EonStor A16E-G2130-4 Installation and Hardware Reference Manual

5.5.2 Replacing the PSU Module

WARNING!

Before you insert a new PSU, be sure that it has the same warning label on its extraction handle as that shown on the lever of a remaining PSU. Double-check to avoid mixing a similar yet different PSU of another EonStor series.

To replace a PSU, please follow these steps:

Step 1. Power off the PSU. The power switch is located on each PSU’s rear- facing panel. (See Figure 5-9)

Step 2. Disconnect the power cord that connects the PSU to the main power source.

Step 3. Remove the retention screw that secures the rejection handle to the chassis. (See Figure 5-10:Removing the PSU Retention Screw.)
