Forty-eight 10GE SFP+ Ethernet optical ports

Applicable modules and cables:

• GE optical module
• GE copper module (works at 100 Mbit/s or 1000 Mbit/s)
• 10GE optical module (OSXD22N00 and LE2MXSC80FF0 not supported)

• SFP+ AOC cable
• SFP+ high-speed cable

13

Six 40GE/100GE QSFP28 Ethernet optical ports

• QSFP+ to QSFP+ AOC cable
• QSFP+ to QSFP+ high-speed cable (The cable can only be used as a stack cable or be used to connect peer-link interfaces in an M-LAG.)
• QSFP28 to QSFP28 AOC cable
• QSFP28 to QSFP28 high-speed cable (The cable can only be used as a stack cable or be used to connect peer-link interfaces in an M-LAG.)
  NOTE:

  When a QSFP28 high-speed cable is installed on a 100GE port that works at the rate of 100 Gbit/s, the port supports only the 1 m QSFP28 high-speed cable.

  When a QSFP28 high-speed cable is installed on a 100GE port and the speed 40000 command is run to set the rate to 40 Gbit/s, the port supports 1 m, 3 m, and 5 m QSFP28 high-speed cables.
