I am observing the problem with 48 port- 3560G in LAN infrastructure. We have alcatel IP phone which are connected to 3560G switches. Sometimes these IP phone are not getting power up or if i disconnect & connect the IP phone again then it's on powering up. Also sometimes near @ half of the IP phones connected from the switch are working & half not.
After restarting the switch, IP phone gets power up.
What could be the issue ?
