C. Troubleshooting
a. Reset Button. A manual reset switch is located on the LED end of the
iSCSI Bridge. On the iS520 (pictured below) and the iS550 (Rack
Mountable version) this switch is accessible through a pinhole on the
panel. By pressing this button momentarily, the user can fully reboot the
unit while maintaining previous user configuration data. By pressing and
holding the button for 15 seconds, the unit will reboot and reset to factory
default configuration settings. If you wish to modify settings after the
reset, you will need to re-login.

b. SCSI LED Pulsing. If there are no SCSI targets connected to the iS5xx
iSCSI Bridge by the time the unit fully boots, the “SCSI” LED will
constantly pulse. In this case, turn off all SCSI devices and the iS5xx
iSCSI Bridge. Check to see that the SCSI cables are connected and the
termination is properly placed. If a problem is found, resolve the issue
and power the SCSI devices first and wait for them to be ready. Then
power the iS5xx iSCSI Bridge.
c. Diagnostic Page. On the Diagnostic page of the Web-based Utility there
is an “iS5xx Boot Process Status Codes” section. If the “Processor
Initialization”, “Network Initialization”, “Web Server Initialization”,
“SCSI Initialization” or the “iSCSI Initialization” do NOT display an
“OK” status, reseat the power connector and reboot the unit.
d. Status and Power LEDs. The Status and Power LEDs should turn solid
green after 1 minute of the unit being powered. If this does NOT occur,
make sure the power connectors are properly seated and reboot the unit.
e. Bridge Not Addressable. If you are not able to communicate with
Paralan’s iS5xx iSCSI Bridge from your Management/iSCSI Host
computer, check your IP settings. Changing IP Addresses, Subnet masks,
Gateways, iSCSI Protocol port, and Web port on the Bridge may render it
