• Do not remove a faulty drive assembly until its replacement is ready to be installed.
• Do not keep the cover off an operational enclosure for more than 15 minutes. The reduction in airflow
through the enclosure might cause the enclosure or its components to shut down to protect from
overheating.
About this task
The 2145-92F expansion enclosure supports 92 drives. Figure 110 on page 103 shows an example of a
drive assembly.

Procedure
1. Read all available safety information.
2. Use the slide rails to pull the enclosure out from the rack, as described in “Removing an expansion
enclosure from a rack: 2145-92F ” on page 94.
3. Remove the top cover, as described in “Removing the top cover: 2145-92F ” on page 56.
4. Locate the slot that contains the drive assembly that you want to remove.
Note: When a drive is faulty, the amber fault indicator is lit ( 3 in Figure 110 on page 103). Do not
replace a drive unless the drive fault indicator is on or you are instructed to do so by a x procedure.
When lit, the green indicator shows that activity is occurring on the drive.
A label on the enclosure cover (Figure 111 on page 104) shows the location of the drive slots. The
drive slots are numbered 1-14 from left to right and A-G from the back to the front of the enclosure.
The drive locations are also marked on the enclosure itself. The rows (A-G) are marked on the left and
right edges of the enclosure. The columns (1-14) are marked on the front edge of the enclosure. The
row and column marks are visible when the top cover is removed.
