Model 820 - Cards (concurrent)
For use by authorized service providers.
Use this procedure to remove or replace cards concurrently in the Model 820.
Concurrent/dedicated guidelines for Model 820
In some cases, you do not need to power down the system 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.
For all Model 820 cards:
v Card positions C01 through C12 permit 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: All cards are sensitive to electrostatic discharge (see Work with electrostatic discharge-sensitive
parts).
Attention: If removing the cover while powered on, errors may occur due to electromagnetic interference.
To remove cards (concurrently):
1. From the Hardware Service Manager display, select Packaging hardware resources.
2. Select Hardware contained in packaging for the frame ID that you are working on.
3. 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.
4. A listing of the power domain is shown. Find the IOA or IOP that you are removing and select Power
off domain. Everything within the IOA’s or IOP’s power domain will be powered off.
5. To see the status of the power domain, select Display power status.
6. Find the IOA or IOP that you are removing and select Toggle LED blink off/on.
7. Look at the power LED for the card that you are removing to ensure that it is powered off. The power
LED is located to the left and directly above the card slot. If the LED is blinking multiple times per
second (rapidly) or it is off, then the card is powered off.
8. Remove the left side cover. (See Model 820 - Covers.)
9. Remove and label any cables connected to the card.
10. Turn the latches securing the card.
11. Gently pull the card off the system backplane.
This ends the procedure.
