Product Description 1-3
Product
Description The Dual DSX-1 Network Interface Card (NIC), also known as the Short
Haul NIC, eliminates the need for a channel service unit (CSU).
Eliminating the transceiver from the connection reduces the power level
on the cable, which provides a more reliable signal over shorter cable
lengths. This NIC supports cable lengths from 0–655 feet.
Product
Compatibility The Dual DSX-1 NIC is compatible with the following Network
Application Cards:
■Dual Channelized T1 (386)
■Dual T1/PRI

2INSTALLATION
This chapter contains Dual DSX-1 Network Interface Card (NIC)
installation information.
Installation Tools To install this NIC in the Total Control chassis, you need a #2 Phillips and
flat-head screwdriver.
Installation
Procedure To install this NIC:
ESD: To reduce the risk of electrostatic discharge (ESD), take proper
grounding precautions before handling the NIC.
Install the NIC with or without power applied to the chassis.
1Configure the NIC via the jumpers.
For proper operation, confirm that the 10-position jumper is at NORMAL.

2-2 CHAPTER 2: INSTALLATION
2Select a slot at the rear of the Total Control chassis for installing the NIC.
Install this NIC in slot(s): 1–17
For managed chassis, slot 17 is reserved for the Network Management
Card (NMC) NIC.
3Use a #2 Phillips screwdriver to remove the safety panel covering this slot.

Installation Procedure 2-3
4Insert the NIC between the slot’s upper and lower card guides.
5Slide the NIC into the chassis, until the front of the NIC is flush with the
chassis.

2-4 CHAPTER 2: INSTALLATION
6Use a flat-head screwdriver to tighten the screws on the front panel.
7Cover any unused chassis slots with safety panels.
8Install the Network Application Card (NAC) corresponding to this NIC.
Refer to the NAC’s Getting Started Guide for more information.

3NETWORK INTERFACE CARD
CABLING
This chapter provides information about the physical interfaces of the
Dual DSX-1 Network Interface Card (NIC), instructions for accessing the
corresponding Network Application Card (NAC) through the user
interface (UI), and options for configuring the software.
Physical Interfaces The Dual DSX-1 NIC has the following physical interfaces:
Confirm that the monitoring equipment to be
connected is in monitoring (non-intrusive) mode.
Passive coupling attenuates the signal from the
monitoring jacks making it difficult for some monitoring equipment to
sense.
Callout Number Interface Description
1RS-232: RJ-45 RS-232 port
■Connect to this port to access the
corresponding NAC’s UI console.
2MON 1: Bantam Jack with two ports
(TX and RX) for monitoringequipment.
This interface monitors Span 1.
3MON 2: Bantam Jack with two ports
(TX and RX) for monitoringequipment.
This interface monitors Span 2.
4Span 1: 8-pin RJ-48C
Span Line 1 Interface
5Span 2: 8-pin RJ-48C
Span Line 2 Interface

3-2 CHAPTER 3: NETWORK INTERFACE CARD CABLING
Accessing the
User Interface To access the UI of the corresponding NAC, connect the following cables
to the NIC’s console port.
Configuring
Software Configure the NIC for the necessary cable length (0–655 feet) through:
■The NIC’s UI port
■3Com Total Control Manager/Simple Network Management Protocol
(SNMP) software
■A generic Management Information Base (MIB) manager software
application
Configuring the User
Interface Port Connect to the UI port. Refer to the section Accessing the User Interface.
Access the UI console through a terminal emulation program.
Callout Number Description
1RJ-45 connector to NIC’s console port
2DB-25 male connector to modem for remote operations
3DB-25 female-to-female null modem adapter to PC or
terminal COM port

Configuring Software 3-3
Difficulties in connecting are usually the result of mis-matched baud rates
between the NAC and the terminal emulator.
The Dual DSX-1 NIC’s configurable parameter is accessed differently
depending if it is installed behind the Channelized T1-386 or the T1/PRI
NAC.
