Check The Cpu Led - Avaya IP500 Installation Manual

8.7 Check the CPU LED

IP500/IP500 V2 Installation
IP Office 8.0
During normal operation, the CPU LED on the rear of the IP500 control unit
should be green.
· Note
New IP Office 500 control units are supplied with a base software level
of 4.0.0. The CPU LED on these units will flash red until the unit is
upgraded to the required level of released IP Office core software.
Normal Power On Sequence
When power to the control unit is switched on, the normal sequence for the
CPU LED is as follows.
1. Steady Red for 3 seconds
2. Off for 10 seconds
3. Flashing alternate red/green for 4 seconds.
4. The LED should be steady green following successful start up. Note that
the IP500 cards on the front of the control unit may still be going
through their own start up process.
· Flashing RED
A flashing red CPU LED at this stage indicates an error. The most
likely cause is a missing Feature Key card.
