To configure the PCICC, PCICA, PCIXCC, CEX2C, CEX2A, CEX3C, or CEX3A cards online and offline, you must use the support element (SE) panel.

Before configuring a card offline, it is strongly recommended that you deactivate the card first from the ICSF Coprocessor Management panel. You need to 'deactivate' the card in ALL partitions that are using that card. This allow jobs to complete before the card is varied offline. You use the Configure On/Off service on the Support Element panel to take the card offline (standby).

After you configure the card offline from the SE panel, hit enter on the coprocessor management panel to verify that the card is offline. This configuring is done to remove and replace cards or to load new card code for the PCIXCC, CEX2C, CEX3C, and PCICC cards.

To bring a card back online, use the SE panel again. If a card was deactivated and then brought offline (configured off), you will need to activate it again through the Coprocessor Management panel.

There are no z/OS operator commands to vary these devices.
