Mounting the Cisco 812 ISR Below a Suspended Ceiling
The recommended power option for the Cisco 812 ISR, when mounted below a suspended ceiling, is the
Cisco C810-POE-SPL (PoE+ splitter) with the use of the supplied 1.3 meter power cable and Cat5 cable
(Plenum rated). The cables can be hidden above the suspended ceiling for a clean installation. See the
“Installing the Cisco PoE+ Splitter” section on page 2-2 for details on installing the PoE+ splitter.
Use a flat screwdriver if there is a need to remove the GE/console cables.
To mount the Cisco 812 ISR below a standard or recessed suspended ceiling, perform these steps.
Step 1 Decide where you want to mount the router on your suspended ceiling.
Step 2 Open the ceiling grid clip completely.
Step 3 Place the ceiling grid clip over the T-rail and close it to the appropriate detent (A, B, or C).
Step 4 Use a screwdriver to tighten the two ceiling grid clip locking screws to prevent the clip from sliding
along the T-rail.
Step 5 Observe the ceiling grid clip width detent letter (A, B, or C) that corresponds to the T-rail width.
Step 6 Align the corresponding holes (A, B, or C) on the mounting bracket over the mounting holes on the
ceiling grid clip.
