M4250 configuration needed to allow DHCP passthrough
Hello,
I am currently working on an AV system where I have a Crestron CEN-SWPOE-5AC (5-port unmanaged Gigabit Ethernet switch), and I am planning to replace it with a NETGEAR AV Line M4250-26G4F.
My goal is for the NETGEAR switch to behave the same as the Crestron—essentially plug-and-play, operating like an unmanaged switch with no special configuration.
The main switch in the building is a Cisco switch that acts as the DHCP server. With the Crestron switch, my devices receive valid IP addresses in the range of 10.103.19.x (for example, 10.103.19.7 and 10.103.19.23). However, when I connect the NETGEAR switch, the devices are instead receiving 169.254.x.x addresses.
What I am trying to achieve is for the NETGEAR switch to pass DHCP correctly so that my devices receive the same type of IP addresses as they do when connected through the Crestron switch.
Could you please advise what configuration is required on the NETGEAR switch to make it behave like an unmanaged switch and allow proper DHCP assignment from the main Cisco switch?
Thank you in advance for your help.

Hard to imagine an out of the box or factory defaulted M4250-26G4F won't pass traffic, e.g. no DHCP from the primary switch - there is no special configuration required. Especially as its connected at the same location like the previous unmanaged switch.
Start with a basic check if the uplink port (connecting to the main Cisco) has link LED indication at least - regardless if it's a managed or an unmanaged switch.
The minimum I would suggest is to define the M4250-26G4F MAC on the DHCP server, so it will receive an IP address. It's not an inexpensive unmanaged switch, worth taking control, learning -and- properly managing your network. This includes regular firmware updates at least, and ensure it remains reachable from your network admin workstation.
One might guess, also the main Cisco switch acting as a DHCP server, and connecting at least the new Netgear AV switch, should be properly managed, too. Just like all other AV devices.
