In preparation for bracket and chassis installation, determine:
Whether the equipment will be rack-mounted.
Width of the rack: 19
″
(483 mm) or 23
″ (
584 mm).
Whether the rack has mounting rails with threaded or non-threaded screw
holes.
The number of POTS/ISDN splitter chassis required.
NOTES:
Install chassis in the rack from the bottom up to maintain stability.
If access to the back of the unit will be inconvenient when the chassis is
mounted, connect the grounding wire before installing the chassis in the rack.
Installation into a Rack without Threaded Screw Holes
Procedure
To install a chassis in a rack without threaded screw holes:
1. Install the mounting brackets appropriate for your rack.
2. Determine where the chassis will be placed in the rack. Mark the front rail
where the four holes in the mounting brackets will be.
3. Slide a self-retaining nut onto each marked rail hole and align the hole of the
nut with the hole in the rail.
4. Line up the chassis mounting brackets with the self-retaining nuts.
5. Holding the chassis in place, loosely install the bottom screws first and then
the top screws.
6. Tighten all screws firmly using a Phillips screwdriver.
Repeat the process for each POTS/ISDN splitter chassis. POTS/ISDN splitter
chassis can be mounted directly on top of each other.
