ASYNC ROUTER AR-P, AR-5, AND SYNC ROUTER USER’S MANUAL

Possible cause #1—Power-source problem. LEDs on front panel are not illuminated.
Suggestion—Verify that the power cable is connected and well seated. Plug something else into the power
source to verify that the wall outlet or power strip is active.
Possible cause #2—The Router cannot read the boot diskette or the boot diskette may be damaged.
Suggestion—Verify that the Router boot diskette is properly loaded into the floppy drive. As the Router
attempts to start, check the LED on the front of the floppy-disk drive to see if the disk is being accessed.
During the normal boot procedure, the disk access LED illuminates briefly during the system power-on
self-test and again for 45 to 60 seconds while the Router system loads.
Upon successful start-up, the Router login prompt displays on the console, and a telnet or RouterVu
session may be established.
NOTE
To telnet (IP only) or routervu (IPX only) to a Router, first run the setaddr program or
complete a successful configuration from the Router console.
If the boot diskette appears to be accessed for the period described above, yet no login prompt displays
on a configured console, or if you are unable to connect with telnet or RouterVu to the Router, try
inserting the backup boot diskette and following the same start-up procedure.
If the disk does not appear to be accessed correctly or the problem is not resolved when using the
backup diskette, call Technical Support.
If the problem is resolved by using the backup boot diskette, your boot diskette is probably damaged.
If the backup boot diskette appears to be accessed for the period described above, and you do not see
a login prompt on an attached console, verify that the console terminal is connected correctly and is
functional.
Possible cause #3 (IP only)—The Router is unable to resolve an IP address or the configured domain name
server is unavailable.
Suggestion—While starting, check the disk access LED to see if the boot diskette is being accessed. During
the normal start-up procedure, the disk access LED illuminates briefly during the system power-on self-
test and again for 45 to 60 seconds while the Router system loads.
If the LED stays lit and you are using the domain name service to resolve hostnames to IP addresses,
there may be a hostname in one of your start-up files that cannot be resolved, and is causing the start-up
script to hang.
Router software stores IP addresses in dotted-quad notation in start-up scripts stored on the boot
diskette. The only way a hostname can be found in a start-up script is if someone edits the Router boot
diskette by hand. If your boot diskette has been modified this way, use a machine that can read and write
DOS-formatted disks to edit the confg.net file on the boot diskette and change any hostnames to dotted-
quad notation.
