Chapter 4 Connecting Your SCSI Array 4-9
4.5 Powering Up and Checking LEDs
Perform the initial check of the array according to the following procedure:
1. Connect two AC (or DC) power cables to the power and fan modules on the back of
the array.
Caution –
The power cables for SANnet II products are designed only for SANnet II
products and should not be used with other equipment.
2. Power on the array by turning on each power switch.
See “Power-On Sequence” on page 4-30 for the power-up sequence to use when
operating RAID arrays and expansion units. See Appendix B for the power-up
sequence to use when operating standalone SANnet II 200 SCSI JBODs directly
attached to hosts.
3. Check for the following LED activity:
All front-panel LEDs flash green to indicate good operation.
Note –
Whenever media scan is running on a drive, its front-panel LED flashes green.
It is normal for almost all front-panel drive LEDs to flash green unless media scanning
is terminated. For more information, refer to the
SANnet II Family RAID Firmware
User’s Guide .
