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, and can be hot-swapped by
removing the fan pack to access the unit (see Replacing the R4300 Fan Pack on
page 106). 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
DIM is not hot-swappable. Fuses on the DIM can be accessed by powering down the
Cage and removing the fan module.
