Before downgrading below 07.01.02-4, there can only be one user assigned access rights as Administrator and one user assigned as Operator for Embedded Web Server and CLI. If additional users were created, you have to delete them before downgrading. Firmware 07.01.02-4 does not allow the last user with Administrator rights in Embedded Web Server or CLI to be deleted. If no Operator user exists, firmware 07.01.02-4 automatically creates one for each interface during the downgrade. If more than one Administrator and/or one Operator exists for Embedded Web Server and/or CLI, when attempting to downgrade you are prompted to delete one of them first.

When downgrading to a release prior to 07.01.02-4, any modifications to the port RX BB_Credit settings using the new enhanced port configuration capability must be changed back to a configuration supported by older firmware. This is necessary to allow the configuration to comply with previous releases’ configuration database. Firmware 07.01.02-4 services verify compatibility and prevent downloads until the configuration conflict is resolved.

For procedures to download firmware to the switch or director using the HAFM Element Manager interface or EWS interface, refer to the following:

•The switch or director Installation and Service Manual. This publication provides complete procedures for obtaining firmware from the HP web site and downloading firmware to the switch or director using HAFM.

•The switch or director Element Manager online help and User Manual. These includes instructions for downloading firmware to the switch or director using the HAFM interface.

•EWS User Manual. This provides procedures for downloading firmware to the switch or director.

•EWS online help. This provides procedures for downloading firmware to the switch or director.

Downgrading directly to a release before 06.00.00 from 07.01.02-4 is not allowed. To downgrade to a release before 06.00.00, you must first downgrade to 06.YY.ZZ.

Upgrades and downgrades are supported only from one major release to the next, such as from 06.xx.xx to 07.01.02-4. If EWS is used for upgrades and downgrades, and this rule is not followed, errors occur and there may be a disruption to attached devices.

Downgrading to release 6.0 with the Preferred Path feature configured could cause loss of this function. HP recommends that Preferred Path be disabled before downgrading. To do this, deselect the check box for Enable Preferred Path in the Configure Preferred Paths dialog box.

NOTE:

The Director 2/140 and the Edge Switch 2/24 cannot be downgraded earlier than 04.01.00, and the Edge Switch 2/12 cannot be downgraded earlier than 05.05.00.
