Caution – Do not remove a card unless all of the LEDs are in the proper states. If
you remove a card when any of the LEDs are not in the proper state, it may lead to
unpredictable results. It may take several seconds or minutes for the LEDs to
transition to the proper states.
Caution – Do not attempt to hot-swap any other cards until you see that the first
card has been fully deactivated. Hot-swapping more than one card at the same time
may lead to unpredictable results. In some situations, it could several minutes for
the card to completely deactivate.
Note – If the server is set to the default full hot-swap mode, unlocking the ejection
levers automatically starts the cfgadm unconfigure operation. If you decide that
you do not want to remove the card, you must wait until the LEDs are in the correct
state (as shown in
ejection levers again in order to start the cfgadm configure operation. Simply
locking the ejection levers after unlocking them will not start the driver attachment
process.
13. When it is safe to remove the card, disconnect any cables connected to the card.
14. Press outward on the two ejection levers on the card to unseat the card from the
card cage.
15. Carefully slide the card out of the slot and place it on the electrostatic discharge
mat.
If you are hot-swapping an alarm card, you may notice one thing that is unique to
the alarm card. If you enter the cfgadm command after you have removed the alarm
card, you will see disconnected under the Receptacle column. For all other cards,
after you have removed the card, you should see empty under the Receptacle
column.
16. Perform any additional card-specific hardware procedures, if necessary.
For example, you may want to remove the PMC(s) from a faulty satellite CPU or I/O
card and install it on the replacement card later on. Refer to the documentation that
you received with your card for more information.
17. Secure a blank filler panel over the empty I/O slots, if necessary.
If you are not going to replace the card right away, you must install a blank filler
panel over the opening to ensure proper airflow in the system. The slot filler panel is
secured to the card cage using two screws, one at the top of the filler panel, the other
at the bottom.
