Is the link up? If not, try to statically assign the port speed according to the speed supported by the device i.e. if the printer has 100mbit network card, try assigning the switch port to static 100mbit.  I've had issues with auto negotiation on N1100-ON series myself.
Hi, I want to discuss about my network issue, after changed existing Net Gear and HP Switch to N1148T-ON and N1124T-ON everything is working but my printer and DVR I am not able to ping (Not working), I checked that particular port and cable its working perfectly please help me for this ASAP Thanks in advance.
