Analysis
A switch supporting PoE has certain specifications in PoE power supply. When the total supplied power
exceeds the maximum power supply capacity of the switch, the switch automatically disconnects some
ports with lower priority. Therefore, APs attached to these ports will restart.
Check the log information on the switch:
#Apr 6 11:26:44:368 2000 YXY-WLAN-04 DRV_DEM/5/POE WARNING:- 1 -Power budget exceeded
#Apr 6 11:26:44:418 2000 YXY-WLAN-04 DRV_DEM/5/POE WARNING:- 1 -Poe function of Ethernet1/0/6
is disabled.
The first line indicates the total supplied power exceeds the maximum power supply capacity of the
switch. The second line indicates the switch stops supplying power through an interface.
Solution
Add more PoE switches or use PoE modules to separately supply power to the APs.
The power supply issue needs to be fully considered for network planning. The WX3000 series unified
switches have the PoE power supply requirements:
z The WX3024 supports 24-port PoE+ with the maximum output power of 25 W per port, provides a
maximum of 370 W internal power supply, supports PoE+ for 14 ports simultaneously, and
supports PoE+ for 24 ports when it is used with an RPS unit.
z The WX3010 supports 8-port PoE+ with the maximum output power of 25 W per port, provides a
maximum of 125 W internal power supply, supports PoE+ for 4 ports simultaneously, supports PoE
(802.3af) on eight ports, and supports PoE for eight ports simultaneously.
z The WX3008 supports 4-port PoE+ with the maximum output power of 25 W per port, provides a
maximum of 125 W internal power supply, supports PoE+ for 4 ports simultaneously, supports PoE
(802.3af) on four ports, and supports PoE for four ports simultaneously.
The WX6103 Access Controller Switch Interface Board Cannot Be
Started
Symptom
The WX6103 access controller switch interface board cannot be started, and you cannot enter the user
prompt.
Solution
Check that:
1) The switch interface board is well inserted into the chassis.
2) If the LEDs of the switch interface board are all off, the switch interface board may not be powered
on. If the LEDs are all on, the switch interface board may be faulty or is not well inserted into the
chassis. Re-insert the switch interface board in the latter case.
3) The hardware components on the switch interface board are normal. For example, check whether
the heat sink components are properly connected or fall off. In case of a falloff, re-install the
component with the specific material.
