Chassis CMM Does Not Allocate Enough Power
to the Netra T4-1B Server Module (CR 7141886)
When power is not properly allocated, the server module operates at only about 60%
of capacity.
Workaround: If you update the server module system firmware to 8.1.4.f or newer.
PSH Might Not Clear a Retired Cache Line on a
Replaced Motherboard (CR 7031216)
When the enclosure is replaced to repair faulty cache on the motherboard, PSH might
not clear the cache on the replacement. The cache line remains disabled.
Workaround: Manually clear the disabled cache line by typing
# fmadm repaired fmri | label
# fmadm replaced fmri | label

2-Meter USB Cable Length Limit (7048419)

The server module has three USB ports:
Port 1 and 2, accessible through a dongle that is attached to the front UCP
■
connector.
Port 5, located on the rear of the motherboard (intended for a USB flash drive).
■
Workaround: If you connect USB devices to ports 1 or 2, ensure that the cable does
not exceed 2 meters (approximately 6.5 feet).
Uncorrectable L2 Cache Errors Are Sometimes
Reported as Core Faults Without any Cache Line
Retirement (CR 7071237 and CR 7071974)
When a processor cache line encounters an uncorrectable error, the fault manager
should retire the cache line that is involved in the error. However, the fault manager
might not succeed in retiring the faulty cache line and instead report the entire core
or processor as faulted.
