Powering On the Sun StorEdge 5210
NAS and Expansion Unit(s)
Note – If you are using a UPS, connect the expansion unit(s) and the NAS filer to
the UPS.
Power up the expansion unit(s) first, followed by the Sun StorEdge 5210 NAS. The
redundant power supplies and separate power cords provide fault tolerance if
properly connected.
Warning – The expansion unit(s) must always be powered up and fiber connected
before powering up the main NAS unit. If these instructions are not followed, data
may be lost.
Note – To achieve fault tolerance, the first power cord for the Sun StorEdge 5210
NAS and the first power cord for each expansion unit should be plugged into the
same AC circuit. Plug the second power cord for each unit into a different AC
circuit.
Caution – When you power off the expansion unit(s), wait five seconds before you
power it back on. If you power the expansion unit off and on too quickly,
unexpected results may occur.
