Troubleshooting Steps

Troubleshooting Sun Fire 280R Fans

The Sun Fire 280r has one Fan Tray Assembly with 3*120mm Fans.

Use the RSC command environment to display fan Status on the RSC.
Fan failures are logged in the event log. Use the RSC command loghistory to display the event log.

Troubleshooting Sun Fire v480/490 Fans

Sun Fire V480/490 Systems have a CPU Fan Tray on the front and a PCI Fan Tray behind the Disk Backplane.
The CPU and a PCI Fan Trays are not hot-swappable and must be installed while the system is running to ensure proper cooling.

Each System requires a different set of fans trays, open the V480, V490, V490 ROHS:YL, or the V490-2100MHZ System Handbook page for more information.

Troubleshooting Sun Fire Sun Fire V880/V890 Fans

The basic V880/V890 System is equipped with three Fan Trays: a CPU Fan Tray (Right Side), an I/O Fan Tray (Left Side), and an I/O Bridge (Motherboard) Fan Tray. All systems are equipped with this primary set of Fan Trays and redundant cooling from a secondary set of the same fan trays.

In V880/V890 systems configured with the Redundant cooling option, only the Primary Fan Trays are running during normal system operation. If a Primary Fan Tray fails, the environmental monitoring subsystem detects the failure and automatically activates the Secondary Fan Tray.

Each System requires a different set of fans trays, open the V880, V890, V890 ROHS:YL, V890-2100MHZ System Handbook page for more information.
