Power Supply Unit
The second power supply unit in a Netra CT 810 server is hot-swappable, as
described in
Section 1.3, “FRU Categories” on page 1-3
. The remaining power supply
unit in a Netra CT 810 server and the lone power supply unit in a Netra CT 410
server are cold-swappable. If you are replacing a
hot-swappable
power supply unit,
then follow the instructions in this section; if you are replacing a
cold-swappable
power supply unit, then go to
Section 10.2, “Cold-Swappable Power Supply Unit”
on page 10-5
.
Note that your Netra CT 810 server continues to operate normally with only one
power supply unit; however, you do not have complete redundancy for the power
supplies until you replace the failed power supply unit.
The newest part number for the power supply unit is F300-1767. Older power
supply units with part numbers F300-1535 can be used.
8.4.1
Removing a Hot-Swappable Power Supply Unit
1. Attach the antistatic wrist strap.
See
Section 1.2, “Attaching the Antistatic Wrist Strap” on page 1-2
.
2. Determine the state of the power supply unit that you want to remove.
You might have to get troubleshooting information from the LEDs on the power
supply unit to determine the state. See
Section 4.6, “Troubleshooting a Power Supply
Using the Power Supply Unit LEDs” on page 4-18
for information.
3. Verify that the power supply unit that you want to remove is hot-swappable.
Use the power supply unit (PSU) LEDs on the
system status panel
to locate the power
supply unit that can be removed.
FIGURE 8-12
shows the location of the power supply
unit LEDs on the Netra CT 810 server system status panel.
In a redundant system, a power supply unit is hot-swappable and can be removed if
the amber Okay to Remove LED (
) on the
system status panel
is ON.
Note –
Do
not
remove a power supply unit if the amber Okay to Remove LED (
)
on the system status panel is OFF; that means that the power supply unit is
not
hot-
swappable, and your server power would turn off if you removed it.
