Owners Manual

● As an alternative to using the PowerVault Manager, you can run the CLI show system command to view the health of the
system and its components. If any component has a problem, the system health will be Degraded, Fault, or Unknown. If
you discover a problem component, follow the actions in its Health Recommendations field to resolve the problem.
● Monitor event notification — With event notification configured and enabled, use the PowerVault Manager to view the
event log, or run the CLI show events detail command to see details for events.
● Check Fault LED (back of enclosure on controller module or IOM face plate): Amber = Fault condition.
● Check that the OK LED (back of enclosure) is off.

1-This model uses a qualified FC SFP option within the CNC ports (used for host connections). When in FC mode, the SFPs
must be a qualified 16Gb fiber-optic option. A 16 Gb/s SFP can run at 16 Gb/s, 8 Gb/s, 4 Gb/s, or auto-negotiate its link speed.
2-This model uses a qualified 10 GbE iSCSI option within the controller module CNC ports (used for host connections).
3-CNC ports support same-type or mixed-type SFPs in combination.
4-This model supports 10 Gb/s or 1 Gb/s speeds (used for iSCSI host connections).
5-This model uses SFF-8644 connectors and qualified cable options for host connections.
