•
Port ranges per port group: 1–8, 9–16
Port connector type
SC (optical) or RJ-45 (copper) depending on the type of GBIC
transceiver installed in the module port.
Cabling distance
Depends on the GBIC transceiver installed in the module port. Refer to
Appendix B for supported GBIC transceiver types and supported
cabling distances.
