6. A readily accessible disconnect device that is suitably approved and rated must be incorporated in the
field wiring.
7. The chassis should be connected to an earth ground using the ground stud located between the AC and
DC power sources on the rear panel.
8. The unit must be installed in accordance with the requirements of NEC NFPA 70.
9. The unit must be installed in accordance with Articles 400 and 364.8 of the National Electrical Code
NFPA 70 when installed outside of a restricted access location (that is, in a Central Office, behind a

RACKMOUNT INSTALLATION
The MX2800 STS-1 can be mounted into a standard 19-inch or 23-inch equipment rack. Follow these steps
to mount the unit into a rack:
1. Install the mounting flanges on each side of the MX2800 STS-1 at one of the three available positions.
Install the flanges only with the screws provided.
2. After the flanges have been installed, position the MX2800 STS-1 at the correct location within the
rack and secure the mounting flanges to the mounting rails of the rack.
3. Make all network, DTE, and power connections to the rear of the unit. Refer to
for more information on making the DC power connection.
4. Using the 8-position modular to DB-9 female connector and the 8-position modular to 8-position
modular cable, connect a VT 100 terminal device to the
Two MX2800 STS-1s may be stacked with no spacing between units.
ADTRAN recommends 1U (1.75") of separation above and below the
two stacked units. This spacing allows the unit to dissipate heat. The
design of the MX2800 STS-1 uses the chassis to distribute heat generated
by the internal cards. This arrangement allows the unit to operate without
a cooling fan.
