Supervisor Engine 2T-10GE
With Supervisor Engine 2T-10GE —Cisco IOS Release
15.2(1)SY or later
With a WS-F6K-DFC4-A / AXL daughter card:
• Tx—1p3q8t
• Rx—2q8t
C6800-48P-SFP/ SFP-XL operates only in a Cisco Catalyst
6807-XL and a Cisco Catalyst 6500 E-series chassis equipped
with a Supervisor Engine 2T-10GE.
Modules must be installed in adjacent slots. To maintain adequate
air flow through the chassis, install a switching-module filler
plate (Cisco part number WS-X6K-SLOT-CVR-E=) in unused
slots, rather than a blank slot cover (Cisco part number
WS-X6K-SLOT-CVR=).
Dual switch-fabric connections:
• Fabric channel 1—Even ports 2 to 48.
• Fabric channel 2—Odd ports 1 to 47.
