Mounting the Cisco MWR 1941-DC-A Router
Rack-Mounting Configuration Guidelines
The following information will help you plan your equipment rack configuration:
•
When mounting the router to an equipment rack, ensure that the rack is bolted to the floor.
•
Since you will probably be installing more than one router into the rack, ensure that the weight of
all the routers installed does not make the rack unstable.
Caution
Some equipment racks are also secured to ceiling brackets, if necessary, due to the weight of the
equipment in the rack. Make sure that the rack you are using to install the routers is secured to the
building structure.
•
As mentioned in the
“Air Flow Guidelines” section on page 2-5
, maintain a 6-inch (15.2-cm)
clearance at the front and rear of the router to ensure adequate air intake and exhaust.
•
Avoid installing the routers in an overly congested rack. Air flowing to or from other routers in the
rack might interfere with the normal flow of cooling air through the routers, increasing the potential
for overtemperature conditions within the routers.
•
Allow at least 19 inches (48.7 cm) of clearance at the front and rear of the rack for router
maintenance.
•
Follow your local practices for cable management. Ensure that cables to and from the routers do not
impede access to perform equipment maintenance or upgrades.
Attaching the Rack-Mounting Brackets
You rack-mount a Cisco MWR 1941-DC-A router with the front of the chassis facing forward. The
rack-mounting brackets and six #8-32 x 0.37-inch screws are provided in a rack-mounting bracket kit
(Cisco part number 69-0791-01). Use a Number 2 Phillips screwdriver to install the rack-mounting
bracket screws.
Perform the following procedure to mount the Cisco MWR 1941-DC-A router to the rack-mounting
brackets for a 19-inch (48.3-cm) equipment rack.
Step 1
Locate the mounting holes of the Cisco MWR 1941-DC-A router for the mounting (see
Figure 3-1
).
Step 2
Align the rack-mounting bracket with the Cisco MWR 1941-DC-A router and position with the three
#8-32 x 0.37-inch screws (provided).
Step 3
Insert the screws (three places) and tighten using a Number 2 Phillips screwdriver.
Step 4
Repeat Steps
2
and
3
for the other rack-mounting bracket.
Step 5
You are now ready to install the Cisco MWR 1941-DC-A router into the equipment rack.
