Cisco 4507 Catalyst switch goes down

[Mohammed Aswath Ali]

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,

  Get on the console port and watch it while it is booting up.  It will usually tell you why it is failing in the logs or messages as it is booting up .
