Gbics on 5500 switch

Hello people,

Maybe someone knows of an issue about using simultaneously more than 2 100mb Gbics on 5500 SFP switch? Basically I've configured 3 5500 in the stuck: 1). 5500 24 SFP ports; 2). 48 ethernet ports and 4 SFP; 3). 24 ethernet ports and 4 SFP. The stuck is working all right, but when I've connected the fiber cables to all  the switches, all the SFP ports were flapping up and down all the time on each switch. Is somebody aware of the problem? Duplex and speed are not the issue.

Thank you in advance.

The 100BASE-X SFP modules can be used only in the 28-port switches. Take a look in the last page:

"† Only for use with Switch 5500-EI 28-Port FX, 3CR17181-91."
