I have 4 Mitel 5224's that won't boot up. The Phone turns on and stops booting at "DHCP Discovery" screen. The rev level on these sets is 02.01.00.05. Does anyone know if there is a compatibility issue with the system? The system info is listed below. Thanks!

Mitel 3300
Release 4.1 SP2
Active software load: 10.1.2.16
