connections for the chassis, the common
equipment, and the individual channel modules.
The connectors for the chassis and the common
equipment are on the left-hand side of the mother-
board.
3.2 Installation Summary
This section provides a summary of the FOCUS
installation process. This basically involves
installing the system and channel modules,
attaching the interfaces for the channel modules,
connecting the wiring and cables, and configuring
the overall system and the individual channel
modules using the FOCUS Configuration
Software (FCS).
This summary is intended for information only. To
perform a complete installation, please follow the
instructions in the “Hardware Installation and
Connections” section later in this chapter. To
configure your system and the individual channel
modules, please refer to the online help within
FCS.
3.2.1 System and Channel Module
Installation
If necessary, you install the system modules by
inserting them into their assigned slots on the
right-hand side of the chassis, when viewed from
the front. The slots for the Maintenance Module
are on the extreme right of the chassis. The Framer
Module (E1, T1 or TE1) goes in the next slot to
the left. Next are the two slots reserved for trans-
ceivers. You may use one or two transceiver
modules, depending on the desired system config-
uration. To the left of the second transceiver are
two slots reserved for the main and standby power
supplies. You may use one or two power supplies,
again depending on the desired system configura-
tion.
Installing the channel modules is the same as for
the system modules. The only difference is that
you insert them on the left-hand side of the
chassis, in the slots labeled “1” through “12.” The
placement of the channel modules is entirely up to
you. Note, however, that the channel modules and
their rear-panel interfaces must be in the same
position (i.e., they must be connected to each
other through the connectors on the motherboard).
3.2.2 Rear Panel Connectors
The rear panel connectors for the common
equipment are the same for all chassis. On the left-
hand side are two blue male connectors. The
uppermost of these, labeled “P1 EXPANSION,” is
used to connect an expansion chassis. The DB9
PC connection (labeled “P4”) is primarily used for
the FCA Module or a specially made RS-232
cable.
The remaining jack, labeled “TEST,” is for factory
use only in testing the system.
During installation, you connect the power supply
and external alarm contacts to the J13 terminal
block near the middle of the motherboard. If the
FOCUS chassis input/output is fiber optic, you
pass the fiber optic cables through the two holes at
the rear of the chassis labeled “FIBER OPTIC
XCVR-1” and “FIBER OPTIC XCVR-2” and
connect them directly to the fiber optic trans-
ceivers. If the FOCUS chassis has an electrical
DS1 Transceiver Module, you connect the cable
THE REAR DB9 CONNECTOR (P4) ON THE
FOCUS CHASSIS IS PRIMARILY USED FOR
THE FCA MODULE. IT MAY ONLY BE USED
WITH A SPECIAL INTERFACE CABLE. (I.E.
THE CABLE THAT ACCOMPANIES THE FCA
MODULE) –MV4, MV5 ONLY–
CAUTION !
MAINTENANCE, FRAMER & FCA MODULES
SHOULD ONYL BE INSERTED/REMOVED
FROM A DE-ENERGIZED CHASSIS. ALL
OTHER MODULES, INCLUDING CHANNEL,
TRANSCEIVER AND POWER SUPPLIES MAY
BE INSERTED/REMOVED FROM AN
ENERGIZED CHASSIS. HOWEVER IT IS
IMPORTANT TO WAIT A MINIMUM OF 15
SECONDS AFTER REMOVAL OF A PARTIC-
ULAR MODULE BEFORE RE-INSERTING.
CAUTION !
