The normal boot sequence and LED states are as follows:
1. The power light comes on.
2. After approximately 10 seconds, the speaker beeps once and the diskette
drive light comes on.
3. After approximately 5 seconds, the diskette light goes off, and the Test
LED comes on. Diagnostics and startup can take 3 to 7 minutes
depending upon the model of your 5500 control unit, its configuration and
its state. Normally, the power LED appears green and the test LED
appears yellow for approximately 3 to 7 minutes. During this time, the
unit conducts system diagnostics, verifying operation of the twinax
controller card, LAN adapters, and RS-232 WAN ports.
4. Near the end of the startup, the twinax-attached PCs will beep 3 times.
Boot or reboot the twinax attached workstation.
Note: The PC workstation will beep 3 times signaling a successful
connection to the 5500 control unit.
5. The system is ready when the Ready LED is yellow and the Test LED is
off (not lighted). The unit is now operational and ready for initial
configuration as described in "Configuring the 5500 Express IP Control
Unit" on page 55.
