WARNING Most Fast Ethernet (10/100) Switches/Routers do not support Jumbo Frame and
you will not be able to connect to your 1U4500 after Jumbo Frame is turned on. If
this happens, turn off the 1U4500. Then, power on the 1U4500 and immediately
press and hold the Reset button on the back of the unit for 10 seconds. This will
reset your network settings, password, and turn off Jumbo Frame Support.
NOTE
Before enabling Jumbo Frame Support, please make sure your network equipment
supports Jumbo Frame. If your equipment is incompatible, you might not be able to
connect to your 1U4500. In this case, you have to reset the system back to default
by the holding down front panel reset button for 5 seconds during boot up process.
