Compliance Information
and TV
Radio
The Model 3120 generates and uses radio frequency energy, and if not installed and used properly—that is, in
strict accordance with the manufacturer's instructions—may cause interference to radio and television reception. The Model 3120 has been tested and found to comply with the limits for a Class A computing device in
accordance with the specifications in Subpart B of Part 15 of FCC rules, which are designed to provide reasonable protection from such interference in a commercial installation. However, there is no guarantee that interference will not occur in a particular installation. If the Model 3120 causes interference to radio or television
reception, which can be determined by disconnecting the cables, try to correct the interference by one or more
of the following measures: moving the computing equipment away from the receiver, re-orienting the receiving
antenna, and/or plugging the receiving equipment into a different AC outlet (such that the computing equipment and receiver are on different branches).
Interference
Industry Canada Notice
The Canadian Department of Communications label identifies certified equipment. This certification means
that the equipment meets certain telecommunications network protective, operational and safety requirements. The Department does not guarantee the equipment will operate to the user's satisfaction. Before installing this equipment, users should ensure that it is permissible to be connected to the facilities of the local

– “RAS chassis installation”—describes installing the RAS on a flat surface or in a standard 19–inch rack.
– “Cable installation” on page 21—describes installing the power and network interface cables
– “Completing the hardware installation” on page 25—describes testing the RAS hardware to verify that it is
ready for software configuration.
Unpacking the Model 3120 RAS
Inspect the shipping carton for external damage. Note any damage before removing the container contents.
Report equipment damage to the shipping carrier immediately for claim purposes. Save all packing materials in
case you need to return an item to the factory for servicing.
The RAS comes with the following items:
– The 3120 Series Remote Access Server (RAS)
– A DB-9-to-RJ-45 (EIA-561) cable, 10 foot (3 meters)
– Control port interface cable, 10 foot (3 meters), standard CAT-5 cable
– Two WAN connection cables, 10 foot (3 meters) each
– Rack mounting kit with rack ears and mounting hardware
– CD-ROM containing product literature and the following documentation:
- Access Server Administrator’s Reference Guide
- Model 3120 RAS Getting Started Guide
Note Power cables are shipped separately from the Model 3120 RAS.
RAS chassis installation
Do the following:
1. If you have not done so already, remove the RAS from its shipping container.
Note The RAS should be placed as close as possible to the termination jack
provided by the Telco. Avoid installing the RAS in a location where
the power cords or network interface cables could be accidentally disconnected. The location should be well ventilated. Do not block the
RAS’s cooling vents.
2. If you are installing the RAS in a 19-inch rack, go to step 3. Otherwise, place the RAS at the desired loca-
tion, then go to “Cable installation” on page 21.
3. Install the rack mounting ears onto the RAS using the mounting hardware provided.

5. Secure the RAS in position with the mounting screws.
Cable installation
This section describes installing the power, ground, and network interface cables.
The RAS power supply can be configured for 115 or 230 VAC
operation. By default, the 3120/120 RAS is set to 230 VAC
and the 3120/96 is set to 115 VAC. If you need to change the
voltage setting for your power supplies, contact your Patton distributor or Patton Electronics technical support.
Verify that the proper voltage is present before plugging the
power cord into the receptacle. Failure to do so could result in
equipment damage.
Installing the power cables—AC power supply
This section describes installing the female end of the power cables into the IEC-320 connectors on the RAS.
Do not connect the male end of the power cables to the power outlet at this time. Do the following:
1. Install a power cable into an IEC-320 connector (see figure 5).
Note The AC main socket outlet must be located within 10 feet (3 meters)
of the equipment and be easily accessible.
Figure 5. IEC-320 connector and grounding stud locations
To avoid the risk of injury from electric shock, the power cords connected to
the IEC-320 connectors must be grounded power cords.

of the terminal block. Make sure that all strands of the wire are captured and that there is no exposed wire.
4. Repeat steps 1 through 3 to install the remaining DC power connection.
Grounding the Model 3120—AC and DC Power Supplies
Do the following:
1. Assemble a ground wire using #10 AWG wire with green-colored insulation and two ring terminals. Make
the wire long enough to reach one of the following ground sources:
– The building ground rod (generally located at the site’s main service entrance)
– A sprinkler system pipe
– A cold-water pipe
– Building structural steel
To avoid the risk of personal injury, the distance between ground and the
equipment rack must not exceed the distance specified in either local electrical
codes or the National Electrical Code.
2. Install the ground wire between the grounding stud (see figure 6) and the grounding source.
Connecting the Ethernet ports
The RAS has two 10/100 Ethernet interfaces for connection to your LAN (see figure 8). The Ethernet port will
autosense the correct speed of the local LAN and automatically negotiate half- or full-duplex operation. This
section describes connecting the RAS to the Ethernet LAN via an Ethernet hub, switch, or workstation.

