10. Click the OK button to close the Software Upgrade window. The unit will disconnect
the Web session and be unavailable for both Telnet and Web access for 1—2
minutes while it overwrites the old software.
CAUTION: Do not power down or reset the Switch or attempt to stop the
upgrade once it has begun. Interrupting the upgrade will cause the Switch to
become unusable.
11. The Switch will reset when the upgrade is complete, and the Power/Self test LED
will change from flashing ON/OFF Green to solid Green.
Once the LED shows as solid Green the upgrade has been completed and the unit
is again ready for Telnet and Web access.
If you are unable to access the Switch through the Web Interface or through the
Command Line Interface, then it is possible that you can no longer manage your Switch
due to a failure during the software upgrade. Refer to the
Solving Management Software
Upgrade Problems section of the Management Interface Reference Guide for further
assistance.
