Connecting the AC Power Cord Wiring the DC Power Supply Where to Go Next Installing the Cisco AS5300 This chapter guides you through the installation of the Cisco AS5300 universal access server and includes the following sections: • Required Tools and Equipment •...
Warning Only trained and qualified personnel should be allowed to install or replace this equipment. Warning This equipment is intended to be grounded. Ensure that the host is connected to earth ground during normal use. Warning Incorrect connection of this or connected equipment to the general purpose outlet could result in a hazardous situation.
When installing the unit, the ground connection must always be made first and disconnected last. Warning This unit is intended for installation in restricted access areas. A restricted access area is where access can only be gained by service personnel through the use of a special tool, lock and key, or other means of security, and is controlled by the authority responsible for the location.
Rack-Mounting the Chassis This section describes how to rack-mount the chassis. The access server arrives with 19-inch rack-mount brackets and larger brackets for use with a 23- or 24-inch rack. (See .) You can also order telco rack-mount brackets (see ). The part number for telco brackets is AS52/3RM- TELCO-19"=.
• When equipment installed in a rack (particularly in an enclosed rack) fails, try operating the equipment by itself, if possible. Power OFF other equipment in the rack (and in adjacent racks) to allow the unit under test a maximum of cooling air and clean power. •...
Attaching the Brackets To install the chassis in a rack, attach the brackets in one of the following ways: • With the standard brackets on the side panels of the access server with the front panel forward or rear panel forward, as shown in and . •...
Figure 3-6 Optional Telco Bracket Installation—Rear Panel Forward Installing in a Rack After the brackets are secured to the chassis, you can rack-mount the access server. Using the screws that you provide, attach the chassis to the rack as shown in . Figure 3-7 Attaching the Chassis to the 19-Inch Rack—Rear Panel Forward...
This section describes how to connect the access server to your network. The cables required to connect the access server to a network are not provided. For ordering information, contact customer service (see the section "Cisco Connection Online" in the "Preface") or see the appendix "" for cable and port pinouts.
Note The access server arrives with all cards already installed, unless you order a card separately as a spare. Refer to the Cisco AS5300 Universal Access Server Module Installation Guide for card installation instructions.

• Use an E1 cable to connect each E1/PRI port to an E1 channel service unit (CSU) or data service unit (DSU). (See .) • Use a a serial transition cable to connect one of the four synchronous serial ports to a modem or a CSU/DSU.

A 10-position rotary switch (labeled IMP SEL) allows you to choose the number of ports that are terminated as 75-ohm unbalanced lines. The LED labeled 120 at each port indicates the input impedance of that port. If the LED is on, it indicates the impedance of the port is set to 120 ohms.

The telecommunications lines must be disconnected 1) before unplugging the main power connector and/or 2) while the housing is open. Warning The E1 interface card may only be installed in an ACA-permitted customer equipment or a Data Terminal Equipment (DTE) that is exempted from ACA's permit requirements. The customer equipment must only be housed in a cabinet that has screw-down lids to stop user access to overvoltages on the customer equipment.
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 a Modem to the Auxiliary Port To connect a modem to the auxiliary port, follow these steps: Step 1 Connect a modem to the auxiliary port on the access server using an RJ-45 rollover cable with an RJ-45-to-DB-25 adapter. The adapter provided is labeled MODEM. (See .) 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.
Connecting to the Alarm Port Do not connect to the three-pin alarm port. The alarm port is disabled. It is a future enhancement that is not supported by current versions of the system software or the feature cards. Note Connect the alarm port only to a safety extra-low voltage (SELV) source using 22 AWG, or thicker, copper wire.
Do not touch the power supply when the power cord is connected. For systems with a power switch, line voltages are present within the power supply even when the power switch is off and the power cord is connected. For systems without a power switch, line voltages are present within the power supply when the power cord is connected.
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 A readily accessible two-poled disconnect device must be incorporated in the fixed wiring. Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit.

In a DC power supply installation do not connect the -48 VDC return to chassis ground at the Cisco AS5300. A single-point ground is recommended at the power distribution rack. Step 2 Strip off a quarter of an inch (1/4 in. [0.625 cm]) of insulation on the safety ground,...

Step 3 Install the safety ground (green wire) into the terminal block ground connector and tighten the locking screw. Ensure that no bare wire is exposed. Caution Do not overtorque the terminal block contact screws. The recommended torque is 8.2 ± 0.4 inch- Step 4 Insert the +48 VDC wire into the terminal block positive connector (+) and tighten the locking screw.
When you power ON the access server for the first time, messages will begin to appear on your console screen. Proceed to the Cisco AS5300 Universal Access Server Software Configuration Guide for configuration instructions. The remainder of this guide includes reference material for...
