Upgrade Switches Running Firmware v2.x.x.x to v5.1.9.3 Firmware
The upgrade procedure given below upgrades an individual switch or a stack of switches running firmware version
2.x.x.x. This procedure can be used to update modular switches via the CMC as well. During this process, the switch
may autonomously reboot itself such that it appears the switch rebooted twice. This is a normal operation of the
upgrade procedure. Do not interrupt switch operation during the upgrade process as this may result in
corruption of flash memory. Do not power off a switch undergoing the upgrade process unless specifically
directed to do so by the instructions.
To upgrade a switch running a 2.x.x.x version of firmware to the 5.1.9.3 version of firmware, use the procedure
below. An annotated upgrade example is shown following this section.
1. Back up your configuration.
2. If using telnet or ssh to perform the upgrade procedure and if the current configuration does not contain a
non-default enable authentication method or enable password, configure an enable password and save the
configuration. Example steps to configure an enable password are shown below:
console# configure
console(config)# enable password <XXXXXX>
console(config)# exit
console# copy running-config startup-config
NOTE: It is required that either a non-default privileged exec (enable)
access method or an enable password be saved in the startup config in
order to access privileged exec (enable) mode after the firmware upgrade.
The 5.1.9.3 firmware emulates industry standard behavior for privileged
exec mode authentication over SSH and telnet. In 5.1.9.3, the default
authentication list for telnet and SSH is enableNetList, which requires an
enable password. If the startup configuration being upgraded does not
NOTE: A TFTP server must be on the network and the switch software
must be accessible to the TFTP server before attempting to download
the switch software by TFTP.
