Introduction

The DECrepeater 90TS (also referred to in this manual as the module) is an 8-port
10BaseT Ethernet* repeater. The module provides eight shielded10BaseT ports
using 8-pin modular jack (MJ-8) connectors. The module also provides a ThinWire
interface and a back cover AUI connector.

To give your workgroup LAN media flexibility and connectivity, the DECrepeater
90TS can be configured into a DEChub 900 MultiSwitch (also referred to in this
manual as the DEChub 900), a DEChub 90, or as a standalone unit. One or more
modules (up to 8) can be installed into the DEChub 900 or the DEChub 90.

When installing the module into a DEChub 900 or in a DEChub 90, the module’s
hot-swap capability allows you to install or remove the module without turning off
power.

The module’s eight 10BaseT ports (MJ-8 connectors) are located on the front panel,
and support 100-ohm unshielded twisted pair (UTP) and 100-ohm shielded
twisted-pair (STP) cables.

The module’s ThinWire interface attaches to the ThinWire segment in the DEChub
900 or the DEChub 90. A side panel ThinWire BNC is also provided for standalone
use. The AUI connector can only be used in the standalone configuration. The
ThinWire and AUI interface connect internally to the same port, so one or the other
(but not both) can be active at any given time by software configuration.

The module’s front panel contains light-emitting diodes (LEDs) that indicate the
status of the 10BaseT ports, the ThinWire network port, and the AUI network port.
Other LEDs on the front panel indicate the status of the module, power, and network
activity .

The module includes a serial port on the front panel that can be used as an
installation setup port when the module is installed into a DEChub 90 or installed as a
standalone unit. Using the setup menu, you can enable the module’s front panel
serial port for Out-of-Band Management (OBM).

NOTE: When the module is installed in a DEChub 900, you

must use the Hub Manager setup port on the DEChub
900 instead of the module’s setup port.

In this manual, the term Ethernet is Digital’s term for its product compatibility with the ISO

*

8802-3/ANSI/IEEE 802.3 standards and the Ethernet standards for Carrier Sense Multiple
Access with Collision Detection (CSMA/CD) local area networks (LANs).

tional AUI connector on the back cover, available as an external network con­nection (when the module is installed as a standalone unit).

• Backplane access to another Ethernet LAN through a single flexible channel in a

DEChub 900.

• Automatic module self-test at powerup.

• Port-level packet address security.

• In-band Simple Network Management Protocol (SNMP) management.

• OBM using SNMP over Serial Line Internet Protocol (SLIP) provides an addi-

tional path to the normal in-band management as follows:

– Through the OBM connector on the DEChub 900 Hub Manager.
– Through the front-panel serial port on the module when the module is

installed in a DEChub 90 or as a standalone unit.

• Built-in SNMP agent supports the following management information bases

(MIBs):

– Ethernet-like Interface Type MIB (RFC 1398)
– Repeater MIB (RFC 1516)

– Digital Extended Repeater MIB
– DEChub 900 Public Common MIB

– MIB II (RFC 1213)

• Manageability using any generic SNMP management application that supports

the MIBs listed above.

• Upgradeable device firmware (in nonvolatile Flash memory) using Trivial File

Transfer Protocol (TFTP) with Digital’s Network Device Upgrade (DECndu) Plus
utility or through the setup port with any TFTP server.

Installing the Module as a Standalone Unit

You can use the DECrepeater 90TS as a standalone unit by placing it on a table,
mounting it onto a wall, or installing it into a standard 19-inch rack using a shelf
assembly (Digital Part Number: H9544–MS).

In standalone mode, you can operate your module with or without a back cover. If the
back cover is installed, either the ThinWire port or the AUI port can be used to
connect the module to the network. If the back cover is removed, only the ThinWire
port is available.

The module’s factory default settings automatically select either the ThinWire port or
the AUI port, depending on which one is connected. If you connect both the ThinWire
port and the AUI port to the network(s), the module selects the AUI port by default.
Using HUBwatch, you can change the module’s port selection to use either the
ThinWire port or the AUI port.

NOTE: In the standalone mode, connections are normally made

to either the ThinWire port or the AUI port, not both.
Only one of the two ports can be active at a time. It is not
necessary to place a terminator or loopback connector
on the nonactive port.

Connecting the UTP/STP Cables

The DECrepeater 90TS module uses crossover 10BaseT (8-pin MJ) port connectors.
The appropriate UTP/STP cable type, crossover or straight-through, is required to
ensure that the module’s transmit/receive signals connect correctly to the
transmitter/receiver of the connected device.

Before connecting the cables to the module, note the following:

• If the device you are connecting to the module uses straight-through connectors,

use straight-through cables.

• If the device you are connecting to the module uses crossover connectors, use

crossover cables.

• The sum of the number of crossovers must always equal an odd number.

NOTE: Digital’s straight-through cables are marked (=);

crossover connectors (and cables) are marked (X).

If you need help determining the appropriate cable type to use, refer to the section titled
Connector Pin Assignments, on page 51.

1 Connect the UTP/STP cables:

Setup Port Description

The setup port on the DEChub 900 MultiSwitch or on the module’s front-panel serial
port (when the module is operating as a standalone unit or in a DEChub 90) allows
you to access and set DECrepeater 90TS parameters. This section describes how to
access the module from either port and set those parameters.

NOTE: The setup port screen displays illustrated in this manual

may vary slightly from the actual screen displays on your
setup port device.

The signals from the DEChub 900 Hub Manager setup port and from the
DECrepeater 90TS front-panel serial port conform to the EIA-232D signaling
standard at 9600 baud. To the user , the port appears as a data terminal equipment
(DTE) device.

NOTE: Devices that use the EIA-423 signaling standard are

compatible with the DEChub 900 Hub Manager setup
port and the DECrepeater 90TS front-panel serial port.

Setup Port Device Cabling

The front-panel serial port on the module or the Hub Manager setup port on the
DEChub 900 can be connected to a setup port device (a terminal or personal
computer), using the following cables and adapters (not included in the shipping kit).
