TOTAL ACCESS ® MX2800 CHASSIS
MX2800 M13
CLEI: M3M1AK0B_ _
DESCRIPTION
The MX2800 is an M13 multiplexer that consolidates T1 and E1 signals into a T3 circuit.
The MX2800 houses two hot-swappable controller cards that provide 1:1 redundancy for
the T1 and T3 signals. The unit also houses redundant power supply cards. Features of
the MX2800 include:
■ Built in 1:1 redundancy
■ Hot-swappable controller cards
■ Independent, redundant, hot-swappable power supplies
■ Embedded SNMP and Telnet management
■ Simplified configuration through the VT100 terminal menu structure
■ Capable of backhauling multiple service types (T1/E1)
■ M13 and C-bit signaling support
■ Meets the requirements for NEBS Level 3

bracket. For 19-inch rack applications, attach the brackets with the long flange to the
side of the shelf. For 23-inch rack applications, attach the brackets with the short

rack.
Warning – Care should be taken not to upset the stability of the equipment rack after
installation is complete.
Note: The unit shall be installed in accordance with the requirements of NEC NFPA 70.
Note: When mounting in a rack, two chassis may be mounted together. A space, one unit
high, should be left above and below the two chassis for proper heat dissipation.
4 Make
frame ground connection from the frame ground terminal on the backplane of
the MX2800 to the equipment rack grounding screw using appropriately sized wire
(12-20 AWG preferred.) Use a wire gauge that is at least the same gauge as the power
wiring.

HANDLING PRECAUTIONS REQUIRED.
5 Test
frame ground connection to ensure proper ground. Using a multimeter set to its
lowest resistance range, if applicable, place one lead on the rack’s ground strap and the
other lead on the MX2800 frame ground terminal. The reading should be 1 or 2 ohms.
Greater readings should be investigated.

power connections to the MX2800. The AC version of the MX2800 is
6 Make
provided with a 6-foot power cord, terminated by a three-prong plug which
connects to a grounded 120 VAC, 60 Hz power receptacle. The DC version of the
MX2800 is provided with two four-position modular terminal lug connectors.
The steps below describe the connections for the DC version.
Note: A readily accessible disconnect device, such as a rackmount fuse and alarm
panel that is suitably approved and rated should be incorporated in the fixed
wiring.
Note: Connect to a reliably grounded -48 VDC source, which is electrically isolated
from the AC source.
Note: The branch circuit overcurrent protection should be a fuse or circuit breaker
rated -48 VDC, 3A.
6a. Determine which fuse pairs are to supply power to the shelf.
6b. Remove the fuses from the A and B slots for the pair.
6c. Cut four lengths of appropriately sized wire (12-20 AWG preferred) to reach
from the terminals on the fuse and alarm panel to the power terminals on the
MX2800. Cut two lengths of appropriately sized wire to reach from the equipment rack grounding screw to the ground terminals on the MX2800. If battery
backup is to be used, cut two lengths of wire to reach from the back panel of
the battery backup source to the power terminals of the MX2800.
6d. Using a crimping tool, connect lugs to one end of each wire.
6e. Using a small slotted screwdriver, connect the ends of the wires without the
lugs to the modular connectors. When looking at the holes in the connector
as it will be inserted into the chassis, the wires from left to right are the
battery backup wire, the negative terminal wire, the positive (RET) wire, and
the ground wire. Do this for both modular connectors and plug them into the
chassis.
6f. Using a screwdriver, connect the A and B “PWR FAIL” wires to the A and B
battery backup systems. Connect the A and B negative and return wires to the
A and B fuse and alarm panel connections. Connect the two ground wires to
the equipment rack grounding screw.
7 Apply power and check voltage.
Warning – Installing fuses in the fuse and alarm panel at this stage will provide
power to the shelf. There will be power to pins on the backplane and
inside the shelf. Exercise caution to avoid electric shock.
7a. Install appropriate fuses (3A) in the slots in the fuse and alarm panel that
services the MX2800 shelf.
7b. Using a voltmeter, place the common (normally black) lead on the “RET”
terminal of the DC power terminal block and the DC volts (normally red) lead
on the terminal of the DC power terminal block. The reading should be in the
operating range of -42 VDC to -56 VDC, with a nominal value of -48 VDC.
Note the “-” polarity. Repeat for the other terminal connector.
7c. Remove the fuses from the fuse and alarm panel slots serving the MX2800
until put in service.

The alarm connectors connect to the three contacts of the Form C-type relays on the main board
of the MX2800. These relays are activated any time the MX2800 detects an alarm condition on
the T3 network interface. Both NC (normally closed) and NO (normally open) contacts are
provided. Connect alarms to one of the 3-position modular terminal lug connectors provided
with the shelf and plug into the NONCRITICAL or CRITICAL connector.
