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.
Required Tools and Equipment
The following items are included with the access server:
• 19- and 24-inch rack-mount brackets
• Rubber feet for desktop installation
• RJ-45-to-DB-9 female DTE adapter (labeled TERMINAL)
• RJ-45-to-DB-25 female DTE adapter (labeled TERMINAL)
• RJ-45-to-DB-25 male DCE adapter (labeled MODEM)
• RJ-45-to-RJ-45 rollover console cable
• ESD-preventive wrist strap
• Nylon cable tie
• Cable tie holder
• Grounding lug
You might need the following equipment, which is not included:
• Four screws for installing the access server in a rack
• Straight-through RJ-45-to-RJ-45 cable for an Ethernet connection
• Ethernet hub or PC with a network interface card for Ethernet LAN connections
• Up to four straight-through RJ-45-to-RJ-45 cables for T1 connections
• Up to four E1 cables for E1 connections
• PC running terminal emulation software for local administrative access
• Modem for remote administrative access
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
Figure 3-2 Standard Rack-Mount Brackets
Figure 3-3 Telco Rack-Mount Bracket
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 .
• With the telco brackets on the side panels of the access server with the rear panel forward, as
shown in .
Note Although the installations show the 19-inch brackets, the procedure is the same for the
larger brackets.
Figure 3-4 Standard Bracket Installation—Front Panel Forward
Figure 3-5 Standard Bracket Installation—Rear Panel Forward
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
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.
