network, to link to its complement should the
primary path become non-functional.
The Remote Node Configuration (RNC) software
enables execution of all FCS commands both
locally and remotely. Remote communication is as
simple as connecting a PC to any FOCUS node
and selecting the desired remote node from a
“pull-down” menu.

SNMP trapping enables event notification to user-
defined recipients.
SNMP trapping is available along with Alternate
Path Mode (APM).
[4]: MAIN POWER SUPPLY
Four different power supply voltages ranges are
available for the FOCUS system. These are:
[5]: STANDBY POWER SUPPLY
The FOCUS system can be supplied with a main
and standby power supply. The same choices are
available for the standby power supply as the main
power supply. It is not necessary to have two
power supplies of the same voltage when the
chassis contains a main and standby power supply.
The power supplies can be provided in any combi-
nation. The power supplies are non-load-sharing
and, therefore, fully redundant.
[6]: TRANSCEIVER X1-1
Position 6 details the following options for the I/O
interface for a single transceiver module or for the
first transceiver of a dual transceiver module in
transceiver slot one.
[7]: TRANSCEIVER X1-2
Position 7 details the following options for the I/O
interface for the second transceiver of a dual trans-
ceiver in transceiver slot one.
The standard FOCUS optical modules are
supplied with SC connectors. If your applica-
tion requires ST or FC connectors — which
are also available — please remember to
specify them when ordering (see Pos. 11).
