NOTE: Why would I need to force port scanning?

Some line interface settings are inappropriate for SCM use. During boot up, the SCM scans only those ports set for RS-232 mode. If all of the ports are configured for another mode, (1/2 Duplex or Multi-drop) SCM port scanning is bypassed, and the SCM application cannot be accessed. Use of either of the “Force Port Scanning” operations outlined in Table 1 will force port scanning to occur so the SCM application can be accessed.

LED Error Codes

If an error is detected during the bootup process, an error condition and code are displayed on the LEDs on the face of the Blue Heat/Net Sync.

•The error condition is signaled by a rapidly flashing CPU LED (about 10 to 20 per second).

•The error code is displayed on Port LEDs 1 to 4 as a binary number.
