Product Description 1-3
Product
Description
The Token Ring NIC provides a Token Ring interface between a particular
NAC in the 3Com Total Control chassis and your network.
This NIC features one IEEE 802.5 compliant Token Ring interface capable
of data transfer rates of 4 or 16 Mbps. Type 1 (STP) and Type 3 (UTP)
physical ports are available for this interface. In addition, this NIC also
features a RS–232 user interface console port capable of data transfer
rates up to 57.6 Kbps.
Product
Compatibility
The Token Ring NIC is compatible with the NETServer, NetServer PRI and
the 486 Network Management Card (NMC) NAC.

2INSTALLATION
This chapter contains the Token Ring 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 DIP switches.

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.
DIP Switch Number Function
1■OFF: Unshielded Twisted Pair (UTP) Token Ring cable
used
■ON: Shielded Twisted Pair (STP) Token Ring cable used
2■Off: 4 Mbps Token Ring speed connection
■ON: 16 Mbps Token Ring speed connection
3■Off: Token Ring NIC installed behind an NMC NAC
(slot 17 only)
■ON: Token Ring NIC installed behind any other NAC
(Slot 1–16)
4■OFF: Reserved

Installation Procedure 2-3
3Use a #2 Phillips screwdriver to remove the safety panel covering this slot.
4Insert the NIC between the slot’s upper and lower card guides.

2-4 CHAPTER 2: INSTALLATION
5Slide the NIC into the chassis, until the front of the NIC is flush with the
chassis.
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
Token Ring Network Interface Card (NIC) and instructions for accessing
the corresponding Network Application Card (NAC) through the user
interface (UI).
Physical Interfaces The Token Ring NIC has the following physical interfaces:
Callout Number Interface Description
1CH1: RJ-45 RS–232 DTE Port
Used to access the corresponding NAC’s UI
console. This port’s speed is determined by
DIP switch setting on the NAC.
2CH2: RJ-45 RS–232 DTE Port
Used as a dedicated SLIP port when behind
the Network Management Card (NMC). It
is reserved when behind any other NAC.
3STP: DB-9 IBM Type 1 Token Ring port.
4UTP: RJ-45 IBM Type 3 Token Ring port.
