Figure 14. Installing a sled blank Removing a compute or storage sled from the enclosure Prerequisites 1. Follow the safety guidelines listed in Safety instructions. 2. Power off the sled. CAUTION: Ensure the compute sleds mapped to the storage sleds are powered off. CAUTION: Remove the storage sled only when the hard drive LED is off. NOTE: If the storage sled drive LED indicator is off, it indicates that all the compute sleds mapped to the storage sled are powered off. NOTE: If there are two Fabric C SAS IOMs in powered on state, the management module in the enclosure powers on the storage sleds automatically. Steps 1. To remove a storage or compute sled: NOTE: The procedure to remove a single-width and double-width compute sled is the same. For a storage sled, a. Open the sled removal hatch on the front panel of the sled. b. To release the sled release lever, push the blue release button to the unlock position. For a compute sled, a. To release the sled release lever, push the blue release button on the sled. 2. Hold the sled release lever, pull the sled out of the enclosure. NOTE: Ensure that you install a sled blank if you are removing the sled permanently. Installing and removing system components 29

Follow the safety guidelines listed in
Safety instructions
.
2.
Power off the sled.
CAUTION:
Ensure the compute sleds mapped to the storage sleds are powered off.
CAUTION:
Remove the storage sled only when the hard drive LED is off.
NOTE:
If the storage sled drive LED indicator is off, it indicates that all the compute sleds mapped to the storage
sled are powered off.
NOTE:
If there are two Fabric C SAS IOMs in powered on state, the management module in the enclosure powers on
the storage sleds automatically.
Steps
1.
To remove a storage or compute sled:
NOTE:
The procedure to remove a single-width and double-width compute sled is the same.
For a storage sled,
a.
Open the
sled removal
hatch on the front panel of the sled.
b.
To release the sled release lever, push the blue release button to the unlock position.
For a compute sled,
a.
