Application Card (NAC).

2INSTALLATION
This chapter contains Dual E3 Asynchronous Transfer Mode (ATM)
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.
1Select a slot at the rear of the Total Control chassis for installing the NIC.
Install this NIC in slots: 1–17
CAUTION: The Dual E3 ATM NIC must be installed behind a HiPer Access
Router Card (ARC) Network Application Card (NAC).

2-2 CHAPTER 2: INSTALLATION
For managed chassis, slot 17 is reserved for a NIC corresponding to the
Network Management Card (NMC).
2Use a #2 Phillips screwdriver to remove the safety panel covering
this slot.

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

2-4 CHAPTER 2: INSTALLATION
5Use a flat-head screwdriver to tighten the screws on the front panel.
6Cover any unused chassis slots with safety panels.
7Install the HiPer ARC NAC. Refer to the HiPer ARC NAC Getting Started
Guide for more information.

3NETWORK INTERFACE CARD
CABLING
This chapter provides information about the physical interfaces of the
Dual E3 Asynchronous Transfer Mode (ATM) Network Interface Card
(NIC), instructions for accessing the corresponding Network Application
Card (NAC) through the command line interface (CLI), and options for
cabling the E3 port.
Physical Interfaces The Dual E3 ATM NIC has the following physical interfaces:
Callout Interface Description
1Console:
RJ-45 RS-232-C port configured as DTE.
■Connect to this port to access the
HiPer ARC NAC’s CLI. This port is
configured for 8 data bits, 1 stop bit,
no parity. This port’s baud rate is
selectable via DIP switch settings on
the HiPer ARC NAC.
2Span A TX:
BNC E3 transmit port for Span A.
3Span A RX:
BNC E3 receive port for Span A.
4Span B TX:
BNC E3 transmit port for Span B.
5Span B RX:
BNC E3 receive port for Span B.
610/100 Mbps Ethernet:
RJ-45 Ethernet port.
■This port auto-senses Ethernet
10Base-T or 100Base-TX networks.

Accessing the
Command Line
Interface
To access the CLI of the corresponding NAC, connect the following cables
to the NIC’s console port.
E3 Port Cabling
Options Cable the ATM NIC’s E3 span ports for an independent connection
between a single chassis and the ATM switch, or for multiple cascaded
chassis with a single connection to the switch.
The Span B port must be used for cascading multiple chassis. It cannot be
used as an independent connection to an ATM switch.
Cabling a Single ATM
Network Interface
Card
To cable a single chassis to an ATM switch, connect the ATM switch to the
ATM NIC’s Span A port. Refer to the Dual E3 ATM NIC Product Reference
for configuration information.
