Setting Up the Chassis

You can set the chassis on a desktop, install it in a rack, or other flat surface. Use the procedure in this section that best fits the needs of your network.

Setting the Chassis on a Desktop

Before setting the access server on a desktop, shelf, or other flat, secure surface, the follow these steps to install the rubber feet:

Step 1 Locate the rubber feet on the black adhesive strip that shipped with the chassis.

Step 2 Place the access server 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 at each corner of the chassis bottom.

Step 4 Place the access server right-side up on a flat, smooth, secure surface.

Caution Do not place anything on top of the access server that weighs more than 10 pounds (4.5 kg). Excessive weight could damage the chassis.

Rack-Mounting 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 23-inch or 24-inch rack. The brackets are similar to those shown in Figure 3-1.

Connecting to the Network

This section describes how to connect the access server to your network using the Ethernet (AUI) or dual T1 Primary Rate Interface (PRI) cards.

The cables required to connect the access server to a network are not provided. For ordering information, contact customer service or see the appendix "Cabling Specifications for the Universal Access Server" for cable and port pinouts.

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 Regulatory Compliance and Safety Information document that accompanied the access server.)

Connecting to an Ethernet Network

The access server uses an Ethernet AUI to connect to your Ethernet network. Connect the access server to your Ethernet network with an Ethernet transition cable from the Ethernet AUI port to an Ethernet transceiver. See Figure 3-10.

Note If your Ethernet connection requires jackscrews, remove the slide-latch connector from the AUI connector and attach the jackscrews provided.

Figure 3-10 : Connecting to an Ethernet Transceiver

Connecting to a WAN

Follow these steps and use the illustrations in this section to connect the access server through the PRI card to your WAN:

Step 1 Use a straight-through RJ-48-to-RJ-48 cable to connect the RJ-48C port to an RJ-48C jack. See Figure 3-11.

Figure 3-11 : Connecting the T1 PRI Card to an RJ-48C (T1) Jack

Step 2 Use a serial transition cable to connect the synchronous serial port to a modem or channel service unit/data service unit (CSU/DSU). See Figure 3-12.

Step 3 If the access server is configured with fewer than three feature cards, install a blank slot cover over each open slot to ensure proper airflow.

Figure 3-12 : Connecting Synchronous Serial Cables

Connecting the Console Terminal and Modem

Use the console terminal for local administrative access to the access server. You can only connect a terminal to the console port. You can use the auxiliary port to connect a terminal or a modem for remote access to the access server.

Connecting to the Console Port

Follow these steps to connect a terminal (an ASCII terminal or a PC running terminal emulation software) to the console port on the access server:

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 adapter provided by Cisco Systems is labeled Terminal. Other types of adapters are not included. See Figure 3-13.

For additional information on roll-over cable pinouts, see the appendix "Cabling Specifications for the Universal Access Server."

Step 2 Configure your terminal or PC terminal emulation software for 9600 baud, 8 data bits, no parity, and 2 stop bits.

Figure 3-13 : Connecting the Console Terminal

Connecting a Modem to the Auxiliary Port

Follow these steps to connect a modem to the auxiliary port on the access server:

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 3-14.

Figure 3-14 : Connecting a Modem to the Auxiliary Port

Step 2 Make sure that your modem and the auxiliary port on the access server 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.

Wiring the DC Power Supply

If you ordered the access server with a DC power supply, follow the procedure 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 Regulatory Compliance and Safety Information document that accompanied the access server.)

Note This product is intended for installation in restricted access areas and is approved for connection using minimum 14 AWG copper conductors only. The installation must comply with all applicable codes.

Figure 3-15 shows the DC power supply terminal block. Follow these steps to wire the terminal block:

Step 1 Remove the terminal block cover plate.

Step 2 Attach the appropriate lugs at the wire end of the power supply cord.

Step 3 Wire the DC power supply cord to the terminal block, as shown in Figure 3-15.

Step 4 Secure the power supply cord to the cable strain-relief clamps on the DC power supply with cable ties.

Step 5 Install the terminal block cover plate.

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 Regulatory Compliance and Safety Information document that accompanied the access server.)

Figure 3-15 : DC Power Supply Connections

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 Regulatory Compliance and Safety Information document that accompanied the access server.)

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 Regulatory Compliance and Safety Information document that accompanied the access server.)
