Setting the Chassis on a Desktop

Rack-Mounting the Chassis


Warning   

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.


Setting the Chassis on a Desktop

The location of the chassis is extremely important for proper operation. Equipment placed too close together, inadequate ventilation, and inaccessible panels can cause malfunctions and shutdowns, and can make maintenance difficult. The following information will help you to plan the location of the chassis:

Plan for access to both front and rear panels of the chassis.

Ensure that the room where the chassis operates has adequate ventilation. Remember that electrical equipment generates heat. Ambient air temperature may not cool equipment to acceptable operating temperatures without adequate ventilation.

Attach the rubber feet as shown in . Rubber feet are included in the accessory kit that shipped with your access server.

Figure 3-1 Attaching the Rubber Feet

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"=.

The following information will help you plan your equipment rack configuration:

Enclosed racks must have adequate ventilation. Ensure that the rack is not congested, because each unit generates heat. An enclosed rack should have louvered sides and a fan to provide cooling air. Heat generated by equipment near the bottom of the rack can be drawn upward into the intake ports of the equipment above.

When mounting a chassis in an open rack, ensure that the rack frame does not block the intake or exhaust ports. If the chassis is installed on slides, check the position of the chassis when it is seated in the rack.

Baffles can isolate exhaust air from intake air, which also helps to draw cooling air through the chassis. The best placement of the baffles depends on the airflow patterns in the rack, which can be found by experimenting with different configurations.

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.

Install the chassis and external devices to which it will connect in a contiguous stack.


Warning   

Before working on a chassis or working near power supplies, unplug the power cord on AC units; disconnect the power at the circuit breaker on DC units.


Required Tools and Equipment

You need the following tools and equipment to rack-mount the chassis:

Number 2 Phillips screwdriver (not included)

Connecting to the Network

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.


Warning   

To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports use both RJ-45 connectors. Use caution when connecting cables.



Note   Connect the alarm port only to a safety extra-low voltage (SELV) source using 22 AWG, or thicker, copper wire. SELV ratings are maximum 30 Volts AC (RMS), maximum 60 Volts DC, and maximum 50 VA power. The alarm port is rated for 2.0 Amps maximum current.



Warning   

Do not work on the system or connect or disconnect cables during periods of lightning activity.



Caution   
If the access server is configured with fewer than three feature cards, make sure that a blank slot cover is installed over each open slot to ensure proper airflow.


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.


Connecting to an Ethernet Network

You can connect the access server to an Ethernet network by using a straight-through RJ-45-to-RJ-45 Ethernet cable to connect the Ethernet 10BaseT or 10/100BaseT port to an Ethernet hub. (See .)

Figure 3-8 Connecting to an Ethernet Hub (10BaseT Shown)

Connecting to a WAN

You can connect the access server to a WAN in the following ways:

Use a straight-through RJ-45-to-RJ-45 cable to connect each T1/PRI port to an RJ-45 jack. (See .)

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.


Warning   

Before opening the chassis, disconnect the telephone-network cables to avoid contact with telephone-network voltages.



Warning   

Hazardous network voltages are present in WAN ports regardless of whether power to the router is OFF or ON. To avoid electric shock, use caution when working near WAN ports. When detaching cables, detach the end away from the router first.


Figure 3-9 Connecting to an RJ-45C (T1) Jack

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. If the LED is off, it indicates the impedance of the port is set to 75 ohms.

If you are connecting to a port with 75-ohm input impedance, use an RJ-45-to-75-ohm coaxial cable adapter and plug it into a port with the 120 LED off.


Warning   

This equipment is to be installed and maintained by service personnel only as defined by AS/NZS 3260 Clause 1.2.14.3 Service Personnel.



Warning   

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. The customer equipment has circuitry that may have telecommunications network voltages on them.

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.

Figure 3-13 Connecting a Modem to the Auxiliary Port

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. SELV ratings are maximum 30 Volts AC (RMS), maximum 60 Volts DC, and maximum 50 VA power. The alarm port is rated for 2.0 Amps maximum current.


Supplying Power

The access server is available with either an AC or DC power supply. You can also order a power supply as a spare if you decide later that you need a different type of power supply or the power supply fails.


Warning   

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.


Connecting the AC Power Cord

Take these steps:


Step 1 Connect one end of the power cord to the power connector on the rear panel of the access server. (See .)

Step 2 Connect the other end of the power cord to the power outlet.


Warning   

The plug-socket combination must be accessible at all times because it serves as the main disconnecting device.


Step 3 Power ON the access server.

The internal power supply fan should power on.

Figure 3-14 Connecting the AC Power Cord

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. 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   This product is intended for installation in restricted access areas and is approved for connection using 12 or 14 AWG copper conductors only. The installation must comply with all applicable codes.


Refer to and follow these steps to wire the terminal block:


Step 1 Note the orientation of the DC power supply. The power supply cord should have three wires: +48 VDC, -48 VDC, and a safety ground (green wire).


Note   For central office installations, it is recommended to use a 6 AWG green ground wire with one end connected to reliable earth. The other end of the wire should be crimped onto the double-hole lug provided in the installation pack. The lug should be secured to the mating holes on either side of the chassis with the two screws included in the accessory pack.



Warning   

The illustration shows the DC power supply terminal block. Wire the DC power supply using the appropriate wire terminations at the wiring end, as illustrated. The proper wiring sequence is ground to ground, positive to positive, and negative to negative. Note that the ground wire should always be connected first and disconnected last.



Caution   
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, +48 VDC, and -48 VDC input wires.

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-lb.

Step 4 Insert the +48 VDC wire into the terminal block positive connector (+) and tighten the locking screw. Ensure that no bare wire is exposed.

Step 5 Insert the -48 VDC wire into the terminal block negative connector (-) and tighten the locking screw. Ensure that no bare wire is exposed.

Step 6 Secure the power supply cord to the cable strain-relief clamps on the DC power supply with cable ties.


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.


Step 7 Power ON the access server.

The internal power supply fan should power on.
