SINGLE/DUAL RACKMOUNT KITS
Dual-Unit Installation
The components that you’ll use for dual-unit installation are the two short brackets and two side rails. Take these
steps, referring to the illustrations below:
1. Attach a bracket to each of the units’ cases (one bracket to one unit’s left side, one to the other unit’s right
side) using two of the included screws and flatwashers. Insert the screws in the two front holes on the units’
sides. (Nuts are already in place, mounted on the side walls inside the unit.)
2. Attach a rail to each of the unit’s cases (one rail to one unit’s right side, the other rail to the other unit’s left
side) by inserting four of the included screws and flatwashers in the case’s four side holes. These rails must
be attached “opposingly,” so that the narrow flange of one rail faces the wide flange of the other.
Attaching the RM523’s short bracket and side rail.
3. Fasten the two units together by sliding one of the rails into the other.
4. Cover the ends of the joined rails with the included plastic caps in order to protect the rail ends and keep
the rails from sliding.
Fastening the two units together.
After you finish this assembly, the units are ready for mounting. Fasten the brackets to the side rails of
your 19" rack with four screws, cage nuts, etc. (These aren’t included in the Kit.)
