Message
Probable cause
Problems were encountered when the software attempted to write to the memory of the FRU specified in
the error message. The return code is for internal use only. This is a serious FRU hardware problem.
The FRU-Id value is composed of a FRU-type string and an optional number to identify the unit, slot, or
port. The FRU-Id value can be:
• Switch for fixed port count switches.
• Slot 1 through Slot 10 for the Core Switch 2/64 and SAN Director 2/128.
• PS 1 through PS 4 (power supplies) for the Core Switch 2/64 and SAN Director 2/128, or PS 1
through PS 2 for the SAN Switch 2/32 and SAN Switch 4/32. The power supplies on the SAN Switch
2/8V and the SAN Switch 2/16V are not field replaceable.
• Fan 1 through Fan 3 for the Core Switch 2/64 SAN Director 2/128, and SAN Switch 4/32 (six
fans in three FRUs). Fan 1 through Fan 6 for the SAN Switch 2/32 (six fans in three FRUs). The fans
on the SAN Switch 2/8V and the SAN Switch 2/16V are not field replaceable.
• WWN 1 or WWN 2 for the Core Switch 2/64 and SAN Director 2/128. Only bladed switches have
removable WWN cards. All other switches have a non-removable WWN component on the main
logic board.
The SAN Switch 2/8V has one power supply and three fans, and the SAN Switch 2/16V has two power
supplies and four fans. Values for the individual fans and power supplies for these switches may appear,
but these parts cannot be replaced. The switch itself is a FRU.
Recommended action
1. Try reseating the FRU, if possible.
2. If this fails to correct the error, replace the specified unit.
