optiPoint 500 telephone or the
maximum U
P0/E
interface range is reached by the optiPoint 500 telephone. The telephone test described in Section 12.4.11
will establish whether or not additional power is required from a local power supply.

2 The local power supply is series-connected to the optiPoint 500 telephone: the “digital” RJ6 jack on the local power supply
must be connected to the optiPoint 500 telephone. The other RJ6 jack must be connected to the U
P0/E
interface on the
system.
optiPoint BLF required connected directly

3 The local power supply is connected directly to the optiPoint BLF: one of the two RJ6 jacks on the local power supply unit
must be connected with the center jack (indicated by the symbol of a power supply unit) on the optiPoint BLF. A local power
supply can supply a maximum of two optiPoint BLFs.
