You can install a VIM5 versatile interface module in a dedicated slot in the front panel of the ExtremeSwitching VSP 4900 Series switch to provide 10/25/40G dedicated high speed ports. The front panel of every VSP 4900 switch provides one slot to install the following:
VIM5-4X versatile interface module that provides four 10-GbE (SFP+) ports.
VIM5-4XE versatile interface module that provides four 10-GbE (SFP+) ports, LRM/MACsec capable.
VIM5-2Y versatile interface module that provides two 25-GbE (SFP28) ports.
VIM5-4Y versatile interface modulethat provides four 25-GbE (SFP28) ports.
VIM5-4YE versatile interface module that provides four 25-GbE (SFP28) MACsec capable ports.
VIM5-2Q versatile interface module that provides two 40-GbE (QSFP) ports.
For 24 and 48-port models, the VIM5 ports are 2/1, 2/2, 2/3, 2/4 depending on the VIM installed.
VIM5s are ordered separately. Each VIM5 label can be found on the bottom side of the device, as seen in the following figure:
