Setting Up the Chassis
You can set the chassis on a desktop or install it in a rack. Use the procedure in this section that
best meets the needs of your network:
•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)
• Screws for attaching the chassis to the rack (not included)
• Rack-mount brackets

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 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
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 rollover cable and an RJ-45-to-DB-25 or RJ-45-to-
DB-9 adapter. The adapters provided are labeled TERMINAL. Other types of adapters are not
included. (See .)
For additional information on rollover cable pinouts, see the appendix "."
Step 2 Configure your terminal or PC terminal emulation software for 9600 baud, 8 data bits, no
parity, and 2 stop bits.

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.
