DECswitch 900EE Installation
Introduction
The DECswitch 900EE (also referred to in this manual as the module) provides the
interconnection between six 10 Mb/s Ethernet1 LANs.
As a self-learning IEEE 802.1d Media Access Control (MAC) bridge, the module
performs standard functions such as filtering and forwarding.
The DECswitch 900EE module is protocol-independent. As such, it accommodates
multiple protocols such as DECnet, LAT, TCP/IP, or any other protocol running on
Ethernet LANs. The module operates transparently for plug-and-play network
operations and also includes flexible filtering options for destination and source
addresses and protocols.
These features can be accessed through Simple Network Management Protocol
(SNMP) management software, allowing network managers to determine which
users or groups of users can gain access to the networks. As with other bridge
products from Digital, access to network management can be restricted by password
protection.
The DECswitch 900EE standards-compliant technology (IEEE 802.1d, 802.2, and
802.3) ensures operability in multivendor networks.
The module can be configured into the DEChub 900 MultiSwitch (also referred to in
this manual as the DEChub 900) and can also be configured as a standalone unit into
a DEChub ONE2 docking station.
Features
Your DECswitch 900EE module includes the following features:
• High-speed local traffic filtering and forwarding.
• Supports up to 8000 network addresses.
• Option to turn off automatic learning and manually load the address database.
1
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).
2
Throughout this manual, the term DEChub ONE refers to the DEChub ONE or the
DEChub ONE-MX docking station unless otherwise specified.

Introduction (Cont.)
• Configurable rate limiting of multicast packets to limit the spread of multicast and
broadcast storms.
• Flexible filtering capabilities (source address, destination address, and proto-
col) for greater network control, increased security and bandwidth utilization,
and reduced propagation of network problems.
• Spanning tree loop detection protocol:
– IEEE 802.1d (default)
– Digital LB100 mode
• Built-in SNMP agent supports the following:
– SNMP management (RFC-1157)
– MIB II (RFC-1213)
– Bridge MIB (RFC-1493)
– Ethernet MIB (RFC-1398)
– Digital ELAN MIB Extensions
• Manageability using any generic SNMP management application that supports
the MIBs listed above.
• User-friendly advanced Graphical User Interface (GUI) manageability with
Digital’s HUBwatch Network Management Station (NMS) application.
• Six 802.3/Ethernet LAN ports that are individually switchable to a DEChub 900
backplane LAN through HUBwatch management. When the module is installed
into a DEChub ONE docking station, one of the 10BaseT ports can be switched
to the DEChub ONE AUI connector.
• Out-of-band management (OBM) using SNMP over Serial Line Internet Proto-
col (SLIP) through the OBM connector as an alternative to normal in-band management.
• Setup port for the initial setup of the module using a setup port device (a terminal
or personal computer).
• 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
The DECswitch 900EE hot-swap feature allows you to install the module into the
DEChub 900 or DEChub ONE docking station without turning off power . Seating the
module initiates the module powerup sequence if enough power is available.
1 Compare your module’s power
requirements with the values
shown in the Hub Manager status
display (see example).
NOTE: The 12V power in the DEChub 900 is derived from the
15V power source. Although it is listed separately in the
product specifications, the 12V requirements are
included in the 15V power total.
2 Seat the module into the
DEChub 900.
a. Place the module’s mounting
tab into a mounting slot on the
DEChub 900.
b. Pivot the module on the mount-
ing tab and align the connectors.
c. Firmly push the module onto the
backplane connectors until the
release lever clicks.
d. Press down on the release lever
to ensure that it is locked.

4 Connect the port cables.
Depending on your network configuration requirements, connect the appropriate
AUI cables and UTP/STP cables. After all cables are connected, go to the section
titled Configuring the Module.
See your network manager if you are not sure which cables to connect.
NOTE: All cables should be installed, tested, and tagged at the
site, prior to this installation.
• To connect AUI cables, go to step 5.
• To connect UTP/STP cables, go to step 6.

5 Connect the AUI cables.
a. Push the module’s AUI con-
nector slide latch to the unlocked position.
b. Insert the AUI cable plug into
the AUI connector.
c. Push the module’s AUI con-
nector slide latch to the
locked position.
NOTE: To disconnect the cables, push the connector slide latch
to the unlocked position, then disconnect the cable.
6 Connect the UTP/STP cables.
The DECswitch 900EE module uses straight-through 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 crossover cables.
• If the device you are connecting to the module uses crossover connectors, use
straight-through cables.
• The sum 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.

Configuring the Module
Setup Port Description
The setup port (on the DEChub 900 MultiSwitch or the DEChub ONE) allows you to
access and set DECswitch 900EE parameters. This section describes how to access
the module from either the DEChub 900 or the DEChub ONE.
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 DEChub
ONE setup 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.
Setup Port Device Cabling
The setup port on the DEChub 900 MultiSwitch or the DEChub ONE can be
connected to a setup port device (a terminal or personal computer), using the
following cables and adapters.
