Chapter 3. Hot-swapping a power supply You can hot-swap a failed power supply in a DM600S, DM240S, or DM120S disk shelf—nondisruptively replace a power supply in a system that is powered on and serving data (I/O is in progress). When a power supply fails, the system logs a warning message to the system console indicating which power supply failed.

Raise the drive handle to vertical. Use the handle to lift the drive from the drive drawer. Place the drive on a flat, static-free surface and away from magnetic devices. Attention: Possible loss of data access – Magnetic fields can destroy all data on the drive and cause irreparable damage to the drive circuitry.
From the front of the drive shelf, shine a flashlight into the empty drawer slot, and locate the lock- out tumbler for that slot. The lock-out tumbler assembly is a safety feature that prevents you from being able to open more than one drive drawer at one time. Service Guide for DM120S, DM240S, and DM600S...
