Installing the 8-Port asynchronous adapter

The 8-port asynchronous adapter fits into a single Micro Channel slot in the system. Use these steps to install the adapter.

Verify that all users are logged off the system and run the following command:
```
shutdown -F
```
When the shutdown command completes, turn the system power switch to the off position.
Open the system case and insert the 8-port asynchronous adapter into a free Micro Channel slot.
Attach the 78-pin D-shell connector from the 8-port interface cable to the 8-port adapter.
Put the cover panels back on the system unit.
Push the system power switch to the on position. The system will recognize and configure the 8-port adapter during the boot process.
After the boot completes, log in using the root user ID boot process.
```
lsdev -Cc adapter | pg
```

Only those adapters that are in an available state are ready for use by the system.

If the newly installed adapter is not available, then verify:

The adapter is installed correctly into the Micro Channel slot.
All necessary cabling is attached and fitted tightly into place.
Run the command: errpt -a | pg and examine the system error report for problems relating to the adapters.
Run the command: cfgmgr -v | pg. This command will attempt to reconfigure the adapter without rebooting. Observe the paged output for errors.

If running cfgmgr fails, a reboot will be necessary.
