9-18 Upgrading Your Server
POWER SUPPLY UNIT (SAS HOT-PLUG HDD MODEL)
Your server contains one or two power supplies.
The second power supply is optional and provides a redundant configuration that ensures continued
operation of the system in the unlikely event one of the power supplies fails.
Installation
Take the following steps to install a power supply unit:
1.
See the section "Preparing for Installation and Removal" described earlier to prepare.
IMPORTANT:
Be sure to turn off the power. Failure to do so causes
the server to malfunction or fail.
2.
Pull the cable arm toward the rear of the server, and confirm the slot for installing an
optional power supply unit.
3.
Hold and pull the lever of the blank cover and remove the blank cover.
IMPORTANT:
Keep the removed blank cover for future use.
