SPF port issue

[Shahin]

Hi,

We just bought a new 3Com® Baseline Plus Switch 2928 PWR, as you know this Switch has 4 SFP ports for use with fiber obtic cables, we have a problem with these ports. we connect this Switch with one of these ports with a fiber cable to our network and then connect an PC with a CAT 5 cable to othere 24 port, nothing heppend, the PC get no IP from the network DHCP, it get an privet IP 169.245.18.60.

We tought maybe these 4 ports should be enabled before using them, but when we access the Switch we can see that these ports are enabled, and when we connect the switch to our network the green light of the port is on.

our othere switchs are 3COM 4200G  24 ports, does anyone knows if this is an compatibelity issue? or the problem is so thing else? this is some info on the port:

Port State	Enabled	PVID	1
Flow Control	Disabled	Link Type	Access
MDI	Not Support	Speed	Auto
Duplex	Auto	Max MAC Count	No Limit
Broadcast Suppression	100%
Multicast Suppression	100%	Unicast Suppression	100%
Power Save	Disabled

Thanks,

Shahin
