Installing firmware

Installing firmware involves loading, unpacking, and activating the firmware image on the switch.
QuickTools does this in one operation. To provide consistent performance throughout the fabric, ensure
that all switches are running the same version of firmware.
A Nondisruptive Code Load and Activation (NDCLA) of firmware can be achieved on an operating switch
without disrupting data traffic or having to re-initialize attached devices. As part of an NDCLA operation,
a switch Hot Reset is executed. During a Hot Reset operation, fabric services become unavailable for a
short period (30—75 seconds depending on switch model). To ensure that an NDCLA operation is
successful, verify that all administrative changes to the fabric (if any) are complete. If you are installing
firmware on more than one switch in the fabric, wait until the activation is complete on the first switch
before installing firmware on a second switch. If you attempt to activate firmware on a second switch
before activation is complete on the first, you will receive a message advising you to wait and perform a
hot reset later on the second switch to complete the installation.
CAUTION: Changes to the fabric may disrupt the NDCLA process.
Common administrative operations that change the fabric include:
• Zoning modifications
• Adding, moving or removing devices attached to the switch fabric. This includes powering up or
powering down attached devices.
• Adding, moving or removing ISLs or other connections.
After an NDCLA operation is complete, management connections must be re-initiated:
• QuickTools sessions reconnect automatically.
• Telnet sessions must be restarted manually.
Future switch firmware releases will support non-disruptive upgrades unless specifically indicated in its
associated release notes.
An NDCLA operation to earlier switch firmware releases is not supported.
The Load Firmware dialog box
the Load Firmware dialog box for an individual switch, select Switch > Load Firmware. When the Load
Firmware dialog box is opened, the path displayed in the Firmware Image Folder field is automatically
searched for firmware image files that can be installed. The default path to search for firmware image files
is the user's working directory.
To change the search path:
1. Click Browse and select a new path.
