Fibre Channel Pass-Through Module Indicators
The indicator patterns displayed on the optional Fibre Channel pass-through module are dependent
on the specific Fibre Channel daughter card installed in the server module (blade). Cards currently
supported by your system include the Dell 2342M, QME2462, and Emulex LPe1105-M cards. Table 1-1
details the status indicator patterns for these cards, and supersedes Table 1-11 in your Hardware Owner’s
Manual.
Monitor Connections When Installing an Operating System
NOTICE:
If you install an operating system on a server module and your system uses an Avocent Digital Access
KVM module, you must connect the monitor to the KVM module rather than the server module front panel.
NIC Activity LED
The NIC activity LED on the system front panel may occasionally illuminate due to baseboard
management controller (BMC) activity. This is normal behavior for your system.
Throttling of Server Modules
If a power supply or fan module is removed from the system, all server modules (blades) in the system
will be "throttled" until the power supply or fan module is replaced. Throttling reduces the power
consumption of the server modules by changing the processor duty cycle. This will reduce the blade
performance by approximately 50%. The enclosure’s System Event Log (SEL) will indicate if throttling
of the blades has occurred.
If a power supply module or fan module fails but has not been removed, one or more server modules
will be throttled depending on the system configuration. For more information, see the Dell Remote
Access/Modular Chassis User’s Guide.
