Secondary Ethernet
Blue LED that, when lit, indicates that the Status LEDs above the Management Bay module
are displaying status for the Primary or Secondary Ethernet connections.
RJ45 connections that provide the 10/100/1000 Primary (right side) and 10/100 Secondary
(left side) Ethernet connections for each PC blade in the chassis. The numbers correspond
to the blade slot numbers on the front of the chassis.

Power Modules

The R4300 contains two Power Supply Units (PSUs) and a Dual Input Module (DIM). With
the redundancy provided by two PSUs and two power inputs, the R4300 will stay running
even if one PSU fails, or a power input fails, or if a PSU and a power input fail together.
The PSUs are factory-installed, field-replaceable units. Each PSU has a green LED
visible through the fan pack that indicates its powered-on status. If one of the PSUs
fails, the DC POWER status LED on the RMM turns red to indicate a failure, and the
green LED on the failed power supply turns red.
The DIM allows providing redundant power inputs. For best reliability, attach a power
cord to both receptacles, and plug the cords into separate power sources. When using
only one power source, plug it into the receptacle labeled A for best reliability. The
