Replacing a Card On-Line
Prerequisites for this procedure:
• The card to be replaced uses the same drivers and is of the same type as the card being replaced
• The Power LED is steady ON.
• The Attention LED is steady OFF or is BLINKing (if a user has requested a locate of the slot).
• You are grounded to the chassis of the unit.
CAUTION Working out of sequence, or not completing the actions within each step, could cause the system
to crash. Do not unlock the latch until the after the Attention Button is pressed.
Step 1. Press the Attention Button.
The power LED will start to BLINK, and then turn steady OFF.
If the power LED does not go OFF, then check the hotplugd daemon log file (default:
/var/adm/hotplugd.log ) for errors, and do NOT PROCEED further.
Step 2. Manually unlock the latch (if present).

The CRA performed while doing an Attention Button initiated Replace action is very restrictive, and the
action will not complete (it will fail) to protect critical resources from being impacted. For finer control over
CRA actions, use pdweb or the olrad command.
1. Refer to system hardware documentation for latch instructions.
2. This is the final state of the led. The actual LED behavior is detailed in flowcharts in “Comparing OL*
Methods” on page 84.
