This chapter guides you through the installation of the Cisco 2524 and Cisco 2525 routers and includes the following sections:
 | Warning Only trained and qualified personnel should be allowed to install or replace this equipment. (To see translated versions of this warning, refer to the appendix "Translated Safety Warnings.") |
Following are the tools and parts required to install the router:
In addition, you might need the following external equipment:
You can set the chassis on a desktop, install it in a rack, or mount it on a wall or other flat surface. Use the procedure in this section that best fits the needs of your network.
Before setting the router on a desktop, shelf, or other flat, secure surface, perform the following steps to install the rubber feet:
Step 1 Locate the rubber feet on the black adhesive strip that shipped with the chassis. (See Figure 3-1.)
Step 2 Place the router upside down on a smooth, flat surface.
Step 3 Peel off the rubber feet from the black adhesive strip and place them adhesive-side down onto the five round, recessed areas on the bottom of the chassis, as shown in Figure 3-2.
Step 4 Place the router right-side up on a flat, smooth, secure surface.
 | Caution Do not place anything on top of the router that weighs more than 10 pounds (4.5 kg). Excessive weight on top could damage the chassis. |
This section describes the procedures for rack-mounting the chassis. The chassis comes 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 3-3.
To install the chassis in a rack with the front panel forward, attach the brackets as shown in Figure 3-4 or Figure 3-5.
To install the chassis in a rack with the rear panel forward, attach the brackets as shown in Figure 3-6 or Figure 3-7.
To install the chassis in a center-mount telco rack, attach the brackets as shown in Figure 3-8 or Figure 3-9.
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 3-10 or Figure 3-11.
Use the smaller brackets (for use with a 19-inch rack) to wall-mount the chassis. The smaller brackets provide the most stable position for the chassis.
Take the following steps to wall-mount the chassis:
Step 1 Attach the brackets as shown in Figure 3-12.
Step 2 Attach the chassis assembly to the wall as shown in Figure 3-13, using screws and anchors that you provide. We recommend the following:
| Caution To 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 3-13.) To ensure adequate ventilation, make sure there is clearance between the router and the wall. |
The Cisco 2524 router offers an optional direct current (DC) power supply (not available with the Cisco 2525 router). This section describes the DC power supply specifications and wiring.
| Warning This unit is intended for installation in restricted access areas. (To see translated versions of the warning, refer to the appendix "Translated Safety Warnings.") |
The DC power supply is intended for use in DC operating environments. Table 3-1 lists the power supply specifications.
| Description | Design Specification |
|---|---|
| Power (input) | 40W, -40 to -72 VDC |
| Wire gauge for power connections | 14 AWG1 |
If you ordered a Cisco 2524 router with a DC power supply, follow the directions in this section to wire the terminal block.
| Warning Before performing 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. (To see translated versions of this warning, refer to the appendix "Translated Safety Warnings.") |
Figure 3-14 shows the DC power supply terminal block. Take the following steps to wire the terminal block:
Step 1 Attach the appropriate lugs at the wire end of the power supply cord.
Step 2 Wire the DC power supply to the terminal block, as shown in Figure 3-14.
| Warning The illustration shows the DC power supply terminal block. Wire the DC power supply using the appropriate lugs at the wiring end, as illustrated. The proper wiring sequence is ground to ground, positive to positive (line to L), and negative to negative (neutral to N). Note that the ground wire should always be connected first and disconnected last. (To see translated versions of this warning, refer to the appendix "Translated Safety Warnings.") |
| Warning When stranded wiring is required, use approved wiring terminations, such as closed-loop or spade-type with upturned lugs. These terminations should be the appropriate size for the wires and should clamp both the insulation and conductor. (To see translated versions of this warning, refer to the appendix "Translated Safety Warnings.") |
| Caution Do not overtorque the terminal block captive thumbscrew or terminal block contact screws. The recommended torque is 8.2 ± 0.4 inch-lb. |
| Warning After wiring the DC power supply, remove the tape from the circuit breaker switch handle and reinstate power by moving the handle of the circuit breaker to the ON position. (To see translated versions of this warning, refer to the appendix "Translated Safety Warnings.") |
This section explains how to connect the router to your network, using the Ethernet (AUI or 10BaseT) or Token Ring (STP or UTP) ports or the WAN modules.
| Warning Do not work on the system or connect or disconnect cables during periods of lightning activity. (To see translated versions of this warning, refer to the appendix "Translated Safety Warnings.") |
If you have a Cisco 2524 router, it includes both an Ethernet AUI port and a 10BaseT port. To connect your router to an Ethernet network, you can use either the Ethernet AUI or 10BaseT port, but not both. The first port connected will work. (If you attempt to use both ports, only the 10BaseT port will work.)
