Installing the Router
Mounting a Cisco 2901 or 2911 Router on a Wall
This section explains how to mount Cisco 2901 and Cisco 2911 routers on a wall or other vertical
surface. We do not recommend mounting a Cisco 2921, 2951, or Cisco 3900 series router on a wall.
The following warning applies to Cisco 2901 and 2911 routers:
Warning
This unit is intended to be mounted on a wall. Please read the wall mounting instructions carefully
before beginning installation. Failure to use the correct hardware or to follow the correct procedures
could result in a hazardous situation to people and damage to the system.
Statement 248
Tip When choosing a wall-mounting location, consider cable limitations and wall structure.
Note The Cisco 2901 and Cisco 2911 routers use brackets designed for the 19-inch EIA rack-mounting, the
part number 700-16559-01 is stamped on the bracket (shown in Figure 3-15).
Attaching Brackets to the Router for Wall Mounting
Attach the standard brackets to the chassis using the four screws provided for each bracket.
Attaching the Router to a Wall
Attach the router to the wall using the brackets previously attached. Use attachment hardware that you
provide as follows:
• For attaching to a wall stud, each bracket requires two number-10 wood screws (round- or pan-head)
with number-10 washers, or two number-10 washer-head screws. The screws must be long enough
to penetrate at least 1.5 inches (38.1 mm) into the supporting wood or metal wall stud.
• For hollow-wall mounting, each bracket requires two wall anchors with washers. Wall anchors and
washers must be size number 10.
• Route the cables so that they do not put a strain on the connectors or mounting hardware.
• The NEBS air baffle (Cisco 2911) should not be used when wall-mounting the router.
Caution This unit is intended to be mounted on a wall. Please read the wall mounting instructions carefully before
beginning installation. Failure to use the correct hardware or to follow the correct procedures could
result in a hazardous situation to people and damage to the system.
Caution The router must be mounted with the power connections oriented downward. Failure to do so could
present a fire hazard.
