2. Introduction
NOTE
This manual is intended to help you get your Remote Access Concentrator up and
running. It isn’t a detailed reference on the Concentrator’s operation; for more
complete information, use a standard browser to page through the HTML
documentation included on CD with the Concentrator. Also, you might want to check
our Black Box Web site (www.blackbox.com) for material that might be more up-to-
date than what you received, including software or firmware updates, updated MIBs,
and revised HTML documentation.
Enterprises seeking increased productivity and communication are extending dial-up access to their
telecommuting employees and business partners, and service providers are searching for ways to differentiate
their dial-up services to retain existing customers and attract new ones.
But this expansion in access is creating new challenges in the areas of security, accounting, and network
management. Our T1 and E1 Remote Access Concentrators (the LRA3000 series of product codes) directly
address these challenges by delivering the lowest-cost dial solutions with support built in for using RADIUS
for remote device authentication.
The Concentrators support high-density ISDN/V.90 concentration of dial-up traffic in a compact, rack-
mountable form factor. The Concentrators’ architecture supports universal dial access (ISDN or modem) on
every port, yielding excellent price/performance in a slender design that’s only 1U (1.8", 4.4 cm) high. Both
T1 and E1 versions are available, supporting two ISDN Primary Rate Interfaces (PRIs) and either 48 (T1)
or 60 (E1) DS0 connections; the DS0s can be any combination of V.90 (56K) modem and ISDN calls.
All Concentrators have redundant power supplies for added protection in mission-critical applications.
We also offer Connection Services Manager (CSM) software (our product code LRA300SW) for use with the
Concentrators. It performs remote device authentication, supports robust connection management, and gives
you real-time control over remote user authentication, policy definitions, and accounting from a centralized
server. More information about CSM is available in the HTML documentation on the CD that came with
your Concentrator.
The table below summarizes each Concentrator model’s options.
Model WAN Telco Interface(s) Number of V.90
Access Digital Modem Ports
LRA3000A T1 Dual ISDN T1/PRI 48
LRA3001A E1 Single ISDN E1/PRI 30
LRA3002A T1 Single ISDN T1/PRI 24
LRA3003A E1 Dual ISDN E1/PRI 60
NOTE
The T1 models support ISDN Primary Rate Interface (PRI) in Canada, the United
States, and Japan. The E1 models support ISDN Primary Rate Interface (PRI) in
Europe, the Asia-Pacific region (excluding Japan), and Latin America.

3.2 Arranging ISDN Service
Before you install your Remote Access Concentrator, we recommend that you contact your telco or service
provider and arrange for ISDN service compatible with the Concentrator:
1. Make sure that they use a type of ISDN central-office switch that the Concentrator supports.
2. Order an ISDN PRI line if you haven’t done so already.
3. Ask them for the ISDN line’s phone number, any prefix necessary for dialing, and the specs for line
encoding, framing, and (for T1 models) the T1 LBO.
For more details, see the “ISDN Line Ordering,” “ISDN PRI Line Information,” and “Telephone Switch
Support” sections in the Concentrator’s HTML documentation.

3.3 Setting the Pinout Switch for Your WAN Interface (T1 Models Only)
The T1 models of the Remote Access Concentrator have a PINOUT switch on their front panels. This switch
allows you to make WAN-interface adjustments based upon country of usage for the Concentrator’s WIDE
AREA 1 port. (For instructions on connecting cables to this port, see Section 3.6.3.) For North American
installations, this switch should be set to the left (the default setting). For use in Japan, this switch should
be set to the right. The switch positions translate to the following WAN-connector pinout settings:
Switch set to the left for use in North America:
pin number 1245
polarity +–+–
direction receive receive transmit transmit
Switch set to the right for use in Japan:
pin number 3456
polarity ++––
direction transmit receive receive transmit
NOTE
As stated above, the PINOUT switch adjusts the pinout setting for the WIDE AREA 1
port only. The default pinout for both ports (WIDE AREA 1 and WIDE AREA 2) is for
North American use. If the LRA3000A or LRA3002A is used in Japan, a ModTap™
adapter is required for the WIDE AREA 2 port to have a correct pinout.
E1 models of the Concentrator don’t have a PINOUT switch; they use this unchangeable, international-
standard WAN-connector pinout:
pin number 1245
polarity +–+–
direction receive receive transmit transmit

