Power Supply Module Overview
The switch operates with either one or two active power supply modules. A Catalyst 3850 switch that is
part of a StackPower stack operates with power supplied by other stack switches.
You can use two AC modules, two DC modules, one AC and one DC module, or one module and a blank
cover.
All power supply modules have internal fans. All switches ship with a blank cover in the second power
supply slot.
Table 4-1 describes the supported internal power supply modules.
For information on available PoE, see these sections:
• Table 1-13 on page 1-19 (available PoE with AC power supply)
• Table 1-14 on page 1-19 (available PoE with DC power supply)
• Table 1-15 on page 1-19 (switch power supply requirements for PoE and PoE+, and Cisco UPOE)