3 • Configuring the RAS for operation Model 3120 RAS Getting Started Guide
Introduction
This chapter contains the following procedures for configuring the Model 3120 Remote Access Server for
operation:
• “Configuration prerequisites”—lists the items you need to have on hand before configuring the RAS.
• “Preparing the RAS for configuration”—describes setting up the RAS IP address and netmask parameters.
• “Configuring the RAS with a Web browser” on page 32—describes installing the power and network inter-
face cables
• “Saving your configuration” on page 48—tells you how to save the configuration settings.
• “Completing the installation” on page 50—describes testing the RAS to verify that it is fully operational
Configuration prerequisites
You will need the following to configure the RAS:
• A PC with a serial port and a VT-100 terminal program
• A PC with an Ethernet port and a WWW browser (Microsoft Internet Explorer or Netscape Communica-
tor) connected to the remote access server’s local LAN
• The IP address and subnet mask for the RAS’s Ethernet port
• A range of IP addresses to be assigned to the dial-in users (IP pool)
• The IP addresses of the domain name servers (DNS)
• The IP address of the default gateway
Note Before installing the RAS, you will need the following information
from your local telephone company (telco):
• The line type and encoding of the T1/E1 line
• The signalling of the E1 (ISDN or MFCR2) line or the signalling
of the T1 line. If the signalling for E1 is MFCR2, you will need the
number of digits the telco will send over the line for the called
number and the calling number
• The voice channels that are active on the T1/E1 line
Preparing the RAS for configuration
Before the RAS can be configured the IP address and the netmask needs to be set up. This setup is done
through the RS-232 CONFIG port on the RAS.
1. If you have not done so already, install the supplied DB-9-to-RJ-45 cable between the RAS RS-232 port
(see figure 8 on page 23) and an open serial port on your computer.

Page 37
Model 3120 RAS Getting Started Guide 3 • Configuring the RAS for operation
From the Home page, the following actions can be performed:
• Record Current Configuration—clicking on this button (figure 20) causes the current configuration to be
stored in FLASH memory. Any changes made to the RAS configuration are stored in non-volatile RAM
first. This allows the user to set the box up with a working configuration before committing it to FLASH.
Configuration changes become permanent when you select Record Current Configuration. You will lose all
changes not stored to FLASH the next time the RAS is re-booted.
Figure 20. Immediate Actions buttons
• Hard Reset—this button (figure 20) causes the RAS to perform a cold restart. When you select Hard Reset,
the RAS confirms that you want to execute this command. Then, the RAS will disconnect all current sessions, re-initialize the interfaces, and re-load configuration parameters from FLASH.
• Set Factory Default Configuration—this button (figure 20) clears out the configuration in FLASH and
loads the factory default parameters into FLASH memory. The factory default settings will not execute on
the RAS until it is re-booted.
Note Set Factory Default Configuration (figure 20) will delete any routing
information, the RAS’s Ethernet IP address, and any other site specific settings made for your particular installation. You will have to reenter the RAS’s Ethernet IP address and netmask using the front
panel control port in order to use the HTTP/HTML Management pages.

Introduction
This chapter describes how to start or power-down the RAS.
Activating the RAS
Once the RAS has been installed, no operator action is required under normal conditions; the RAS is designed
for unattended operation. The RAS does not have a power switch. When either power supply is connected to
power, the RAS will immediately begin its boot-up cycle. However, both power supplies must be connected to
power for the redundancy feature to work.
When power is applied to the RAS the following should occur:
1. The POWER LED illuminates.
2. The Link 1 Frame LED illuminates, indicating that the RAS is synchronizing with the T1/E1/PRI signal.
3. After 5 seconds, the Link A Error LED flashes, indicating that the RAS is satisfied with the quality of the
T1/E1/PRI signal.
4. After 10 seconds, the Link A Error LED extinguishes, indicating that the RAS is satisfied with the network
signal and that the link is ready for use.
5. There are two LEDs on each RAS 10/100 Ethernet port: a green LED that indicates line speed, and a yel-
low LED that indicates link status and activity.
The yellow LED is either flashing yellow (meaning that packets are being received at the Ethernet port) or
solid yellow (meaning that the link is valid but no packets are being received).
The green LED is either lit (indicating 100 Mbps operation) or off (indicating 10 Mbps operation).
Note The green LED reflects the speed of the last valid Ethernet
connection.
The RAS is operational.
De-activating the RAS
Perform the following procedure to deactivate the RAS.
1. Disconnect the male ends of both power cords from the power distribution strip or to a wall outlet.
2. Verify that the POWER LED extinguishes.

1. At the malfunctioning power supply, rotate the power cable retaining clip (see figure 47) so it is no longer
attached to the power cord.
2. Disconnect the power cable plug from the malfunctioning power supply.
3. Using a flat-tip screwdriver, loosen the two captive fasteners (see figure 47) enough so they are no longer
connecting the power supply to the RAS chassis.

Do not use the power cable retainer clip as a handle when
removing the power supply from the RAS chassis. Failing to comply with this caution could result in damage to the power supply.

Warranty Service and Returned Merchandise Authorizations (RMAs)
Patton Electronics is an ISO-9001 certified manufacturer and our products are carefully tested before shipment. All of our products are backed by a comprehensive warranty program.
Note If you purchased your equipment from a Patton Electronics reseller,
ask your reseller how you should proceed with warranty service. It is
often more convenient for you to work with your local reseller to
obtain a replacement. Patton services our products no matter how
you acquired them.
Warranty coverage
Our products are under warranty to be free from defects, and we will, at our option, repair or replace the product should it fail within one year from the first date of shipment. Our warranty is limited to defects in workmanship or materials, and does not cover customer damage, lightning or power surge damage, abuse, or
unauthorized modification.
Out-of-warranty service
Patton services what we sell, no matter how you acquired it, including malfunctioning products that are no
longer under warranty. Our products have a flat fee for repairs. Units damaged by lightning or other catastrophes may require replacement.
Returns for credit
Customer satisfaction is important to us, therefore any product may be returned with authorization within 30
days from the shipment date for a full credit of the purchase price. If you have ordered the wrong equipment or
you are dissatisfied in any way, please contact us to request an RMA number to accept your return. Patton is
not responsible for equipment returned without a Return Authorization.
