Fault Tolerance and Access to Power Cutoffs
•
Most NonStop S-series equipment supports two power cords. For fault tolerance,
do not plug the two power cords on any one piece of equipment into the same AC
receptacle. Plug each cord into a different receptacle that is connected to a
different breaker.
•
The AC receptacles to which the server is connected must be accessible to the
operator.
Alternatively, the branch circuit breaker supplying power to each receptacle must
be accessible to the operator and plainly marked to indicate which receptacle the
circuit breaker supports.
Power-On Procedure Using AC Power Cords
1. Find the detachable AC power cords included with your system. See Figure 8-3.
•
AC power cords for enclosures without power shelves are packaged in one of
the boxes included with your system.
•
AC power cords for enclosures with power shelves are preconnected to the
power shelves in the enclosures.
The AC power cord plugs vary depending on the country to which the system is
shipped. For AC power cord plug types and part numbers, see the CSSI Web. See
CSSI Web on page xxiii.
2. For each enclosure in the system, plug one end of a detachable AC power cord
into the appropriate receptacle on the system enclosure:
•
For enclosures that do not have power shelves:
a. Start with the group 01 processor enclosure.
b. Ensure the power interlock on the PMF CRU or IOMF CRU in slot 50 or 55
is fully engaged so that the power cord retainer is aligned with the power
receptacle.
Figure 8-3. AC Power Cord
Caution. Do not plug the other end of the AC power cord into the dedicated outlet at this time.
Doing so immediately powers on the PMF CRU or IOMF CRU.
