Chapter 1 - Installing and Accessing the REX2
2 Campus-REX2 RS Interface Card User Manual
The Campus-REX2 can be installed into either a Campus-Star chassis
(paired with a Campus-RS or -HRS Line Unit) or into a Campus-RS or -HRS
desktop unit. The , installed into either, provides one end of a High-bit-rate
Digital Subscriber Line (HDSL) transmission system. When connected to
another Campus-RS, Campus-HRS, Campus-T1®, Campus-768®, or
Campus-E1® desktop unit or a line unit in another chassis, the Campus
systemtransportsdigitizedvoice, data, and videosignalsover existingcopper
wire at an HDSL rate specified by the user from a range of rates up to 4.608
Mbps.
When the Campus-REX2 is installed in a Campus-HRS desktop unit or with
a Campus-HRS line unit (or older), only T1, E1, and 768 Mbps data rates are
supported.
INSTALLING THE CAMPUS-REX2
The following sections describe how to install the Campus-REX2 RS
Interface Card into either a:
•Campus desktop unit on page 1-3
•Campus-Star chassis on page 1-4
For information about compatibility between the Campus-REX2 and other
Campus products, refer to “Product Compatibility” on page 136.
For information about products that comprise a Campus system, refer to
“Composition of a Campus-RS System” on page 120.
Ensure that the Campus-REX2 is installed into a Campus-RS
or Campus-HRS desktop unit or into a Campus-Star chassis
with a Campus-RS or Campus-HRS line unit only. The
Campus-REX2 will not operate if it is installed in an earlier
version of these Campus products.
Ensure that you read important information on surge
protection for HDSL lineinstallation in the line unit or desktop
unit manual before installing the Campus-REX2 interface
card.

Campus-REX2 RS Interface Card User Manual 3
Installing into a Desktop Unit
Install the Campus-REX2 interface card into a Campus-RS or Campus-HRS
desktop unit before you install the desktop unit (install power and HDSL
cables). Install the Campus-RS desktop unit using the instructions in the
Campus-RS Desktop Unit User Manual.
1Ensure that the desktop unit is not connected to power.
2Slide the Campus-REX2 into the guide rails in the rear of the
desktop unit.
3Gently press the card into place until it is seated firmly in the mating
connector.
4Secure the card in place using the two captive screws.
5Complete the desktop unit installation using the Campus-RS Desktop
Unit User Manual.
Ensure power is off to the desktop unit before you install the
Campus-REX2. Installing the card with the power on may
cause damage to the desktop unit, the card, or to both.

Installing into a Campus-Star Chassis
The Campus-REX2 must be installed into a Campus-Star chassis first, before
you install the corresponding Campus-RS or Campus-HRS line unit.
1Ensure that a line unit is not installed in the line-unit slot corresponding
to the slot where you will install the Campus-REX2.
2Slide the Campus-REX2 into the guide rails oftheselectedslotat the rear
of the Campus-Star chassis.
The Campus-REX2 is not hot-swappable. Damage may occur
to the Campus-REX2, the line unit, or both if the line unit is
installed before you install the Campus-REX2.

4Secure the card in place using the two captive screws.
5Install a Campus-RS line unit and connect it to an HDSL line using the
Campus-RS Line Unit User Manual. The line unit provides the DSL
connection for the interface card.
CONNECTING THE ETHERNET LINE
The 10 Base-T and100 Base-Tx (10/100Base-T) port on the rear panel of the
Campus-REX2 connects to a LAN through a hub, repeater, or another router.
The port autosenses both the 10/100Base-T port rate and half- or full-duplex
mode of the network device to which it connects and matches the
configuration.
Use a straight-through Category 5 cable to connect the Ethernet port. Set the
MDI/MDI-X switch to the appropriate position, dependent on the device to
which you are connecting.
1Set the Campus-REX2 MDI/MDI-X switch to one of the following:
•MDI-X when connecting to
network equipment such as
an Ethernet NIC in a PC or
any other equipment that has
an MDI port
•MDI when connecting to
network equipment such as a
hub, switch, or router or any other equipment that has an
MDI-X port
Use when connecting
to an MDI port such as
a PC Ethernet NIC

2Plug one end of the Category 5 cable into the 10/100Base-T connector on
the Campus-REX2 faceplate.
3Connect the other end of the Ethernet cable to the local Ethernet
equipment (repeater, PC NIC, or other Ethernet device).
The Campus-REX2 10/100Base-T interface operates in either
half- or full-duplex mode which is determined by autosensing
its network connection. Both the LCD menu and console
menu displays the mode.

POWERING UPAND CHECKING THE CONNECTION
Verify operating status after completing a full installation that includes
installing of the Campus-REX2 into a desktop unit or Campus-Star chassis
and then completing the installation of the desktop unit or the Campus-Star
chassis (including the Line Unit):
1Verify that the power cord is connected to the desktop unit or to the
Campus-Star chassis (if you have an AC power supply) and to an
external power source. Then verify the powerup of and HDSL
connection for that unit as specified in the appropriate user manual.
2If the Campus-REX2 is installed in a desktop unit, press the power button
to On. The button is located on the back of the desktop unit.
3Verify that the Link LED on the Campus-REX2 card is green. This
indicates that the 10/100Base-T connection is operating correctly. If the
Link LED does not light green, check the 10/100Base-T cabling
configuration.
If the link LED does not light green, check that the MDI/MDI-X switch
is set to the appropriate position.

SETTING UPACCESS TO THE CAMPUS UNIT
Configure a Campus system through any of the following:
•a PC connected to the desktop unit Console port
•a PC connected to the Campus-Star line unit Console port
•a telnet session to the Campus-REX2 over the Internet or the CMU in a
Campus-Star chassis
•the LCD menu and buttons on the desktop unit or CMU front panel
•StarGazer or a comparable EMS using SNMP
A Console port or telnet connection provides access to configuration menus
that provide options not available through the LCD menus. Depending on
your immediate configuration requirements, you may not need to set up a PC
immediately. Use the Console port or a telnet session when you:
•configurethe Campus-REX2 as a router (only some bridging and routing
configuration is available using the LCD)
•want to change the HDSL transmission rate and do not want to use the
LCD menus
•will set additional configuration options at this time, such as system or
REX2
•want to view performance statistics for the HDSL and 10/100Base-T
interfaces
If you want to set up a PC at this time, refer to “Setting Up Access to the
Campus Unit” on page 8.
