Lenovo Secure Managed Client - Manual (Page 20)

Installing a power supply unit
To install a replacement PSU, do the following:
DANGER
Do not remove the covers from a PSU. Danger of electric shock exists inside.
Return the PSU to your supplier for repair.
CAUTION:
This procedure should only be performed by qualified service personnel.
Attention:
v Before performing any maintenance on the system, back up the data.
v Handle the PSU carefully and avoid damaging the connector pins. Do not install
the PSU if any pins appear to be bent.
Important: If only one PSU is installed, a blanking plate must be installed to
cover the open PSU slot. Operating the enclosure with any modules missing will
disrupt the airflow and the drives will not receive sufficient cooling. It is
important that all openings are filled before operating the unit.:
Notes:
1.
Follow the instructions in the Secure Managed Client - Storage Array User Guide
User Guide for turning off the system.
2.
If only one PSU is to be installed in the storage system, it must be installed in
the bottom slot (Slot 1). A blanking plate must be fitted to cover the empty
upper slot (Slot 2).
1.
Observe all safety and ESD precautions in the Safety and Warranty Guide.
