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.

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.

♦

Operates from A or B –42 VDC to –56 VDC input voltage power feeds.

♦

Operates over extended temperature range of –40ºC to +50ºC without fans 

 

or –40ºC to +65ºC with fans.

♦

Storage –40ºC to +85ºC. Relative humidity to 95 percent, noncondensing.

♦

The MX2820 M13 MUX complies with UL 60950, NEBS Level 3, and 

 

GR-1089-CORE.

♦

The MX2820 M13 MUX is intended for installation in restricted access areas only.

♦

The MX2820 M13 MUX is intended for installation in a Type “B” or “E” enclosure.

This device complies with Part 15 of the FCC rules. Operation is subject to the following two 
conditions: (1) This device may not cause harmful interference, and (2) this device must accept 
any interference received, including interference that may cause undesired operation.
Changes or modifications not expressly approved by ADTRAN could void the user’s authority 
to operate this equipment.

All provisioning of the MX2820 M13 MUX will be handled through the SCU. The menu tree 
on the reverse of this Job Aid provides the options and default settings for the MX2820 M13 
MUX.  NOTE: When provisioning the L5 MUX, use the menu tree on this Job Aid, rather than 
the manual, as there are some code differences in the MX2820 Manual.
