Downloading Firmware to a Service Module

This section describes how to download firmware for a service module from a workstation. The
descriptions apply whether you are upgrading the existing firmware or downloading because no
runtime firmware resides on the hard drive.
Service modules do not retain runtime firmware. The hard drive on the PXM may come with default
firmware for the service modules, but the details of the customer order actually determine whether
firmware is on the disk. If default firmware exists on the hard drive, the PXM downloads it upon
power-up or when you reset the card, otherwise you can download firmware from the workstation
according to the instructions that follow.
Note that if you download firmware from a workstation to the hard drive, the PXM does not
automatically load the firmware to the card. You must reset the card (resetcd on the CLI) to
download firmware from disk to the card. With the single execution of a command, you can load
either generic firmware for all cards of a certain type or firmware destined to a specific slot.

Step 3
After you enter a user-name and privilege level, the system prompts for a password. The
password is a string of 5–15 characters. If you press Return without entering a password,
the system assigns the default password "newuser."
Optionally change your password or another user's password by executing:
cnfpasswd [username]
username is the name of another user whose password you are changing. That user must
have a privilege level that is lower than your privilege. To change your own password,
enter cnfpasswd with no username.
To specify the switch as a feeder, execute the cnfswfunc command:
cnfswfunc <-ndtype>
and follow -ndtype with "fdr."
Configure as needed an external clock by executing cnfextclk.
Start the tftp application:
$tftp <IP address>
then
>bin
To download generic firmware for a type of service module to the PXM hard drive:
>put cardtype.fw POPEYE@SM_1_0.FW
where cardtype is the firmware for a type of card; the shelf number always is 1; and the 0
represents the slot number for the purpose of generic download. An example of
cardtype.fw is "frsm8t1e1_10.0.11.fw." Note the space between ".fw" and "POPEYE."
To load slot-specific firmware at a particular card:
>put cardtype.fw POPEYE@SM_1_slot.FW
where cardtype is the firmware, and slot is the number of the card slot. Note the space
between ".fw" and "POPEYE." Repeat this step for each slot as needed.
