Switch Faceplate Display (Special>Update Flash)
SANbox-8/16 Switch Management
2-74 SANsurfer Switch Management 59010-06 Rev. A User’s Manual
not correct the application will warn you. The application displays infor-
mation about the progress of the Flash update. This information includes:
• File: The name of the Flash update binary file.
• Position: The name of the Flash update binary file.
• Total: The total number of bytes in the file.
• Complete: The percentage of the file sent to the chassis.
3. When the Flash load is complete, the application displays a dialog box that
states that the Flash load is complete and asks whether to Reset Immediately,
No Reset, or Cancel.
Click Reset Immediately to Reset now. Remember, A Reset operation will
disrupt the operation of the Switch.
To delay the Reset operation until traffic is removed from the Switch, click
No Reset or Cancel (Cancel is the same as No Reset). Perform the Reset later
by choosing Special>Reset in any of the Chassis Faceplate windows. Refer to
the Special>Reset paragraphs later in this manual.
If the Flash load fails, refer to the Flash Load Fails paragraphs.
Flash Load Fails
In the event that the Flash load fails, a dialog box asks whether to try again. The
Switch will still remain operable even after a Reset occurs (Assuming, of course,
that the Switch was operating before an attempt to load new Flash code). Trying
multiple times to load new Flash code will not upset operation of the Switch as
long as the switch isn’t reset.
If a Switch Reset occurs, the Switch will try to use the new Flash code and
discovers that it is bad. The Switch will display a Heartbeat error code of three
blinks indicating a Flash Checksum error and resort to the previously utilized flash
code. The Switch is still able to load new Flash code but is not operable with the
new code until the new code is successfully loaded and the Switch is again Reset.
When the Flash load is successful, Reset the Switch to put the new Flash code into
operation.
NOTE:
On a MKII-16 Switch, if the network is very busy, the Flash Load operation
could time-out before it completes. In this case do not perform any Reset
operations. Make sure that the Flash Load was successful before performing
a Reset. Refer to the Flash Load Fails paragraphs below. A busy network will
have no effect on SANbox Switches.
