Concurrent/dedicated guidelines for FC 8094-001 (lower half) and FC 9094
In some cases you do not need to power down the system in order to change PCI cards. Use the
following guidelines to determine if you should use dedicated or concurrent remove and replace
procedures. If you use concurrent maintenance on a partitioned system, follow the procedures from the
partition that owns the resource. If the resource is not owned, follow the procedure from the primary
partition.
FC 8094-001 (lower half), FC 9094 containing IXS cards:
The IXS cards require dedicated maintenance. Do NOT power down the individual card slot. You can
power down the FC 9094 tower, or the lower half of an FC 8094-001 tower. See FC 8094-001 (lower half),
FC 9094 - Cards (dedicated).
For FC 8094-001 (lower half), FC 9094 cards:
v
Card positions C01 through C09, and C11 through C15 permit card level concurrent maintenance using
HSM. You can power down the individual card slot.
v
If the resource is the load source IOA or the load source IOP, or any other storage IOA/IOP with critical
DASD attached for the system, primary, or secondary partition, follow the on-screen instructions when
you use HSM to power down the IOP or IOA. Instructions to use functions 68 and 69 on the control
panel will be included.
v If the resource is the console IOA or the console IOP for the system or primary partition, you cannot
power down the domain.
v
If the resource is the console IOA or the console IOP for a secondary partition, then power down the
secondary partition and follow the procedure from the primary partition.
CAUTION:
The
circuit card contains lead solder. To avoid the release of lead (Pb) into the environment, do not
burn. Discard the circuit card as instructed by local regulations.
(RSFTC234)
Attention: If removing the cover while powered on, errors may occur due to Electromagnetic Interference.
Attention: All cards are sensitive to electrostatic discharge (see Work with electrostatic discharge-sensitive
parts).
To remove cards concurrently:
1. On the command line, enter the Start System Service Tools command:
STRSST
If you cannot get to SST, select DST (see Dedicated Service Tools (DST) in the iSeries Service
Functions
).
Attention: Do not perform a system IPL to get to DST.
2. Select Start a Service Tool —> Hardware Service Manager —> Packaging hardware resources .
3. Select Hardware contained within package for the Frame ID that contains the IOA or IOP that you
are removing.
4. Find the card position for the IOA or IOP that you are removing and select Concurrent maintenance .
Attention: If multiple resources are shown with the same card position, one or more of these
resources will show a status of Missing (
″
?
″
after the description). Only one resource will be listed as
not missing. Select this resource for the concurrent maintenance operation.
