MS108EUP fails to pass/provide DHCP

Thank you Schumaku for the prompt reply. I may have used a poor choice of words to describe the switch as in "dumb" mode. What I was referring to was the switch is in near basic basic configuration where I did not explicitly changed options or modified settings other than a couple of general options that should not interfere with IP addresses. System is as follows:

Pfsense firewall is set to its most basic configuration: no VLANs, LAN port configured with DHCP server using 192.168.1.X IP pool of addresses. LAN port of the firewall connected to one port in the switch. All devices connected to the switch are able to obtain an IP address without any problems when the switch is in its functional state.

Switch config: near out-of-the box configuration, IP configured via DHCP. QoS default (802.1P/DSCP). VLANs "disabled" (default option of No VLANs in the VLAN options). System time configured to SNTP using the default Netgear timing server. Out of the 8 ports, 3 are running full 2.5G (including the upstream port to the Firewall appliance), 3 other ports are only running at 1Gbps. 2 ports are unused.

If it helps, the switch is running firmware 1.0.1.9.
