the same time. Otherwise, the equipment might overheat.
3. Determine which drive drawer you need to replace, as follows:
• If the power is on, the blue Service Action Allowed LED indicates the cable chain you need to disconnect.

Cable chain
2 Vertical connector (connected to the midplane)
3 Horizontal connector (connected to the drive drawer)
The top cable chain is attached to drive drawer 1. The bottom cable chain is attached to drive drawer 5.

Attention: Possible hardware damage — If the drive tray is powered on, the cable chain is energized until both ends are
unplugged. To avoid shorting out the equipment, do not allow the unplugged cable chain connector to touch the metal
chassis if the other end of the cable chain is still plugged in.
