Service action
An assert event immediately
followed by a deassert event
indicates that a power cycle of the
system occurred. No service action is
required. If there is no deassert event
immediately following the assert
event, replace the power supply. If
the sensor name is PSU Fault 1,
replace PSU 1. If the sensor name is
PSU Fault 2, replace PSU 2. Go to
"8335-GTB locations" on page 121 to
identify the physical location and
removal and replacement procedure.
If the sensor name is PSU Fault 1,
replace PSU 1. If the sensor name is
PSU Fault 2, replace PSU 2. Go to
"8335-GTB locations" on page 121 to
identify the physical location and
removal and replacement procedure.
Ensure that ac power is supplied to
the rack. Ensure that the system
power cords are plugged tightly into
both the power supply and the rack
PDU unit for both system power
supplies. Go to "8335-GTB locations"
on page 121 to identify the physical
location and removal and
replacement procedure.
Ensure that both power supplies are
securely seated in the system. Go to
"8335-GTB locations" on page 121 to
identify the physical location and
removal and replacement procedure.
