  1. Heat is a legitimate concern. Make sure all the cooling fans are working properly.
  2. Check for network loops. If your switch supports STP (Spanning Tree Protocol), try enabling it--and if it's already enabled, try disabling it! Not all implementations are bug-free.
  3. If all else fails, reset the switch to factory defaults and configure it from scratch. Configurations can become corrupted--especially if the device has undergone firmware changes.

I have a gs724t and need to add a gs748t, what cable do I use to link them together??

Most switches are smart enough to detect and reverse logic if the wrong cable is used. If you want to be correct you would use a crossover cable.

Computer to computer, router, or extender (crossover)
Computer to switch or hub (straight through)
Switch/Hub to Switch/Hub (crossover)

First, make sure your switch and PC are in the same broadcast domain/subnet, and that there is a DHCP server in operation.

Second, make sure you are following the "factory reset" procedure correctly (

Netgear switch GS748T smart switch needs reboot very frequent

(Answering a six-year-old question...)

From the description--especially the part about having "spanning tree" disabled--the first thing that I would do is look for network loops. STP/RSTP ("spanning tree") detects these loops, and disables ports to prevent packet storms. If that is the problem, enabling STP should clear it up--but you also want to make sure you want those loops in the first place.
