Fan population guidelines
•
In a single-processor, nonredundant configuration, fans 5, 6, 7, and 8 cool the server. To enable the
redundant fan mode, install a new fan in the fan bay 1.
•
In a dual-processor configuration, nonrendundant fan mode is not supported; all eight fans are
required.
•
In the redundant fan mode:
o
If one fan rotor fails, the system continues to operate without redundancy. This condition is indicated
by a flashing amber Health LED.
o
If two fan rotors fail, the system shuts down.
•
The minimum fan requirement to make this server bootable is four fans installed in fan bays 5, 6, 7, and
8.
Removing a hot-plug fan blank or module if the server is installed
in a ball-bearing rail system with the cable management arm
CAUTION:
To prevent the potential for thermal damage and system shutdown, ensure that a
functioning server has all feature bays populated with the required component or blank and the
access panel is installed within 60 seconds of being serviced.
1.
Pull down the quick release levers on each side of the server.
WARNING:
To reduce the risk of personal injury or equipment damage, be sure that the rack is
adequately stabilized before extending a component from the rack.
2.
Extend the server on the rack rails until the server rail-release latches engage.
If the server does not extend from the rack, use a T-25 Torx screwdriver to loosen the screws in the lever
housing.
3.
Open the latch, slide the access panel to the rear of the chassis, and then remove the access panel.
If the latch is locked, use a T-15 Torx screwdriver to unlock the latch.
