RACKMOUNT INSTALLATION
The MX2800 STS-1 can be mounted into a standard 19-inch or
23-inch equipment rack. Follow these steps to mount your unit into
a rack:
1. Prepare the MX2800 STS-1 mounting ears by scraping the
paint away from the mounting ears’ portion that makes contact
with the rack and the portion where the screw mounts into the
side of the MX2800 STS-1.
2. Install the mounting flanges on each side of the MX2800 STS-1
at one of the three available positions.
3. 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.
4. Make all network, DTE, and power connections to the rear of
the unit. See Power Up on page 2-2 for more information on
making the DC power connection.
5. 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
CRAFT port on the front panel of
the unit.
Be sure to install the flanges with the screws provided.
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 unit's internal cards. This design allows the unit to
operate without a cooling fan, which increases its overall reliability.
