For the firmware update process, the McDATA management
interface requires administrators to log in to the switch using the
“admin” account and access the advanced configuration console
mode using the admin start command. 4
Brocade Silkworm 3014 Fibre Channel switch firmware. Brocade
Fibre Channel switch firmware can be upgraded using either a
Web-based GUI or a CLI. To update the fabric OS in command-
line mode, administrators should execute the firmwaredownload
command from an FTP server or from a local Network File System
(NFS) directory while in admin mode:
firmwaredownload options host_or_IP,user,
/path/to/the/pfile,passwd
The updated firmware is in the form of Red Hat ® Package
Manager (RPM ™ ) packages with names defined in pfile, a binary
file that contains specific firmware information and the names of
firmware packages to be downloaded.
In dual-domain systems, the firmwaredownload command
downloads the firmware image by default to both control proces-
sors (CPs) in rollover mode, which helps prevent disruption to
application services. This operation depends on support for the
High-Availability (HA) fea-
ture, which can be enabled
through the haenable com-
mand in the switch CLI.
If HA support is not avail-
able, administrators can still
upgrade the CPs one at a
time, using the –s option. 5
Systems supported by the
Brocade firmware have two
partitions of nonvolatile stor-
age areas—a primary and a
secondary partition—to store
two firmware images. The firmwaredownload command loads the
updated image into the secondary partition and swaps the second-
ary partition to be the primary partition. The command then reboots
the CP and activates the updated image. Finally, it performs the
firmwarecommit procedure automatically to copy the updated
image to the other partition (unless the –n option is used).
To update the firmware using the GUI, administrators should
launch the Brocade Web console by entering the IP address of
the switch in the browser address line. They should then log in
as “admin” and navigate to the Firmware tab. On the Firmware
page, administrators should enter the FTP server’s IP address
and the path to the firmware image file, then begin the firmware
update process.
At the switch console, administrators can use the
firmwaredownloadstatus command to monitor the download
process. After the download is finished, administrators can enter
the firmwareshow command to verify that the firmware update
completed successfully.
Dell PowerConnect 5316M Ethernet switch firmware.
Two firmware images can be stored in the flash memory of the
PowerConnect 5316M switch module. The images are called active
and nonactive, depending on which image the switch is currently
running. The switch also supports two protocols to download the
images: network-based TFTP and serial port–based xmodem.
To use the TFTP method, administrators must complete the
following setup procedures before starting the firmware update
process:
1. Set up a TFTP server.
2. Install the updated firmware image on the TFTP server.
3. Log in to the switch, and enter the privileged EXEC mode. 6
After logging in, administrators can execute the following com-
mand in privileged EXEC mode to copy the file named “image” to
the nonactive image file:
console# copy tftp://hostname/path/to/the/
systemimage flash
After the flash update is complete, the switch can be instructed
to boot from either of the two images by executing the following
command in privileged EXEC mode:
console# boot system {image1 | image2}
Administrators should enter the following command to verify
whe ther the switch successfully booted into the updated system
image:
console# show version
Although administrators may never need to upgrade the switch
boot image, they can do so by executing the following command:

To provide consistent
performance throughout the
fabric, administrators should
ensure that all switch modules
are running the same version
of firmware.
