1 - 8 ONline Ethernet Bridge Module Installation and Operation Guide
Downloadable Firmware
As firmware upgrades become available from 3Com, you can download
this new firmware to your Bridge Module using an IBM-compatible PC
connected to the module's RS-232 serial port. Downloadable firmware
ensures that you have access to new features as soon as possible - saving
the cost, time, and inconvenience of installing new PROM chips. This
feature is explained in detail in Chapter 6, Firmware Download Instructions.
A 3Com Firmware Distribution Kit (Part number 5000-FDK) is necessary for
downloading the firmware to your Bridge Module. This kit contains the
appropriate RS-232 cable and software for performing future firmware
upgrades. The kit is ordered as a single copy per site, supporting multiple
Bridge Modules. The upgrades themselves are contained in another kit, the
Ethernet Bridge Update Distribution Kit (Part number 5102B-UDK-x.x).
The Ethernet Bridge Update Distribution Kit is available in two versions -
limited and unlimited. The limited version (5102B-UDKL-x.x) allows you to
upgrade only one Bridge Module. The unlimited version (5102B-UDKU-x.x)
enables you to upgrade an unlimited number of Bridge Modules.
Network Management Capabilities
You access the Bridge Module management functions through an
out-of-band connection via the serial RS-232 port on the front panel. You
can also access the module through an inband connection from an existing
Bridge Module, Midnight Bridge, or network management module. To
manage all other Bridge Modules and manageable devices in the extended
LAN via inband management, you must first log out of the current session
and then log in to another device. Refer to the REMOTE_LOGIN command
in Chapter 4 for details on accessing remote devices.
Connection through the RS-232 port means you can manage your Ethernet
Bridge Modules locally, from remote locations using modems and dial-up
telephone lines, and through LAN-based terminal servers.