3.4 Placement
Installation sites must be within reach of the network cabling and must meet the following requirements:
• A properly grounded AC power receptacle must be within 7 feet (2.1 m) of the location.
• Temperatures at the installation site must remain between 32 and 104˚F (0 and 40˚C), with fluctuations of
less than 18˚F (10˚C) per hour.
• If you are placing the Concentrator on a shelf, the shelf must be able to firmly support 13 lb. (5.9 kg) of
static weight for each Concentrator on the shelf.
• If you are placing the Concentrator in a rack, there must be at least two inches (5 cm) of clearance on each
side of and behind the Concentrator for adequate ventilation.
3.5 Rackmounting (Optional)
CAUTION!
Before installing the Concentrator in a rack, make sure that the rack can hold the
Concentrator securely without toppling, warping, breaking, etc. Otherwise, personal
injury and equipment damage might result.
Do not use screws other than those included with the Concentrator’s Rackmount
Kit to attach the Kit’s rackmount brackets to the Concentrator’s chassis. Wrong-sized
screws can cause electrical shorts and can physically damage the Concentrator.
To mount a Remote Access Concentrator in a 19" rack, you’ll need to attach the brackets from its included
rackmount kit to the Concentrator, then attach the bracketed assembly to your rack. You’ll need both a flathead
and a Phillips screwdriver to do this.
Take these steps:
1. Decide which way you want the Concentrator to face. The standard installation is with the front of the
Concentrator facing the front of the rack; the rest of the directions in this section assume that orientation.
But you can install the Concentrator with its rear panel facing the front of the rack instead. If you do so,
you’ll have to install the brackets upside down, so that they screw onto the bottom edge of the
Concentrator’s side. You’ll also have to substitute “rear of the Concentrator” for “front of the
Concentrator” in the following steps.

2. With the Concentrator’s faceplate (the front of the unit) towards you, take the Rackmount Kit’s brackets
and place one on either side of the Concentrator, so that the front end of each bracket lines up with the
faceplate.
3. There are slots in each side of the Concentrator that are made to accept the brackets’ rear flanges, as
shown below. Swing the front of each bracket outward, insert the flanges in these slots, and swing the front
back in. (If, after you do this, the front of a bracket doesn’t line up with the Concentrator’s faceplate, or
the screwholes along the top of the side a bracket don’t line up with the screwholes on the side of the
Concentrator’s chassis, swing the bracket back out and adjust how the flanges are seated in the slots.)
4. Using the four included 6⁄32 x 1⁄4-inch flathead screws, attach each bracket to the Concentrator along the top
of the Concentrator’s chassis, as shown below.

3.6 Making Cable Connections
3.6.1 CONSOLE (ASYNC) CONNECTIONS
The Remote Access Concentrator’s RJ-45 female RS-232 console port (labeled ASYNC) is the gateway to the
Concentrator’s local management (configuration) utility. It’s proprietarily pinned out this way:
Pin Function
1 Transmit Data (TD)
2 Carrier Detect (CD)
3 Data Set Ready (DSR)
4 Receive Data (RD)
5 Signal Ground (SGND)
6 Data Terminal Ready (DTR)
7 Request To Send (RTS)
8 Clear to Send (CTS)
(Refer to the Concentrator’s HTML documentation for complete information about this port and its two
associated LEDs.)
To attach a console to this port, use the included RJ-45 male-to-male console cable to make the following
connection:
1. Plug one end of the cable into the Concentrator’s console (ASYNC) port.
2. Plug the other end of the cable into the RJ-45 to DB9 adapter that’s included with the Concentrator in its
“console cabling kit.”
3. Plug the adapter into the serial port of a terminal or of a PC running a communications package that can
do VT100™ emulation.
