DESCRIPTION
The MX2820 M13 MUX is a plug-in unit for the MX2820 chassis that provides an M13
multiplexer function to the MX2820 system. Two MX2820 M13 MUX cards are used together
to provide a redundant M13 multiplexer circuit. The MX2820 M13 MUX:
♦ Provides 1:1 redundancy
♦ Meets the requirements for NEBS Level 3.
INSTALLATION AND TURNUP
After unpacking the unit, inspect it for damage. If damage is found, file a claim with the carrier
and then contact ADTRAN Customer Service. Refer to the Warranty Statement on this Job Aid.
This module occupies a MUX slot in the MX2820 chassis. To install the M13 MUX in the
chassis, perform the following steps:
1. Pull the ejector tab into the down position and gently but firmly push the MUX into the
selected MUX slot. Simultaneous thumb pressure at the top and at the bottom of the unit
will ensure a good seat of the MUX into the backplane connector.
2. Push the ejector tab up and closed against the front panel.
Upon installation, the MUX will begin a self-test. This is followed with the LEDs reflecting
the true state of the hardware.
