Inserting A Psu; Replacing Esms; Removing An Esm (2U Enclosures) - Lenovo Storage D1212 Hardware Installation And Maintenance Manual

Inserting a PSU

1. Rotate the PSU so that the red release latch and handle are on the left-hand side.
2. Slide the PSU into its bay until the latch clicks home. The enclosure automatically detects the new unit.

Replacing ESMs

The ESM is hot-swappable and therefore removal or replacement may be done by the user while the power
supply is on.
Important:
• Before removing an ESM, make sure that you have a replacement module to insert.
• After installing a new ESM, DHCP is enabled by default. If necessary, configure the static IP address using
the JBOD Configure Utility. You can download the utility from the Lenovo Support Web site.

Removing an ESM (2U Enclosures)

Important: Do not remove this module unless a replacement can be immediately added. The system must
not be operated without all modules in place.
1. Grasp the module latch between the thumb and forefinger and squeeze them together to release the
latch.
2. Pull the latch out to release the module from the enclosure (Figure 96 "ESM Latch Operation " on page
92).
