Feature Description
Ports per module 8
Connector type SC or CX4 depending on the type of X2 transceiver installed in the
module.
Cabling distance Depends on the X2 transceiver installed in the module port. Refer to
Appendix B for supported X2 transceiver types and cabling distances.

Maximum frame size Up to 9216 bytes
Supervisor engine support Supported on the following supervisor engines:
• Supervisor Engine 720
Queues per port
• Tx—1p7q4t
• Rx—8q4t
Chassis/slot restrictions
• Not supported in the Catalyst 6503 chassis.
• Supported only in slots 9–13 in the Catalyst 6513 chassis.
• When the WS-X6708-10G module is installed in a Catalyst 6500-E
series chassis or a Catalyst 6500-NEB- A chassis, the configuration
is NEBS 3 compliant (chassis supports operating temperatures up
to 55°C).
• When the WS-X6708-10G module is installed in a Catalyst 6500
non-E series chassis that is equipped with a fan tray 2 and a
2500 W or larger power supply, the configuration is not NEBS 3
compliant (chassis supports operating temperatures up to 40°C
only).
Bus connection Dual 20-Gbps serial channel connections to the switch fabric.
