Hi,
We have cisco 4507 catalyst switch in which end users are connected. today this catalyst switch goes down , i checked the input power was normal but the Switch is not running. All the notification lights like supervisior engine and Fan status lights are showing in RED colur . So i switched off the SMPS and wait for some time and i switched ON , the switch starts running and in 3-4 minutes it again goes down.
Thanks and Best Regards,
