Sayfayı YazdırPower subsystem
The x3850 X6 and x3950 X6 systems are designed with modular power subsystem. This
design allows for one to choose the optimally-sized power supplies for your system
configuration. The power subsystem is designed around two zones to ensure that in the event
of a loss of a power feed the system continues to function.
Power supplies are numbered (from left to right) 4, 3, 2, and 1, as shown in Figure 16. The
even power supplies are in one power feed zone, and the odd power supplies are in the other
power feed zone.
Figure 16 Power supplies
For the power subsystem, keep in mind the following notes:
Power supply unites (PSUs) are installed in the following order for the x3850 X6:
a. Power supply bay 3
b. Power supply bay 2
c. Power supply bays 1 and 4
If systems have mixed 900W and 1400W PSUs, make sure the PSUs are populated
correctly: 1400W PSUs in the odd numbered bays and 900W PSUs in the even numbered
bays.
A reboot is required to recalibrate system power any time settings are changed that impact
overall power draw on the system.
Systems plugged into 110/120V power have their 1400W PSUs operate at 900W. Keep
this in mind when calculating the system power.
When changing power redundancy settings, be aware that this impacts overall power
requirements for a system. Setting a system to a power redundancy level that its input load
cannot support can cause the system to go into a reboot loop. If the system fails to power
and reboot after the "Recalibrating System Power ..." message displays on the screen,
complete the following steps:
a. Log in to the IMM.
b. Click the Server Power Management tab, as shown in Figure 17 on page 20.
c. Select Power Supply Redundancy. The Power Policies window opens, as shown in
Figure 18 on page 20.
d. Make sure there is enough power to power the system.
e. Make sure there is enough power to run the system with the level of redundancy
required.
