3.1.3 Installation Location
Install the FOCUS in an area which is free from:
•Temperature exceeding environmental
limits
• Corrosive fumes
•Dust
•Vibration
3.1.4 The FOCUS Chassis
The FOCUS chassis comprises three main parts:
the cover, the metal rack, and the motherboard.
Following are descriptions of each, including their
role in the assembly, or installation, process.
3.1.4.1 The Chassis Cover
The cover of the FOCUS chassis has a fixed tab
on the left side and a sliding tab on the right side,
which contains a hole for placing a meter seal, if
desired. It is constructed of metal for rigidity and
electromagnetic interference immunity (EMI).
Holes are punched so that you can easily see the
status LEDs on all installed system and channel
modules without removing the cover.
A plastic appliqué is applied to the face of the
cover to guard against scratches and provide
labeling for the status LEDs, which are visible
through the plastic appliqué. It is not possible to
install the cover with any FOCUS module not
fully installed.
3.1.4.2 The FOCUS Rack
The metal rack includes 24 module slots into
which you insert the FOCUS system and channel
modules. Plastic appliqués are provided above and
below the module slots, with labels for the system
modules and guide marks for the channel
modules. You may write on and erase these labels
with a standard #2 lead pencil. This permits easy
identification of the installed channel modules.
A nameplate is affixed to the inside right side of
the metal rack. The style number on the nameplate
reflects the configuration of the system modules
when the chassis was shipped from the factory.
The sides of the chassis hold adjustable flanges to
permit you to mount the FOCUS unit at varying
depths within a 19” (482.6 mm) rack. Perforated
protection screens are installed on the top of the
chassis to prevent small particles from falling onto
the electronics on any of the circuit boards.
You may use the FOCUS either in one of the
following configurations:
•Mounted in a fixed-rack cabinet.
•Mounted in a swing-rack cabinet.
•Mounted on an open rack.
or in your own, customer-specified configuration.
3.1.4.3 The FOCUS Motherboard
The FOCUS motherboard, or backplane, comes
already installed in the FOCUS chassis. It is
mounted on the rear of the chassis. The chassis
serial number identification is affixed near the
lower left corner of the motherboard, when
viewed from the rear.
The front of the motherboard, which is on the
inside of the chassis, provides the connections for
the system modules, or common equipment, and
the channel modules. When you insert the
modules into the chassis, they connect to the
inside face of the motherboard.
The motherboard’s rear panel, which is on the
outside of the chassis, provides the interface
IF YOU ARE USING THE FOCUS WITH A
SWING-RACK CABINET, MAKE SURE THAT
THE CABINET IS FIRMLY FASTENED BEFORE
OPENING THE RACK (TO PREVENT TIPPING).
