The DECswitch S00EF (also referred io in this manual as the module) provides the

interconnection between six 10 Mb/s Ethernet? LANs and a high-speed 100 Mb/s
Fiber Distributed Data interface (FDDI) network backbone.

As a self-learning IEEE 802.1d Media Access Control (MAC) switch, the modu'e

performs standard functions such as fittering and forwarding. In addition, the module
performs high-speed, transparent translation of network data packets between the
FDDI and Ethernet networks.

The DECswitch S00EF module is protocol-independent. As such, it accommodates
multiple protocols such as DECnet, Local Area Transport (LAT), Transmission
Control Protocol/internet Protocol (TCP/IP), or any other protocol running on FDDI
and Ethernet LANs. The module operates transparently tor plug-and-play network
operations and also includes flexible filtering options for destination and source
addresses and protocols.

Filters can be accessed through Simple Network Management Protocol (SNMP)
management software, allowing network managers to determine which users or

Jroups of users can gain access to the networks. As with other switch products from
Digital, access to network management can be restricted by password prot. ction.
The DECswitch 900EF standards-compliant technology (IEEE 802.1d, 802.1h,
802.1i, 802.2, 802.3, and ANSI FDDI) ensures interoperability in multivendor
networks.

The module can be configured into the DEChub 900 MuttiSwitch (also referred to in

this manual as the DEChub 900) or as a standalone unit into a DEChub ONE3
docking station (see the DEChub ONE-MX Instaflation manual or the DEChub ONE
Installation manual).

1 The DECbridge 900MX has the same functions and features as the DECswitch 900EF.

2 In this manual, the term Ethernet is Digital’s term for its product cor patibility with the
SO 8802-3/ANSVIEEE 802.3 standards and the Ethernet standards for Carrier Sense

Multiple Access with Collision Detection (CSMA/CD) local area netrvorks (LANs).

3 Throughout this manual, the term DEChub ONE refers to the DEC,hub ONE~-MX or the
DEChub ONE docking station unless otherwise specified.

[6] Downiine Upgrade
This option allows you to upgrade the module firmware (in nonvolatile Flash
memory). It prompts you to enter the loadimage file name and the IP address of your
TFTP (Trivial File Transfer Protocol) load host.

Betore initiating this option, be sure that the module that you are upgrading has been

configured with an IP address (refer
to option [4]). If the module is not configured with
an P address, you can still upgrade the module by selecting the Downline
Upgrade option from the DEChub 900 MultiSwitch INSTALLATION MENU.
Refer to the DEChub 900 MultiSwitch Owner’s Manual for more information.

NOTE:

The module's IP address is retained at the completion of
the downline upgrade process.

Examples of an image file name and an IP address are as follow ::
defbal50.bin and 16.20.54.156

The format of the image file name is specified according to the convertions used by
your TFTP load host.

CAUTION A It power is interrupted during Stage 3 of the DLU process,

the firmware image can become corrupted. Do not turn off
power to the unit or perform any action that can cause the

unit to lose power during Stage 3 of the DLU process.
NOTE:

|if the

module

loses

power,

contact your service

representative.

The Downline Upgrade (DLU) Process:
The DLU process consists of four stages.

Stage 1 — Transferring Firmware Image

Stage 2 — Veritying Firmware Image

Stage 3 — Writing New Firmware Image into Flash memory

Stage 4 — Module Reset and Self-Test

Table 1 describes what happens during each stage of the DLU Process.

DECswitch 900EF Instaliation

[‘(‘5] Downline Upgrade (Cont.)
Table 1

DLU Process Description

Stage

What Happens

The new firmware image from the TFTP load host is transported across the network and placed into a temporary storage
buffer In the module.

Indications that this stage is in progress include:
¢ Module status — functional, and manageable.
+ Module can respond to management requests.

+ LED display — normal operational.
+ HUB Manager display —

This stage normally completes in 1 minute, however, because of
variances in network configurations (load path, bit rate, and traffic
levels), this stage of the DLU process can take up to 10 minutes to
complete.

The module verifies that the firmware image Is correct after
Stage 1 is complete.

Indications that this stage is in progress include:
» Module status — functional.

+ Module can respond to management requests.
» LED display — normal operational.

+ HUB Manager display —
This stage normally completes in 1 second.

The new firmware image is transferred from the module’s temporary storage buffer to the nonvolatile Flash memory, over-

writing the old firmware image.

If the module loses power during Stage 3 of the process, contact your Digi-

1al representative.

CAUTION A

If power is interrupted during Stage 3 of the DLU process, the

firmware image can become corrupted. Do not tum off power to

the unit or perform any action that can cause the unit to lose power during Stage 3 of the DLU process.

This option allows you to configure the IPX switch. The Novell Internetworking
Protocol eXchange (IPX) interconnects LANS to allow communication between client
and server.

When the IPX switch is enabled the DECswitch 900EF translates raw 802.3 frames
to SNAP encapsulated FDDIframes with a protocol type 81-37. When disabled, IPX
frames are translated without SNAP encapsulation. The current state of the IPX
switch can be viewed by selecting option (3] Show Current Settingsinthe

[2] Run Extended Diagnostics

This option aliows you to run certain extended diagnostics tests if you suspect that
the module is faulty. The extended diagnostics test is the Ethernet backplane
loopback test. All other tests run as part of the normal powerup self-test.

CAUTION A This action deletes all configured settings and replaces

them with factory default values. All configuration

settings will be lost.

NOTE:

This option is meant to facilitate fault diagnosis under
certain conditions. There is normally no need to select
this option.
The extended diagnostics tests will disrupt operation on

the DEChub backplane and on network segments

connectedto the switch ports. in addition, the switch will
be reset to factory defauits at the end of the tests. As a
result, all configuration parameters stored in nonvolatile
Flash memory are erased. Please be sure to observe

the following precautions before proceeding further with
the extended diagnostics test:
1. Record any configuration parameters, such as the
module’s IP address and address filters that you

would like to restore after the test.

Disconncect all modules other than this switch from
backplane channels. Do this by physically

removing the modules from the hub or using the
HUBwatch LAN Interconnect view.
