If your Wide Bank 28 DS3 Controller cards are equipped with FLASH memory, you can download a

new level of firmware to your Wide Bank. Usually, units with a serial number of 01898491000 or higher

have FLASH capability. The firmware can reside on any TFTP server to which you can connect through

the Ethernet, or it can reside on the PC you are using to manage the download. You must know the file

name of the new firmware, and if you are downloading through the Ethernet you must know the IP

address of the TFTP server on which the firmware resides.

Configurations for Downloading Firmware

A Wide Bank can be physically configured either with one Controller card (non-redundant), or with

two Controller cards (redundant). How your Wide Bank is configured will affect the downloading

process, as well as the continuous processing of traffic.

Downloading Firmware to a non-redundant Wide Bank will cause a short interruption of service (up

to 90 seconds) when the system resets after FLASH is re-programmed. Downloading firmware to

a redundant Wide Bank, when successful, will cause no interruption of service.

The effects to the downloading process are explained in the following procedures.

Management Connections for Downloading Firmware

The options for managing the download are:

 Figure 6-3A: A PC, running terminal emulation (HyperTerminal, for example), connected to the

RS-232 port on the Wide Bank. The settings are 9600, 8 bits, no parity, 1 stop bit.

 Figure 6-3B: A VT100 terminal connected to the RS-232 port on the Wide Bank to control a

download over an Ethernet connection, and the Ethernet port on the Wide Bank connected to the

Ethernet. With this connection, the new firmware must reside on a TFTP server connected to the

Ethernet.

 Figure 6-3C: A Telnet session, connected to the Ethernet, and the Ethernet port on the Wide Bank

connected to an IP network. The TFTP server on which the new level of firmware resides must be

reachable through an IP network as well, and you must know the IP addresses for both the Wide

Bank and the server.
