Table 3 Controller status LEDs (continued) Item LED 3 4 MEZZ Indication Flashing amber indicates a controller termination, or the system is inoperative and attention is required. Solid amber indicates that the controller cannot reboot, and that the controller should be replaced. If both the solid amber and solid blue LEDs are lit, the controller has completed a warm removal procedure, and can be safely swapped. Only used on the FC-iSCSI and iSCSI/FCoE controllers (not on the FC controller). Amber LED indicates the FC-iSCSI or iSCSI/FCoE module status that is communicated to the array controller. Slow flashing amber LED indicates an IP address conflict on the management port. Solid amber indicates an FC-iSCSI or iSCSI/FCoE module critical error, or shutdown. 5 Green LED indicates write-back cache status. Slow flashing green LED indicates standby power. Solid green LED indicates cache is good with normal AC power applied. 6 Amber LED indicates DIMM status. The LED is off when DIMM status is good. Slow flashing amber indicates DIMMs are being powered by battery (during AC power loss). Flashing amber with the chassis powered up indicates a degraded battery. Solid amber with the chassis powered up indicates a failed battery. Power supply module Two power supplies provide the necessary operating voltages to all controller enclosure components. If one power supply fails, the remaining power supply is capable of operating the enclosure. (Replace any failed component as soon as possible.) NOTE: If one of the two power supply modules fails, it can be hot-replaced. Figure 9 Power supply 1. Power supply 2. AC input connector 3. Latch 26 P63x0/P65x0 EVA hardware 4.
