1.1 Introduction
This manual is intended to provide the information needed for field installation of a Multi-Tech
MR4800E Rack Controller Module (henceforth, MR4800E) into a previously-installed and operational
CC4800 MultiModemManager rack. The CC4800 is shipped standard without an MR4800E; this
manual documents the installation of an optional MR4800E.
1.2 Product Description
The MR4800E contains the processor and memory for intelligent SNMP management of the modems
in the rack. The front panel contains an RJ45 connection for Ethernet UTP attachment to a TCP/IP
Ethernet network and a 9-pin serial connection for PPP attachment to a remote TCP/IP network. The
front panel provides 16 two-color LEDs for MR4800E card status and 4 Ethernet status LEDs.
The MR4800E Rack Controller Module front panel is shown below.

1.3 Features
The MR4800E is an optional part of the MultiModemManager system, Multi-Tech System’s high-
density intelligent modem/rack facility with network management capability. When you have installed
the MultiModemManager hardware and software, you will gain centralized modem rack
management to control modems, continuously monitor connections, log the data, and report fault
events.

2.2 Battery Warning CAUTION
Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type
recommended by the manufacturer. Dispose of used batteries according to the manufacturer’s
instructions.
The MR4800E Controller circuit board includes a battery that maintains the MR4800E’s setup
information when the MultiModemManager is turned off or disconnected from power. The battery can
maintain the setup information for approximately 10 years with no external power, and longer when
the MR4800E is turned on and operating normally. This battery is soldered onto the circuit board and
cannot be replaced by the user.
If, for some reason, the MR4800E’s battery should fail, please contact Multi-Tech Technical Support
at (800) 972-2439 for replacement instructions.
