Specifications 48 SFP port; 1000BASE-SX, LX/LH, -ZX, -T; 1000BASE-CWDM; LC connecter 6800 Series Gigabit Ethernet fiber and copper modules: WS-X6824-SFP-2T ships with WS-X6824-SFP and WS-F6K-DFC4-E. WS-X6824-SFP-2TXL ships with WS-X6824-SFP and WS-F6K-DFC4-EXL. The front panel of these modules is labeled
WS-X6824-SFP-2T or WS-X6824-SFP-2TXL if it is XL version. Cisco IOS® Software commands display WS-X6824-SFP with either WS-F6K-DFC4-E or WS-F6K-DFC4-EXL. WS-X6848-SFP-2T ships with WS-X6848-SFP and WS-F6K-DFC4-E. WS-X6848-SFP-2TXL ships with WS-X6848-SFP and WS-F6K-DFC4-EXL. The front panel of these modules is labeled WS-X6824-SFP. WS-X6748-SFP and WS-X6848-SFP The WS-X6748-SFP and WS-X6848-SFP Ethernet modules (Figure 2-23) provide 48 1-Gbps full- or half-duplex ports. Table 2-50 lists the module features, and Table 2-50 lists the module physical and environmental specifications. Note The WS-X6848-SFP is the base module. A sticker is placed on the module faceplate identifying it as either a WS-X6848-SFP-2T or WS-X6848-SFP-2TXL depending on whether a WS-F6K-DFC4-A or WS-F6K-DFC4-AXL daughter card is installed on the module.

Queues per port
•With CFC daughter card:
•With DFC daughter card:
•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 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.
•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 module is shipped equipped with either a DFC4-A (WS-X6848-TX-2T) or DFC-4AXL daughter card (WS-X6848-TX-2TXL).
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.
