StackWise Ports

StackWise ports are used to connect switches in StackWise stacking configurations. The Catalyst 3850 switch ships with a 0.5-meter StackWise cable that you can use to connect the StackWise ports. For more information on StackWise cables, see StackWise Cables, page B-5.

Caution Use only approved cables, and connect only to similar Cisco equipment. Equipment might be damaged if connected to nonapproved Cisco cables or equipment.

Power Supply Modules

The 24- and 48-port switches are powered through one or two internal power supply modules.

Supported power supply modules:

•PWR-C1-350WAC

•PWR-C1-715WAC

•PWR-C1-1100WAC

•PWR-C1-440WDC

The switch has two internal power supply module slots. You can use two AC modules, two DC modules, a mixed configuration of one AC and one DC power supply module, or one power supply module and a blank module.

The switch can operate with either one or two active power supply modules or with power supplied by a stack. A Catalyst 3850 switch that is in a StackPower stack can operate with power supplied by other switches in the stack.

Table 1-1show the default power supply modules that ship with each switch model. All power supply modules (except the blank modules) have internal fans. All switches ship with a blank power supply module in the second power supply slot.

Caution Do not operate the switch with one power supply module slot empty. For proper chassis cooling, both power supply module slots must be populated with either a power supply or a blank module.

The 350-W and 715-W AC power supply modules are autoranging units that support input voltages between 100 and 240 VAC. The 1100-W power supply module is an autoranging unit that supports input voltages between 115 and 240 VAC. The 440-W DC power supply module has dual input feeds (A and B) and supports input voltages between 36 and 72 VDC. The output voltage range is 51–57 V.

Each AC power supply module has a power cord for connection to an AC power outlet. The 1100-W and 715-W modules use a 16-AWG cord (only North America). All other modules use an 18-AWG cord. The DC-power supply module must be wired to a DC-power source.

Table 1-13, Table 1-14, and Table 1-15shows the PoE available and PoE requirements for Catalyst 3850 switches.
