When a coprocessor is deactivated through ICSF (Figure 10-36), it cannot be used by applications that run in that system image. The EP11 coprocessor configuration requires a TKE workstation. 

Generally, deactivate an active coprocessor from the ICSF Coprocessor Management panel before it is configured off from the SE. 

Note:  If you do not deactivate the coprocessor first, some jobs might not be rerouted correctly.

The Active/Deactivated status viewed from ICSF Coprocessor Management does not change the Online/Standby status that is set from the z14 ZR1 Support Element.
