Removing the Card
Step 1 Using a T-10 TORX driver tool or flathead
screwdriver, unscrew the top and bottom
captive screws on the card.
Step 2 Simultaneously pivot both ejector levers
away from each other to disengage the

4 Troubleshooting
Check the following:
1. Verify that the LEDs light and go through the
power on self test (POST) when the card is
inserted in the chassis.
2. Verify that the captive screws and ejector
levers are secure.
3. Verify that the POWER LED is on (green). If
the LED off (not green):
a. Verify that there is power to the system.
b. Verify that the card is configured for the
system.
4. If the card is cabled, check to see that the
cables are securely attached and in the correct
location.
