When downgrading to a release prior to 07.00.00-84, 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 necessar y

to allow the configuration to comply with previous releases’ configuration database.

Firmware 07.00.00-84 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 H P web site and

downloading firmware to the switch or director using HA FM.

• The switch or director Element M anager online h elp 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 07.00.00-84 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 07.00.00-84. If EWS is used for upgrades and downgrades, and

this rule is not followed, errors occur and there may be a disruption to at tached devices.

Preferred Paths dialog b ox.
