6. When inserted into an active chassis, the modem's LEDs will display amber while booting. If
a DMM is installed and operating, the DMM will detect the presence of the modem, and
begin reporting modem status on appropriate software screens. For LED activity, see the LED
section of this manual.
7. To avoid configuration errors, attach the appropriate cables to the modem's ELIMs and
OLIMs, carefully labeling all Tx and Rx cables clearly.
8. If no configuration errors are present, data will begin passing.
2.1.1 Inserting an ELIM or OLIM
ELIMs and OLIMs (Electrical or Optical Line Interface Modules) slide in and out of the modem's
main module, much as the modem itself slides into the Chassis. The rack mount cards and the
stand alone units use the same LIMs.
ELIMs are always positioned in the top slot, and OLIMs on the bottom.
2.2 Unpacking and Installing the Stand Alone Modem
Each 2461 modem is factory tested and shipped in protective cartons. After unpacking the unit
and accessories, retain the shipping carton and protective packing for reuse in the event a need
arises for returning it to the factory.
The stand alone modem may be installed on a desktop or rack mounted (see Figure 13). Ensure
that cables are away from foot traffic. The operator must have access to the rear of the modem
(for cable and dry alarm contact attachment), and the front of the modem (for terminal interface
access and viewing the modem's LEDs).
