APPENDIX E – LOW-PROFILE RACK-MOUNT MODEM
DESCRIPTION
Low-profile rack-mount versions are available for all Alliance Series models.
This appendix
applies only to the low-profile rack-mount versions. (Operating information for full-size rack-
mount Alliance Series modems is the same as for their stand-alone counterparts; i.e., as detailed
in the main body of this manual.)
The modified front panel of the low-profile rack-mount modem (Figure E-1) allows 16 low-
profile modems to be housed in a single high-density rack enclosure. (Stand-alone versions of
the Alliance Series modems can be used in a rack enclosure, with the outer shell removed, but
the low-profile design allows more modems to be used in a single rack.)
The software and virtually all of the circuitry in the low-profile units are identical to the software
and circuitry in their stand-alone counterparts, which are described in the main body of this
instruction manual. Except for the absence of the plastic outer shell and interface connectors, the
only difference between the low-profile units and the stand-alone units are in the front panel
design:
•
The low-profile front panel does not have a liquid crystal display (LCD) or control
pushbuttons.
•
The low-profile front panel includes three status indicators (light-emitting diodes, or
LEDs).
•
The low-profile front panel is half as high (1 inch) as the front panel of its stand-alone
counterpart. (When the modem is in the vertical rack-mount position, the front panel
width is 1 inch, as shown in Figure E-1).
The low-profile modem functions exactly the same as its stand-alone counterpart, except
that different methods of control have to be used for configuration and testing, since there
is no LCD or pushbuttons. Therefore, this instruction manual applies to the low-profile
modem except for information pertaining to the LCD and control pushbuttons.
