All 10/100/1000 ports use standard RJ-45 connectors and Ethernet pinouts.

You can order these StackWise cables (nonhalogen) from your Cisco sales representative:

• STACK-T1-50CM= (0.5-meter cable)

• STACK-T1-1M= (1-meter cable)

• STACK-T1-3M= (3-meter cable)

For cabling specifications, refer to the following notes:

• Cisco SFP and SFP+ Transceiver Module Installation Notes

• Cisco 40-Gigabit QSFP+ Transceiver Modules Installation Note

Cisco Catalyst 2960-X and 2960-XR Switches now support QSFP-4X10G-AOC5M, the 40GQSFP to four 10G SFP+ direct attach breakout Active Optical cable assembly.

Each port must match the wavelength specifications on the other end of the cable, and the cable must not exceed the stipulated cable length. Copper 1000BASE-T SFP module transceivers use standard four twisted-pair, Category 5 cable at lengths up to 328 feet (100 meters).

Cisco QSFP to SFP or SFP+ Adapter (QSA) is a pluggable adapter that converts a QSFP port in to an SFP or SFP+ port. You can connect one of the following SFP+ or SFP module or an SFP+ copper.

The following is the list of Cisco SFP or SFP+ transceiver modules that are currently supported.

• Cisco SFP-10G-SR - Cisco 10GBASE-SR SFP+ Module for Multimode Fiber

• Cisco SFP-10G-SR-S module (S-Class) - Cisco 10GBASE-SR SFP+ Module for Multimode Fiber

• Cisco SFP-10G-LR - Cisco 10GBASE-LR SFP+ Module for Single-Mode Fiber

• Cisco SFP-10G-LR-S module (S-Class) - Cisco 10GBASE-LR SFP+ Module for Single-Mode Fiber

• Cisco SFP-10G-ER - Cisco 10GBASE-ER SFP+ Module for Single-Mode Fiber (extended reach)

• Cisco SFP-10G-ER-S module (S-Class) - Cisco 10GBASE-ER SFP+ Module for Single-Mode Fiber (extended reach)

• Cisco SFP-10G-ZR - Cisco 10GBASE-ZR SFP+ Module for Single-Mode Fiber (up to 80 km reach)

• Cisco SFP-10G-ZR-S module (S-Class) - Cisco 10GBASE-ZR SFP+ Module for Single-Mode Fiber (up to 80 km reach)

Identifying a Crossover Cable

To identify a crossover cable, compare the two modular ends of the cable. Hold the cable ends side-by-side, with the tab at the back. The wire connected to the pin on the outside of the left plug should be a different color from the wire connected to the pin on the inside of the right plug.

The RS-232 console port uses an 8-pin RJ-45 connector. Use an RJ-45-to-DB-9 adapter cable to connect the switch console port to a console PC. You need to provide a RJ-45-to-DB-25 female DTE adapter to connect the switch console port to a terminal.
