Impact This configuration can lead to a greater system interruption hazard during failover of the RTS than a single power source configured into a single RTU with one RTS connected. Contributing Factors Configuring a single source into 2 RTS units installed into the same RTU is not recommended by SUN. Symptoms Sun Fire Servers (3800/4800/4810/6800) may encounter power failover issues when system RTS/RTU units are configured from a single power source. This configuration can lead to a greater system interruption hazard during failover of the RTS than a single power source configured into a single RTU with one RTS connected.
There are no software commands for determining whether a system has an affected RTS or not. Please follow these steps to determine if a system or cabinet is affected:
A: Two independent sources of power connected to the RTU. B: One source of power connected to one RTS in a RTU with the other RTS either not installed or left disconnected.

Root Cause
Workaround For Sun Fire 3800/4800/4810/6800 systems with a single source input connected to two RTS's in a single RTU box, bring the system into a supported configuration or inform the customer of the risks associated with 300-1396-05 (or below) RTS units.
http://www.sun.com/blueprints/0901/sunfireconfig.pdf RTS units are highly reliable. The possibility of a failover issue and an unplanned outage in the Single Source to Dual RTS configuration is actually greater than the possibility of an RTS failure causing an outage.
