What to Do after Installing the Router Hardware
CautionIf you plan to place the router on a desk or table, do not place anything on top of the router that weighs in excess of 10 pounds (4.5 kg). Excessive weight on top could damage the chassis.
Required Tools and Parts
Following are the tools and parts required to install the router:

Installing the Rubber Feet
This section explains how to install the rubber feet on the bottom of the chassis. If you want to rack-mount the chassis, skip this section and proceed with the next section, "Rack-Mounting the Chassis." If you want to wall-mount the chassis, skip this section and proceed with the section "Wall-Mounting the Chassis" later in this chapter.
Before placing the router on a desktop, shelf, or other flat, secure surface, perform the following steps to install the rubber feet:
Step 1

Step 3
Figure 1-2 Installing the Rubber Feet
Rack-Mounting the Chassis
This section describes the procedures for rack-mounting the chassis. Your chassis ships with a bracket for use with a 19-inch rack or, if specified in your order, an optional larger bracket for use with a 24-inch rack. The brackets are shown in Figure 1-3.
Figure 1-3 Identifying the Brackets
Attaching the Brackets
To install the chassis in a rack with the front panel forward, attach the brackets as shown in Figure 1-4 or Figure 1-5.
Figure 1-4 19-Inch Rack Installation—Front Panel Forward
Figure 1-5 24-Inch Rack Installation—Front Panel Forward
To install the chassis in a rack with the rear panel forward, attach the brackets as shown in Figure 1-6 or Figure 1-7.

Figure 1-7 24-Inch Rack Installation—Rear Panel Forward
To install the chassis in a center-mount telco rack, attach the brackets as shown in Figure 1-8 or Figure 1-9.
Figure 1-8 Telco 19-Inch Rack Installation—Rear Panel Forward
Figure 1-9 Telco 24-Inch Rack Installation—Rear Panel Forward
Installing in a Rack
After the brackets are secured to the chassis, you can rack-mount the chassis. Using the screws you provide, attach the chassis to the rack as shown in Figure 1-10 or Figure 1-11.

Figure 1-11 Attaching the Chassis to the 24-Inch Rack—Rear Panel Forward
CautionIf you plan to place the router on a desk or table, do not place anything on top of the router that weighs in excess of 10 pounds (4.5 kg). Excessive weight on top could damage the chassis.
Wall-Mounting the Chassis
Use the smaller brackets, for use with a 19-inch rack, to wall-mount chassis. The smaller brackets will provide the most stable position for the chassis. To wall-mount the chassis, follow these steps:
Step 1

CautionTo prevent the chassis from pulling away from the wall when cables are attached, align the brackets and screws with a vertical wall stud. (See Figure 1-13.) To ensure adequate ventilation, make sure there is clearance between the router and the wall. Mount the router as shown in Figure 1-13, placing the chassis fan and power supply at the top.
Figure 1-13 Wall-Mounting the Chassis
Making External Connections
Following are the procedures for making external connections to the different router, access server, and hub models.
Connections for Router Models
Figure 1-14 shows the rear panel of the single LAN router (the rear panel of the dual LAN router is similar), with the following connectors:

or Token Ring DB-9 (models 2502, 2504, 2513, and 2515 not shown)
or dual Ethernet AUI DB-15 (model 2514 not shown), dual Token Ring (model 2515 not shown)
or single Ethernet and Token Ring (model 2513 not shown)2

CautionTo prevent damage to the system, make certain you connect the BRI cable to the BRI connector only and not to any other RJ-45 connector. The console, auxiliary, asynchronous serial, and BRI ports all use RJ-45 connectors.

If you are installing the router in the European Community, Italy, or the United Kingdom, refer to the Cisco 2500 Series Public Network Certification publication for information about connection prerequisites and related safety warnings.
Note
Connecting the DC-Input Power Supply
This section describes the Cisco 2500 series direct current (DC) power supply specifications and wiring. This procedure covers the following information:
•
DC Power Specifications
The Cisco 2500 DC-input power supply is intended for use in DC operating environments. Table 1-1 lists the power supply specifications.
Table 1-1 Cisco 2500 DC-Input Power Supply Specifications
Power
40W, -40 to -72 VDC
Wire gauge for power connections
14 AWG1
1 AWG=American Wire Gauge.
Wiring the DC-Input Power Supply
If you ordered a Cisco 2500 series router with a DC-input power supply, follow the directions in this section for proper wiring. Figure 1-18 shows the rear of the DC-input power supply (Model 2501-DC).
Warning
Before conducting any of the following procedures, ensure that power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position.
Note
Note
Figure 1-18 Cisco 2500 Series DC-Input Power Supply—Rear View
Figure 1-19 shows the DC-input power supply terminal block. Follow these procedures for wiring the terminal block:
Step 1
Step 2
CautionDo not overtorque the terminal block captive thumbscrew or terminal block contact screws. The recommended torque is 8.2 ± 0.4 inch-lb.
CautionSecure the wires so that they will not be disturbed by casual contact. For example, secure the wires to a rack frame using tie wraps.
Step 3

Connecting to the Network
If your router has an Ethernet port, follow Step 1. If it has a Token Ring port, proceed to Step 3. If your router has both an Ethernet and Token Ring port (model 2515), start with Step 1.

Step 6
CautionMake sure that the SCSI connector on the breakout cable is securely connected to the SCSI connector on the access server. A short could occur which might damage your access server if the connection is disconnected.
Step 7
On the Cisco 2516, set the MDI/MDI-X switch to MDI-X to configure the hub as a standalone hub. Set the MDI/MDI-X switch to MDI to configure Ethernet port 6 on the hub for connecting to another hub.
Step 8
Figure 1-24 BRI Interface Port—RJ-45 Female Connector
Warning
Network hazardous voltages are accessible in the BRI cable. If you detach the BRI cable, detach the end away from the router first to avoid possible electric shock. Network hazardous voltages also are accessible on the system card in the area of the BRI port (RJ-45 connector), regardless of when power is turned off. (See Figure 1-25.)
Figure 1-25 Network Hazardous Voltage Area near the BRI Port
Step 9
CautionTo prevent damage to the system, make certain you connect the BRI cable to the BRI connector only and not to any other RJ-45 connector. The console, auxiliary, and BRI ports all use RJ-45 connectors.
Step 10
(See Figure 1-14.)Step 11
What to Do after Installing the Router Hardware
After you install the router hardware, the system is ready to be powered on and configured. For information on router software configuration, refer to the appropriate software publications. If you are installing the router in the European Community, Italy, or the United Kingdom, refer to the Cisco 2500 Public Network Certification publication that accompanied the chassis for information about connection requirements and related safety warnings.
