3.2.3 SCSI-FC Router Modes (SW2)
The DIP switches on SW2 are used to set the operating mode of the SCSI-FC Router.
Note: The SCSI-FC Router’s power must be cycled to effect a change in mode.
Table 3-1 illustrates the modes that are available for the SCSI-FC Router in a connectivity solution and
the specific switch settings that activate each mode.

Table 3-1. DIP Switch Settings for Mode Selection
3.2.3.1 SCSI-FC Router Host Mode
This is the operating mode to be used when the SCSI-FC Router A5814A-003 is connected to the
FC XP family and VA 7100 storage devices.
3.2.3.2 Microcode Revision Mode
In this mode, the SCSI-FC Router microcode revision level will be presented as a status code on
the Status LED. The microcode revision is a three digit number. A decimal separates the first digit
from the second. Example: Revision number 7.60
To run the Microcode Revision mode follow the steps below:
1. Power off the SCSI-FC Router.
2. Set the DIP switches on SW2 to activate ‘microcode revision’ mode.
3. Power on the SCSI-FC Router.
4. Watch the blinking pattern of the Status LED (see Section 3.2.1.4 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.
3.2.3.3 Subsystem Device Check Mode
In this mode, the SCSI-FC Router will talk to the storage device(s) attached to the router
ensuring that proper communication is established.
3.2.3.4 Clear Node Mapping Table Mode
The SCSI-FC Router contains a table of all the nodes on the Fibre Channel and their
corresponding IDs. In this mode the SCSI-FC Router will clear this table enabling a new map
to be established.
