v No card positions in the CEC permit concurrent maintenance. You must power
down the system to exchange a card. See "Models 840/SB3, FC 8079 (lower
half), FC 9079 Cards — Dedicated" on page 681.
For the FC 9079 I/O Tower cards – except IXS cards:
v Card positions C01 through C07 and C09 through C15 permit concurrent
maintenance using HSM. You can power down the individual card slot, but you
can NOT power down the tower.
v If the resource is the load source IOA or the load source IOP for the system or
primary partition, it must have mirrored protection in order to use concurrent
maintenance.
v If the resource is the load source IOA or the load source IOP for a secondary
partition, then power down the secondary partition and follow the procedure
from the primary partition.
v If the resource is the console IOA or the console IOP for the system or primary
partition you will loose the console once you power down the domain. Follow
the instructions on the screen when you use HSM to power down the IOP or
IOA. They will tell you how to use function 68 and function 69 on the control
panel.
v If the resource is the console IOA or the console IOP for a secondary partition
you will loose the console once you power down the domain. Follow the
procedure from the primary partition, then from the "Work with partition status"
screen do a function 69 for the partition.
v All other card positions require dedicated maintenance. See "Models 840/SB3,
FC 8079 (lower half), FC 9079 Cards — Dedicated" on page 681.
