Those ports allow for either Fiber or STP (RJ45) connections. If you notice the SPF module ports have the respective f21, f22, f23, f24 they match the t21, t22, t23, and t24 ports. The F = Fiber and the T=Twisted Pair. See the excerpt below of the manual for the netgear switch: (Ref: http://kb.netgear.com/app/ products/m odel/a_id/ 2465) Download the Administrators Manual from this page.
Gigabit Module Bay
You can install an SFP Gigabit Ethernet module in the gigabit module bays.
Four ports on the switch can be used for either STP (RJ-45) or SFP (fiber) cable.
However, both port types cannot be used at the same time. The switch selects the
first connected interface. If both connectors are plugged, the SFP interface
operates normally and disables the copper interface.
