1-16 Sun StorEdge D2 Array Installation, Operation, and Service Manual • February 2002
1.7.2 Power Supplies
The Sun StorEdge D2 array has two hot-pluggable and interchangeable DC power
supplies. They provide power to the internal components by converting incoming
AC voltage to DC voltage. With these redundant power supplies, one power supply
maintains electrical power to the system if the other power supply fails. Both power
supplies are removable canisters that slide into one of two slots in the back of the
system. Each canister has a locking handle, a power status LED, an AC power cord
connector, and a power switch (
