On platforms that include 40GbE interface ports, you can use the ports as a
single 40GbE port or as four 10GbE SFP+ ports.
Each 40GbE port supports four bicolor green/amber LEDs to indicate the
combined link and activity status of each port while operating in both native
40GbE modes (bundled), in addition to in 4 x 10GbE breakout mode (unbundled).
When operating in a native 40GbE mode, all four LEDs operate in unison per
port to indicate the combined link and activity status for a given port. When
operating in a 4 x 10GbE breakout mode, all four LEDs are used independently
to indicate the combined link and activity status for each 10GbE breakout
40GbE ports (i5000/i7000 Series: 3.0-6.0 and i10000/i11000 Series: 3.0-8.0)
default to 40GbE.
On i15000 Series
platforms, the 40GbE ports (1.0-8.0) default to 40GbE.
The cable that you
use when operating at 40GbE is an industry-standard OM3 qualified multi-mode
fiber optic cable with female MPO/MTP connectors at both ends. You must
provide your own cable for 40GbE operation.
You can also disable the 40GbE bundle and use them as individual 10GbE ports
using a QSFP+ breakout cable. This cable has a female MPO/MTP connector at one
end, which connects to the QSFP+ port, and four LC duplex connectors at the
other end, which connect to SFP+ modules on an upstream switch.
If you are using a breakout cable for 10GbE
connectivity, you should use the supported distance as detailed in the
