Mounting the DC Power Supply
NoteThis equipment is suitable for installation in Network Telecommunications Facilities and locations 
where the NEC applies. This equipment is suitable for installations as part of the Common Bonding 
Network (CBN).
NoteThe Battery Return (BR) input terminal shall be an isolated DC return (DC-I). The DC return terminal 
or conductor shall not be connected to the equipment frame or the grounding means of the equipment. 
DC-powered products have a nominal operating DC voltage of 24 and 48 VDC. Reference American 
National Standard for Telecommunications (ATIS) 0600315.
WarningRead 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 378
The Cisco 800 ISR DC power supply may be mounted to a wall using four #6 pan- or round-head wood 
screws for the mounting holes on the supply.
CautionEach mounting screw must go into a wall stud (wood) or a wall anchor of the appropriate type for the 
wall. Screws into drywall is not sufficient to support the DC power supply.
For attaching to a wall stud, the power supply requires #6 wood screws (round- or pan-head). The 
screws must be long enough to penetrate and tap at least 0.75 inches (19.1 mm) into the supporting 
wood or metal wall stud.
For hollow-wall mounting, the power supply requires the use of appropriate-sized wall anchors that 
work with the drywall thickness the unit is to be installed in. Use hollow-wall anchors that support 
using #6 screws and use #6 pan- or round-head screws to secure the power supply to the wall. Each 
wall anchor should be rated for at least 30 lbs.
CautionIf the screws are not properly anchored, the strain of the DC supply cables could pull the router from the 
wall.

Installing the Cisco 860, 880, and 890 Series Routers
This section describes how to install the Cisco 860 series, 880 series, and 890 series ISRs. These routers 
can either be installed on a table top, or other flat horizontal surface or be mounted on a wall. The 
Cisco 890 series ISRs may be mounted in a rack. Certain Cisco 880 series ISRs can use the same 
ACS-890-RM-19 rack mount kit. For compatibility, see the Cisco 800 Series Comparison Chart. 
This section also describes how to attach WLAN antennas to the Cisco 890 series routers. This section

Warnings
WarningThis equipment needs to be grounded. Use a green and yellow 14 to 18 AWG ground wire to connect 
the host to earth ground during normal use. Statement 242
WarningThis equipment must be grounded. Never defeat the ground conductor or operate the equipment in the 
absence of a suitably installed ground conductor. Contact the appropriate electrical inspection 
authority or an electrician if you are uncertain that suitable grounding is available. Statement 1024
WarningRead 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 378
Note Do not stack anything on top of the router.
Do not cover or obstruct the router vents located on both sides and top of the routers; otherwise, 
overheating could occur and cause damage to the router.
Place router in ventilated area to avoid local air heating.
CautionDo not cover or obstruct the router vents located on both sides of the router; otherwise, overheating could 
occur and cause damage to the router.
CautionDo not place anything on top of the router that weighs more than 10 pounds (4.5 kilograms), and do not 
stack routers on a desktop. Excessive weight on top of the router could damage the chassis.
CautionDo not install the router or power supplies next to a heat source of any kind, including heating vents.
CautionThe top surface of the router is hot since heat is dissipated through the top. Do not keep any object in 
direct contact with the surface for a prolonged period.
Installing on a Table
To install the router on a table or other flat horizontal surface, firmly place the router on a table or other 
horizontal surface. Keep at least 1 inch (2.5 cm) of clear space beside the cooling inlet and exhaust vents.
Connect the chassis to a reliable earth ground. For the chassis ground connection procedures, see the 
“Installing Cisco 890 Series in a Rack” section on page 2-58.

NoteDo not place anything on top of the router.
Mounting on a Wall
The Cisco 860 series, 880 series, and 890 series ISRs have mounting holes on the bottom of the chassis 
for mounting the unit on a wall or other vertical surface.
The mounting holes are bidirectional. You can hang the router with the front bezel facing upward or 
downward.
Keep at least 1 inch (2.5 cm) of clear space beside the cooling inlet and exhaust vents.
TipWhen choosing a location for wall-mounting the router, consider cable limitations and wall structure.
To mount the router on a wall, follow these steps:
Step 1Determine the required distance between mounting holes on the router. Figure 2-42 shows the 
wall-mount holes located on the underside of the router.
NoteFor most router models, the distance between mounting holes is 8.2 inches (208 mm), as shown 
in Figure 2-42. For the Cisco 866 and Cisco 867 models, the distance is 7.85 inches (199 mm). 
Verify the required distance before drilling the holes.

Step 2
Insert the screws, with anchors, into the wall. Leave 1/8 inch (0.32 cm) between the screw head and the 
wall. See Figure 2-43.
Step 3Hang the router on the screw without forcibly pushing towards the wall side. The screw head may 
damage the protection wall inside. Place the power adapter on a nearby horizontal surface. See

Connect the chassis to a reliable earth ground. For the chassis ground connection procedures, see the 
“Installing Cisco 890 Series in a Rack” section on page 2-58.
Installing the Router Ground Connection
The router must be connected to a reliable earth ground. Install the ground wire in accordance with local 
electrical safety standards.
For NEC-compliant grounding, use size 14 AWG (2 mm2) or larger copper wire and a ring terminal 
with an inner diameter of 1/4 in. (5 to 7 mm).
For EN/IEC 60950–compliant grounding, use size 18 AWG (1 mm2) or larger copper wire. 1Two number-10 wood screws mounted on the

To install the ground connection, follow these steps:
Step 1Strip one end of the ground wire to the length required for the ground lug or terminal.
Step 2Crimp the ground wire to the ground lug or ring terminal, using the wire crimper.
Step 3Attach the ground lug or ring terminal to the chassis, as shown in Figure 2-44. For a ground lug, use the 
two provided screws with captive locking washers. For a ring terminal, use one of the screws provided. 
Tighten the screws to a torque of 8 to 10 in-lb (0.9 to 1.1 N-m).