You can connect the router to your Ethernet network in one of the following ways:
If you have a Cisco 2524 router, you can connect the router to your Token Ring network in one of the following ways:
Although the illustrations in this section show the Cisco 2524 router, the procedures are the same for both the Cisco 2524 and Cisco 2525 routers.
| Warning Do not work on the system or connect or disconnect cables during periods of lightning activity. (To see translated versions of this warning, refer to the appendix "Translated Safety Warnings.") |
Take the following steps to connect the router to your WAN:
Step 1 If you have a 2-wire switched 56-kbps module, use a straight-through RJ-11-to-RJ-11 cable to connect the RJ-11 port to an RJ-11 jack. (See Figure 3-20.)
Step 2 If you have a 4-wire 56/64-kbps DSU/CSU module, use a straight-through RJ-48S-to-RJ-48S cable to connect the RJ-48S port to an RJ-48S jack. (See Figure 3-21.)
Step 3 If you have a fractional T1/T1 DSU/CSU module, use a straight-through RJ-48C-to-RJ-48C cable to connect the RJ-48C port to an RJ-48C jack. (See Figure 3-22.)
Step 4 If you have a synchronous serial module, use a serial transition cable to connect the synchronous serial port to a modem or DSU/CSU. (See Figure 3-23.)
Step 5 If you have an ISDN BRI module (without an integrated NT1 device), use a straight-through RJ-45-to-RJ-45 cable to connect the ISDN BRI (RJ-45) port to an NT1 device. (See Figure 3-24.)
Step 6 If you have an ISDN BRI module with an integrated NT1 device, use a straight-through RJ-45-to-RJ-45 cable to connect the ISDN BRI (RJ-45) port to an RJ-45 or RJ-11 jack. (See Figure 3-25.)
Step 7 If the router is configured with fewer than three WAN modules, install a blank slot cover over each open slot to ensure proper airflow.
Step 8 Using an M 3.5 thread-forming screw (not included), attach a ground wire to the protective grounding terminal on the rear panel of the chassis.
Step 9 Connect the power cable to the router and the power source.
You use the console terminal for local administrative access to the router. You can connect only a terminal to the console port. You can use the auxiliary port with a terminal or a modem for remote access to the router.
Take the following steps to connect a terminal (an ASCII terminal or a PC running terminal emulation software) to the console port on the router:
Step 1 Connect the terminal using an RJ-45 roll-over cable and an RJ-45-to-DB-25 or RJ-45-to-DB-9 adapter. The adapters provided by Cisco Systems are labeled Terminal. Other types of adapters are not included. (See Figure 3-26.)
Additional information on roll-over cable pinouts is provided in the appendix "Cabling Specifications for the Cisco 2524 and Cisco 2525 Routers."
Step 2 Configure your terminal or PC terminal emulation software for 9600 baud, 8 data bits, no parity, and 2 stop bits.
Take the following steps to connect a modem to the auxiliary port on the router:
Step 1 Connect a modem to the auxiliary port using an RJ-45 roll-over cable with an RJ-45-to-DB-25 or RJ-45-to-DB-9 adapter. The adapter provided by Cisco Systems is labeled Modem. (See Figure 3-27.)
Step 2 Make sure that your modem and the auxiliary port on the router are configured for the same transmission speed (38400 baud is typical) and hardware flow control with Data Carrier Detect (DCD) and Data Terminal Ready (DTR) operations.
After you have installed the router, proceed to the chapter "Configuring the Cisco 2524 and Cisco 2525 Routers" for software configuration information.
