2.1.3 Rack-Mount Modem Installation
The 2201 Rack Chassis is designed for installation in a standard 19-inch wide
equipment rack. Tabs are provided on each side of the unit, and are predrilled for
standard spacing. Refer to the 2201 Rack Chassis User Manual for more information
on installing a 2201.
When installing a modem or panel, the Nylatch retainer should be in an outward, or
released condition. Slide the modem card into the rack until it engages fully with the
PC board edge connector, then push the Nylatch retainers in.
For each modem installed, compatible communications cables and appropriate fiber
optic cables, terminated with the appropriate type connectors, will be required.
2.1.4 Fiber Cable and Connectors
The Transmit (Tx) from the local modem should be connected to the Receive (Rx) at
the remote modem and the Receive (Rx) from the local modem should be connected

The connectors are clearly marked as to their function, either Transmit (Tx) or
Receive (Rx) on the back panel of the 2240 standalone units. Figure 2-1 is shown
