•
The Fibre Channel indicator shows Fibre Channel activity
when lit. If this indicator fails to light at all, or stays
continually lit without corresponding SCSI bus activity, it
may indicate a problem with the Fibre Channel link.
Verify the Fibre Channel Configuration.
•
The Ethernet indicator signifies Ethernet activity when lit.
If the light fails to flicker, or if it stays continually lit, it
may indicate a problem with the network connection.
Verify the network connection. The port must be
connected to a 10BaseT Ethernet network to function
properly.
Basic Verification
Verify SCSI Bus Configuration
Problems with SCSI bus configuration are common. Basic
operation of a SCSI bus can be checked by using the
configuration menu to view attached SCSI devices. See
Chapter 6
for more information. Other conditions to look for
include:
•
Termination – Problems with termination can cause
intermittent or hard failure. A SCSI bus must be
terminated on both ends, and only both ends.
Termination issues when both narrow and wide devices
are on the same bus are common.
•
Bus Type – Single-Ended devices cannot be mixed with
Differential devices on the same bus. Similarly, Single-
Ended terminators cannot be used on Differential buses,
and Differential terminators cannot be used on a Single-
Ended bus.
•
Device ID – Each device on a SCSI bus must have a unique
ID. Also check the configured ID’s for the FCR200 to
verify these are not in use by other devices on the same
SCSI bus.
•
Cabling – Check SCSI cables to verify they are functional.
SCSI rules for total length, distance between devices, and
stub length must be adhered to. Connections should also
be checked and reseated if necessary.
