RX1330 M3 Upgrade and Maintenance Manual 65
Basic hardware procedures
Redundant power supply
Ê If applicable, connect the mains plugs to power outlets of the rack socket
strip.
I To provide true phase redundancy, the second PSU should be
connected to a different AC power source from the other PSU. If one
AC power source should fail, the server will still continue to run.
Ê Connect the power cords to the PSUs.
Ê Ensure that the status indicator on the PSU is lit green (see section
"Indicator on hot-plug PSUs (slide-in unit)" on page 338).
Figure 11: Example: Locking the cable clamp of a PSU
Ê Pull the cable clamp up (1).
Ê Thread the power cord through the cable clamp (2).
Ê Press the cable clamp down until it engages to secure the cable (3).
I It takes 60 seconds to become a standby mode after connecting a server
to the mains.
