Upgrading The Boot Code; Upgrading The Flash Code - Foundry Networks Switch and Router Installation And Configuration Manual

Upgrading POS Software from a TFTP Server
The POS modules contain their own flash memory from which they can boot. To upgrade the boot code or flash
code (system software) on a POS module, copy the upgrade onto a TFTP server to which the Layer 3 Switch has
access, then download the code from the TFTP server to the POS modules in the chassis.
By default, the code on all the POS modules in the chassis is upgraded. If you want to upgrade code only a
particular module, you can specify the module's slot number.
To upgrade the POS software, use the following CLI methods.

Upgrading the Boot Code

To upgrade the POS boot code from a TFTP server, enter a command such as the following:
BigIron# copy tftp flash 109.157.22.26 P2B06000.bin boot
This command upgrades the boot code on all POS modules in the chassis.
Syntax: copy tftp flash <ip-addr> <image-file-name> boot

Upgrading the Flash Code

To upgrade the software in the primary flash on all POS modules in a BigIron Chassis device, enter the following
command at the Privileged EXEC level of the CLI:
BigIron# pos copy tftp flash 109.157.22.26 P2R07100 primary
Syntax: pos copy tftp flash <tftp-server-ip-addr> <pos-image-file-name> primary | secondary [<slot>]
The primary and secondary parameters identify either the primary or secondary flash on the module. For each
command, the parameter specifies the destination of the copy operation.
The slot parameter specifies a chassis slot. This parameter is optional. If you specify a slot number, the upgrade
affects only the module in the slot you specify. If you do not specify a slot, the upgrade affects all the POS
modules in the chassis.
• Slots on a 4-slot chassis are numbered 1 – 4, from top to bottom.
• Slots on an 8-slot chassis are numbered 1 – 8, from left to right.
• Slots on a 15-slot chassis are numbered 1 – 15, from left to right.
To upgrade the software on the secondary flash on the POS module in chassis slot 6 only, enter the following
command:
BigIron# pos copy tftp flash 109.157.22.26 P2R05300 secondary 6
To verify that the download is successful, display the contents of the POS flash modules by entering the following
command at any CLI prompt:
BigIron# show flash
The versions of flash code contained in the redundant management module flash and the POS module flash are
listed.
Configuring POS Boot Parameters
The POS module has its own system software and boots after the management module boots. By default, the
POS boots from the software image in its own primary flash. You can configure a POS module to boot from one
of the following sources:
• POS module's primary flash
• POS module's secondary flash
To boot the POS module from a TFTP server, you must use the interactive boot mode, then enter the pos boot
tftp... command after the module comes up.
