Chapter 1 Product Overview

Rear Panel

For Catalyst 3650 switches where stacking is specified, StackWise adapters are preinstalled in the StackWise ports, and optional StackWise cables can be ordered. When stacking is not specified, but is required, the StackWise adapter blanks must be removed and StackWise adapters installed. For more information on connecting switches for stacking see “Connecting to the StackWise Ports” section on page 2-15.

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

Note You cannot have a switch stack containing a mix of Catalyst 3650 and Catalyst 3850 switches.

Power Supply Modules

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

Supported power supply modules:

•PWR-C2-250WAC=

•PWR-C2-640WAC=

•PWR-C2-1025WAC=

•PWR-C2-640WDC=

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 cover. The switch can operate with either one or two active power supply modules.

Table 1-1shows the default power supply modules that ship with each switch model. All power supply modules (except the blank covers) have internal fans. All switches ship with a blank cover in the second power supply slot if switches are configured with only one power supply.

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, or with either a power supply or a blank cover.

The 250-W and 640-W AC power supply modules are autoranging units that support input voltages between 100 and 240 VAC. The 1025-W power supply module is an autoranging unit that supports input voltages between 115 and 240 VAC. The 640-W DC power supply module supports input voltages between -40 and -60 VDC.

Note For information on 250-W AC power supply support on the PoE-capable switch models, refer to the Release Notes for the Cisco Catalyst 3650 Switch on Cisco.com.

Each AC power supply module has a power cord for connection to an AC power outlet. The 1025-W and 640-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 1-10, Table 1-11, and Table 1-12show the PoE available and PoE requirements for Catalyst 3650 switches.
