By connecting the switches with power stack cables you can manage the power supplies of up to four stack members as a one large power supply that provides power to all switches and to the powered devices connected to switch ports.
Cisco 3850 power stack cable lengths.
The example below shows how to properly connect a stack of six 3850 switches together with a power stack connection example.
Depending on the physical setup of the infrastructure different lengths of stacking cable may be needed.
Each port must match the wavelength specifications on the other end of the cable and the cable must not exceed the stipulated cable length.
Depending on the configurations that you have you might need different sized cables.
Stackpower cables have color bands on the cable ends.
The process will be similar for stacks of 2 3 4 5 7 8 and 9 switches.
Stacking cables are mandatory for stacking architecture.
If you do not specify the length of the stackwise cable the 0 5 meter cable is supplied.
The cable in the figure connects a switch to another switch in a power stack or with an xps.
Since power supplies are most effective when running at 30 to 90 of their maximum load taking some of the power.
The process will be similar for stacks of 2 3 4 5 7 8 and 9 switches.
Stacking cables that support cisco catalyst 3850 series switches can be used for the 9300 modular uplink models making them backward compatible.
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.
The example below shows how to properly connect a stack of six 3850 switches together with a power stack connection example.
Stackpower cable for use.
I spaced the switches 1u apart with the default stack cable.
Cisco 3850 stack power cables.
I personally think a cable management bar in the back would only get in the way and wouldn t be needed.
Stacking switches with the same power supply modules together makes it easier to cable the switches.
So besides the cisco catalyst 3850 switches you should prepare the cisco 3850 stack wise cables and stack power cables.
The cable end with the green band can connect only to a switch.
Depending on the configurations that you have you might need different sized cables.
Stack t1 50cm stackwise stacking cable with a 0 5 m length stack t1 1m stackwise stacking cable with a 1 0 m length stack t1 3m stackwise stacking cable with a 3 0 m length stack power cable recommended cab spwr 30cm stack power cable with a 30cm length cab spwr 150cm stack power cable with a 150cm length power supply pwr c1 350wac.
If you do not specify the length of the stackwise cable the 0 5 meter cable is supplied.
Don t know if this will help but i just installed a 3850 two switch stack.
However the cable is pretty rigid and not that flexible.
Depending on the configurations that you have you might need different sized cables.
Really no need to tie or dress it.
