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 d irector 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 inter face.

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 ﬁ rst 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 attached devices.

Downgrading to release 6.0 with the Preferred Path feature con ﬁgured could cause loss

of this function. HP recommends that Preferred Path be disabled before downgrading.

To do this, d eselect the check box for Enab l e Preferred Path in the Conﬁgure Preferred

Paths dialog box.

NOTE:

The D irector 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.

If a Director 2/140 in a multiswitch fabric is downgraded earlier than 06.02.00, ISLs

could become segmented if there are any other switches in the fabric operating with a

ﬁrmware version earlier than 06.01.00. To prevent this situation, downgrade all Director

2/140s in the fabric to 06.01.00 b efore downgrading any products in the fabric to

05.xx.xx. This problem only exists with Director 2/140s in the fabric. HAFM displays a

warning message if a downgrade from 06.02.00 is attempted, but you c an continue

with the downgrade if desired.

NOTE:

The warning message is displayed when downgrading any model from 06.02.00, but

only applies to downgrade op erations for the Director 2/140.

Downgrades directly to 05.03.01 from 06.xx.xx is not concurrent when the

second-generation Edge Switch 2 /24 is conﬁgured in Open Fabric operating

ode. In other words, downgrades in Open Fabric modecannotbedonewiththe

econd-generation Edge Switch 2/24 online without d isrupting port operations. Since
