The CHS2U-US chassis can be mounted on the wall, the floor, a stand or in a
rack. The CHS2U GW-US chassis can be mounted on the wall, a stand or in a
rack. Plywood should first be installed on the wall where the chassis will be
positioned, to allow for secure anchoring. It has a bracket, which can be used
to secure each chassis in any installation. Ensure that enough space is
available to allow the installation of the additional chassis above and below
the Controlling Chassis.
The system requires a 3-prong dedicated 110 VAC 60 Hz circuit (NEMA 5-15
receptacle) located within seven feet of the AC receptacle. Telco should install
the RJ21X to the right of the Controlling Chassis. Extension blocks should be
installed to the left of the Controlling Chassis.
Chassis are shipped fully assembled. The following are included with the
chassis:
19" Chassis (CHS2U-US)

Power Failure Transfer

The Power Failure Transfer relays are located on the COIU blades (CN3).
When selecting a Single Line Telephone for power failure transfer, make sure
it matches the CO line dialing type (10 pps, 20 pps, or DTMF) where it is
connected. Each COIU blade supports two power failure transfer
connections. During a power failure condition, CO Ports 1 and 2 on the COIU
Blade are used for Power Failure Transfer relays 1 and 2 consecutively.

Power Failure and FAX Branch Connection do not function simultaneously on the same
port. Use Program 14-02-21 (Fax Branch Connection) to enable this feature per trunk.
