ports must operate at the same speed or you will see an error with a "check speed-group config" message.
The 12-port uplink module has two port groups (ports 1 through 6 [2/1-6], and ports 7 through 12 [2/7-12],
the six-port uplink module has six active ports (ports 1 through 6), and the four-port uplink module has four
active ports (ports 1 through 4).To return the administrative speed to 40 Gigabits, use the
no speed-group
10000 command.
The M12PQ uplink module ports connected with copper cables do not autonegotiate their speeds so you must
set the speed for each port at the connected device by using the
speed 40000 command.

Downlink Connections
For a listing of the transceivers and cables that the optical downlink ports support, see
http://www.cisco.com/c/en/us/support/interfaces-modules/transceiver-modules/products-device-support-tables-list.html
For the 10GBASE-T cables, you use RJ-45 connectors on cables that conform to the specifications in the
following table.
Table 1: Supported 10GBASE-T Cables
Supported Length Cable Type
180 feet (55 m) Category 6
328 feet (100 m) Category 6a
328 feet (100 m) Category 7
328 feet (100 m) Category 7a
Guidelines for Connecting Ports
You can use Quad Small Form-Factor Pluggable Plus (QSFP+) transceivers for uplink connections to other
network devices. You can use RJ-45 connectors for downlink connections to other network devices.
For information about the transceivers currently being used with the switch, use the show inventory all
command.
Prevent damage to the fiber-optic cables that can separate from their cables. Keep the transceivers disconnected
from their fiber-optic cables when installing the transceiver in the line card. Before removing such a transceiver
from the switch, remove the cable from the transceiver.
To maximize the effectiveness and life of your transceivers and optical cables, do the following:
