Cisco 3750x Stack Cable Length

Sfp and sfp mod ules.

Cisco 3750x stack cable length.

Stacking switches with the same power supply modules together makes it easier to cable the switches. The catalyst 3750 x switches have a stackpower connector for use with cisco stackpower cables to configure a switch power stack that includes up to four switches. Depending on the configurations that you have you might need different sized cables. If you don t specify the length of the stackwise cable the 0 5 meter cable is supplied.

The catalyst 3560 x switch supports the sfp mod ule patch ca ble a 0 5 meter copper passive cable with sfp module connectors at each end. I was wondering if there was a way to see if the port was administrativly down. By adding an xps 2200 expandable power system you can configure a power stack that comprises up to nine switches. Switch 1 stack power cable 2 inserted can i unplug and plug the stackwise cable while device is running power on to test.

Switch 1 stack power cable 2 inserted jan 17 19 59 13 763 utc. Length of cable. Stack cable length 3750 question think of the small but so irritating fact that the stack cables need to make a loop to function properly. You can configure a ring power stack or use the xps 2200 to configure a star topology.

The cable in figure 1 connects a catalyst 3750 x switch to another 3750 x switch in a power stack. Figure b 2 10 gigabit ethernet cx1 copper connector example. The xps 2200 extended power supply for the cisco catalyst 3750 x will not be available until december 2010. If you only use it to make a long chain with 3meter cables then you set yourself up for realy poor performance under load and trouble with split stacks and such things.

I have read that 1m and 3m cables are available in addition to the default 0 5m stackwise cable. Figure 2 10 shows a ring configuration using both of the supplied 0 3 meter stackpower cables and one 1 5 meter cable. Stacking together switches of the same size makes it easier to cable the switches. Is 3m the maximum length available.

In these examples the switches are stacked in a vertical rack or on a table. The 10 gigabit ethernet optical modules use the connectors shown in figure b 3 and figure b 4. The cable in figure 2 is used between a catalyst 3750 x or 3560 x switch and the xps 2200. Figure b 3 figure b 4 and figure b 5 show the sfp module connectors.

At this pint i know its one of the switch stack ports that are the issue. Tested the stack cable on a brand new switch and it detected the cable on both stack ports. Jan 17 19 53 55 295 utc. Basically i am looking to connect switches on different floors utilising the 32gbps connectivity provided.
