StackWise Cables

Figure 2-11 shows a StackWise stacking cable.

Figure 2-11 StackWise Stacking Cable

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

• STACK-T2-50CM= (0.5-meter cable)
• STACK-T2-1M= (1-meter cable)
• STACK-T2-3M= (3-meter cable)

StackWise Cables Minimum Bend Radius and Coiled Diameter

Table 2-1 specifies the minimum bend radius and coiled diameter for each StackWise cable.

StackWise Adapters

A StackWise adapter must be installed in the stacking port to enable stacking. The StackWise cable connects to the StackWise adapter in the stacking port. For switches ordered with stacking, the StackWise adapters are preinstalled.

If the switches are not ordered with stacking, the adapters must be ordered separately and installed. You can order a StackWise adapter as part of a StackWise stacking upgrade kit (part number C3650-STACK-KIT=) that contains two adapters and a 0.5-m StackWise cable.

Locating the StackWise Adapter Serial Number

If you contact Cisco Technical Assistance regarding a StackWise adapter, you should know the serial number. See Figure 2-12 to find out about how to locate the serial number.

Figure 2-12 Location of the Serial Number on the StackWise Adapter

StackWise Adapter Blanks

A StackWise adapter blank is installed in the stacking port if stacking is not specified at the time of ordering the switch. The StackWise adapter blank is screwed into the stacking port and must be removed and replaced by a StackWise adapter if the port is to be used for stacking. StackWise Adapter Blank shows a StackWise adapter blank.

SFP and SFP+ Module Cable Specifications

Each port must match the wave-length specifications on each 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).

For cabling specifications, refer to the Cisco Transceiver Modules data sheet at:

Identifying a Crossover Cable

To identify a crossover 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 the same color as the wire connected to the pin on the outside of the right plug. (See Figure 2-18.)

Console Port Adapter Pinouts

The console port uses an 8-pin RJ-45 connector, which is described in Table 2-2 and Table 2-3 . If you did not order a console cable, you should provide an RJ-45-to-DB-9 adapter cable to connect the switch console port to a PC console port. You should provide an RF-45-to-DB-25 female DTE adapter if you want to connect the switch console port to a terminal. You can order a kit with an adapter (part number ACS-DSBUASYN=). For console port and adapter pinout information, see Table 2-2 and Table 2-3 .

Table 2-2 lists the pinouts for the console port, the RF-45-to-DB-9 adapter cable, and the console device.

Table 2-3 lists the pinouts for the console port, RJ-45-to-DB-25 female DTE adapter, and the console device.

Note The RJ-45-to-DB-25 female DTE adapter is not supplied with the switch. You can order a kit with the adapter (part number ACS-DSBUASYN=) from Cisco.
