44 Installing the XS-3900
Powering Up the XS-3900
When powering up, the array follows a specific sequence of LED patterns
showing the boot progress, and following a successful boot will provide extensive
status information. The normal boot sequence is as follows:
1. The green status LED will light first, showing a steady flashing while the
unit boots. In the event of a boot failure, this LED will change to flashing
red.
2. The Ethernet Link/Activity LEDs on the underside of the array will light
for those ports connected to the network.
3. All IAP radio LEDs will light simultaneously.
4. While the array is booting, a sequential LED pattern will cycle through all
the radio LEDs.
5. When the array completes boot, the status LED will show a steady green,
and all radio lights will show the current state of those radios.
