Chassis/slot restrictions

•The module is not supported in the Catalyst 6503 switch chassis.

•The WS-X6748-SFP module can occupy any slot in any other Catalyst 6500 or Catalyst 6500-E chassis with the exception of the Catalyst 6513 chassis where the module must be installed only in slots 9-13. The module will not power up if it is installed in slots 1-8.

•The WS-X6848-SFP-2T/-2TXL operates only in a Catalyst 6500 E-series chassis equipped with a Supervisor Engine 2T-10GE

•Requires that modules be installed in adjacent slots or, if either adjacent slot is unused, you must install a switching-module filler plate (Cisco part numbers WS-X6K-SLOT-CVR-E or SLOTBLANK-09) rather than a blank slot cover (WS-X6K-SLOT-CVR) to maintain an adequate air flow through the chassis.

Fabric connection

•Dual switch-fabric connections:

–Fabric channel 1—Ports 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48

–Fabric channel 2—Ports 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37, 39, 41, 43, 45, 47

Fabric channel speed

20 Gb/sec (dual channel, 40 Gb/sec total)

Module upgrades available

PoE support

Not supported.

Distributed forwarding support

•The WS-X6748-SFP module ships with the WS-F6700-CFC daughter card factory-installed. The module can be upgraded in the field to support dCEF with the installation of a WS-F6700-DFC3A, WS-F6700-DFC3B, WS-F6700-DFC3BXL, WS-F6700-DFC3C, WS-F6700-DFC3CXL, WS-F6K-DFC4-A, or the WS-F6K-DFC4-AXL daughter card.

•The WS-X6848-SFP-2T module ships with the DFC4-A installed; the WS-X6848-TX-2TXL ships with the DFC-4AXL daughter card installed.

Note Refer to the Catalyst 6500 Series DFC3A, DFC3B, and DFC3BXL Installation Note or the Catalyst 6500 Series Distributed Forwarding Card 4 for WS-X68xx Modules Installation Note for additional information and field upgrade procedures.

Pluggable transceivers support

SFP transceivers are supported. Refer to your software release notes to determine which SFP transceivers are supported. See the "1-GB Transceivers" section in Appendix B for additional information on the SFP transceivers.
