Connecting High-Speed Stacking Cables
SecureStack B2 Installation Guide 3-11
Thehigh‐speedstackingcablesareoptionalitemsandmustbeorderedseparately.The
B2G124‐48andB2H124‐48supportthreetypesofSecureStackstackingcables:
•C2CAB‐SHORTcabletoconnecttwoadjacentswitchesinthestack.Ifthestackis
inaconfigurationwheretheadjacentswitchesaretoofar
apartfortheSHORT
cables,theLONGcablecanbeusedfortheconnections.
•C2CAB‐LONGcabletoconnectfromthetopswitchtothebottomswitchinthe
stack.YouneedonlyoneC2CAB‐LONGcableperstack.
•C2CAB‐5Mcabletoconnectfromthetopswitchtothebottomswitch
inthestack 
whenthesetwoswitchesarephysicallylocatedinseperatemountingracksand
requirealongercablereach.

Note: The B2G124-24 supports only the C2CAB-SHORT and C2CAB-LONG stacking
cables.
