About this guide
This guide describes installing and configuring a Patton Electronics Model 2960/2996 Remote Access Server
(RAS). By the time you are finished with this guide, your RAS will be receiving calls and transferring data. The
instructions in this guide are based on the following assumptions:
•The RAS will connect to a T1, E1, or PRI line
•Callers will dial-in and connect with a V.90/K56Flex/V.34 or ISDN modem using PPP
•There is a LAN connected to the Ethernet port of the RAS
Audience
This guide is intended for the following users:
•Operators
•Installers
•Maintenance technicians
Structure
This guide contains the following chapters and appendices:
•Chapter 1 describes the RAS
•Chapter 2 describes installing the RAS hardware
•Chapter 3 describes configuring the RAS for use
•Chapter 4 details how to power up and deactivate the RAS
•Chapter 5 contains troubleshooting and maintenance information
•Chapter 6 contains information on contacting Patton technical support for assistance
For best results, read the contents of this guide before you install the RAS.

Model 2960/2996 Remote Access Server overview
The Model 2960/2996 is a central site remote access server with integrated modems which terminate dial-up
analog and digital users. The Model 2960 RAS combines 16, 24, 30, 48, 60 or 72 ports—the 2996 RAS com-
bines 96 or 120—analog and digital modems, RAS software, a 10/100 Ethernet port, IP Routing, Frame
Relay/PPP forwarding, and four T1/E1 WAN ports.
The 2960/2996 RAS simultaneously consolidates analog modem and digital ISDN remote access connections
(over PSTN digital trunks) using a completely digital approach. Up to four T1/E1/PRI ports provide PSTN
and/or PABX connectivity and terminate up to 48/60 (Model 2960) or 96/120 (Model 2996) analog modem
or digitalISDN calls within a single chassis. The Model 2960/2996incorporateschannel bank, terminal server,
router and modem functionality in a self-contained, compact package.

Hardware overview
The Model 2960/2996 RAS is a fully integrated remote access server for central site concentration of analog
and digital modem calls. The RAS (see figure 2) comprises a 1U-high 17-inch wide chassis that contains a
motherboard and two dual-redundant power supplies. A full set of LEDs are present on the chassis front panel,
while connections for WAN, LAN, and control ports are present on the rear of the chassis. Two IEC-320
receptacles provide for AC power input. Optional DC power supplies with 32 to 72 VDC are available.

WAN
The RAS includes four WAN ports, each of which is software-selectable for T1, E1 or PRI operation. These
WAN ports are provided via balanced RJ-48C interfaces. They also include:
•Built-in T1/E1 CSU/DSU
•T1 1.544 Mbps with: D4 or ESF framing, AMI or B8ZS, FCC part 68 compliant
•E1 2.048 Mbps with: Double frame or CRC4 framing, AMI/HDB3, CTR-4, and CTR-12 compliant
LAN
The 10/100-Mbps Ethernet LAN port is presented on an RJ-45 connector with an auto-sensing/full-duplex
10Base-T or 100Base-T interface. It also includes:
•100Base-TX half-/full-duplex operation (100 + 100)
•10Base-T half-/full-duplex operation (10 + 10)
•Auto detection and fallback
•10/100 Mbps link and status indicators

Introduction
This chapter contains the following procedures for installing the Model 2960/2996 RAS:
•“Unpacking the Model 2960/2996 RAS”—lists the contents of the RAS shipping container
•“RAS chassis installation”—describes installing the RAS on a flat surface or in a standard 19–inch rack.
•“Cable installation” on page 19—describes installing the power and network interface cables
•“Completing the hardware installation” on page 22—describes testing the RAS hardware to verify that it is
ready for software configuration.
Unpacking the Model 2960/2996 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 2960/2996 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:

Note Power cables are shipped separately from the Model 2960/2996 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 dis-
connected. 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 19.
3. Install the rack mounting ears onto the RAS using the mounting hardware provided.
4. Place the RAS at the desired position in the rack.
