Sfp And Qsfp Module Slots; Management Ports - Cisco Catalyst C3850 Series Hardware Installation Manual

Product Overview
Depending on the installed power supply modules, each port can deliver up to 60 W of Cisco UPOE. See the
Power Supply Modules, on page 25
Cisco UPOE power per port. The output of the PoE+ circuit has been evaluated as a Limited Power Source
(LPS) per IEC 60950-1.
Note
Restrictions for the WS-C3850-12X48U-L, WS-C3850-12X48U-S and WS-C3850-12X48U-E switch models:
• A maximum of 28 ports are available for UPoE connections. This is because some power from the power

Management Ports

The management ports connect the switch to a PC running Microsoft Windows or to a terminal server.
• Ethernet management port. See
• RJ-45 console port (EIA/TIA-232). See
• USB mini-Type B console port (5-pin connector).
The 10/100/1000 Ethernet management port connection uses a standard RJ-45 crossover or straight-through
cable. The RJ-45 console port connection uses the supplied RJ-45-to-DB-9 female cable. The USB console
port connection uses a USB Type A to 5-pin mini-Type B cable. The USB console interface speeds are the
same as the RJ-45 console interface speeds.
