How to Identify Cards and Slots
Note – Internal access to the Sun Fire V890 system is restricted to qualified service
personnel. Installation procedures for internal components are covered in the Sun
Fire V890 Server Service Manual, which is included on the Sun Fire V890 Server Online
Documentation CD.
Caution – Hazardous energy levels are present inside the system when the system
remains connected to a power source, regardless of the keyswitch position. Also,
hazardous energy levels are present in the system’s batteries even when all AC
power cords are disconnected. Follow the safety procedures in your system Owner’s
Guide or Service Manual.
Caution – Avoid keeping doors open for extended periods of time while the system
is operating. All doors must be closed to prevent automatic thermal shutdown.
Identifying a Card Inside the System
1. Check the system front panel LEDs.
If a card is faulty, a directional LED on the front panel display turns on and points to
the side of the system where the card is located. If a card is ready for you to remove
after a successful DR operation, the OK-to-Remove LED turns on and a directional
LED indicates the location of the card. For additional details on the system front
panel LEDs, see the Sun Fire V890 Server Owner’s Guide.
2. Open the appropriate side access door and check the interior status LEDs.
Inside the system, a Fault LED turns on to indicate which slot contains the faulty
card. After a successful DR remove operation, an OK-to-Remove LED turns on to
indicate which slot contains the card to be removed. For more information, see
“About the Status LEDs” on page 12.
