4. Watch the blinking pattern of the Status LED (see Section 2.2.1.4 to decipher the LED
readout).
5. After the revision level is determined, power off the router, return it to its proper
operating mode and power it on.
2.2.3.3 Connection Check Mode
This will check the Fibre Channel connection between the SCSI-FC Routers. In this mode,
the host router will perform a test to ensure that communication to the device router is
operating correctly. If communication cannot be established or if a high number of errors are
reported then the test will fail.
2.2.3.4 Subsystem Device Check Mode
In this mode, the host router will talk to the SCSI device(s) (disk or tape drives) attached to
the device router ensuring that proper communication is established.
2.2.3.5 Clear Node Mapping Table Mode
The host router contains a table of all the nodes on the Fibre Channel and their
corresponding IDs. In this mode, the host router will clear this table enabling a new map to be
established.
2.2.3.6 UW SCSI-FC Router Disk Mode
This is the normal operating mode of the device SCSI-FC Router when SCSI Ultra Wide disk
drive(s) are attached. Two device routers cannot exist simultaneously on the same serial loop.
2.2.3.7 UW SCSI-FC Router Tape Mode
This is the normal operating mode of the device SCSI-FC Router when SCSI Ultra Wide tape
drive(s) are attached. Two device routers cannot exist simultaneously on the same serial loop.
2.2.3.8 FW SCSI-FC Router Disk Mode
This is the normal operating mode of the device SCSI-FC Router when SCSI Fast Wide disk
drive(s) are attached. Two device routers cannot exist simultaneously on the same serial loop.
For the device router to operate properly, when used with a SCSI Fast and Wide disk storage
system, it must be set to the FW setting. Since most RAID or JBOD storage systems use a
converter, the Ultra Wide setting cannot be used. If the disk drives attached have no converter or if
they are simple disk drives then the SCSI-FC Router will be able to setup the proper operating speed
with each disk drive attached.
2.2.3.9 FW SCSI-FC Router Tape Mode
This is the normal operating mode of the device SCSI-FC Router when SCSI Fast Wide tape
drive(s) are attached. Two device routers cannot exist simultaneously on the same serial loop.
For the device router to operate properly, when used with a SCSI Fast and Wide tape drive
storage system, it must be set to the FW setting. Since most RAID or JBOD storage systems use a
converter, the Ultra Wide setting cannot be used. If the tape drives attached have no converter or if
they are simple tape drives then the SCSI-FC Router will be able to setup the proper operating speed
with each tape drive attached.
