Using the Product Manager, execute a CTP swap:

From the Product/Element Manager Hardware view, verify that an amber LED indicator is

not displayed for either CTP card.

Right-click the CTP card you believe to be active, and then select FRU Properties. Verify that

it is the active CTP card.

Right-click the active CTP card and select Switchover.

The Director loses its Ethernet connection for a short time during the switchover process.

When switchover occurs, the green LED illuminates on the backup CTP card to indicate that

it is now the active card.

Upgrade the ﬁrmware to 05.02.00-13 on each Director by selecting Send in the Firmware Library

dialog box.

Upgrading ﬁrmware on an Edge Switch from 04.xx.xx to 05.xx.xx

An issue has been identiﬁed in release 04.xx.xx if the contents of the NVRAM on the CTP are corrupted.

Once the conﬁguration has been loaded, this corruption is not detected until an IPL/IML, power cycle, or

ﬁrmware code load. If the NVRAM on the CTP has corrupted contents, the ﬁrmware load can cause the

conﬁguration to reset to factory defaults, which can cause a system outage.

Edge switch products already running 05.01.00 or later continually validate the NVRAM conﬁguration,

so risk of an outage is extremely low. For Edge Switch products running an earlier version of ﬁrmware,

the risk of an outage increases due to the NVRAM issue. If an outage compromises system integrity, HP

recommends that the Edge Switch ﬁrmware upgrade be a scheduled maintenance action that anticipates

the failure of switch connectivity. This issue has been resolved with ﬁrmware 05.02.00-13 and later.

To safely upgrade ﬁrmware on an Edge Switch:

Upgrade HAFM software on the HAFM Server/Appliance to 07.01.00 (minimum).

Download ﬁrmware 05.02.00-13 by selecting Firmware Library from the Product Manager

Maintenance menu.

Back up the Edge Switch conﬁguration by selecting Backup & Restore Conﬁguration from the Product

Manager Maintenance menu.

Upgrade the ﬁrmware to 05.02.00-13 on each Edge Switch by selecting Send in the Firmware

Library dialog box.

Considerations for downgrading the ﬁrmware version

Directors or Edge Switches are not required to be ofﬂine before performing a ﬁrmware downgrade

operation. Limitations to downgrades are clearly identiﬁed if there are any limitations to performing the

operation.

Before downgrading ﬁrmware, HP recommends that you back up the Director or Edge Switch

conﬁguration. Refer to the Director or Edge Switch Element Manager user guide for more information.

EWS (HAFM Basic) also provides an option to print or save product conﬁguration to a ﬁle. See the HAFM

or EFCM Basic user guide for more information.

Consider the following when downgrading ﬁrmware:

•

Before downgrading to a release prior to 07.00.00, there can be only one user assigned as

Administrator and one user assigned as Operator for HAFM Basic and command line interface

(CLI). If additional users were created, you must delete them before downgrading. Firmware

07.xx.xx does not allow the last user with Administrator rights in HAFM Basic or CLI to be deleted.

If no Operator user exists, ﬁrmware 07.xx.xx automatically creates one for each interface during

the downgrade. If more than one Administrator and/or one Operator exists for HAFM Basic

and/or CLI, when attempting to downgrade, you are prompted to delete one of them ﬁrst.
