downlink ports. The switch can source PoE power of up to 30W per port, with a total budget of 240W for the
entire switch.
The UPOE ports provide support for Cisco UPOE and each port can deliver a power of up to 60W, with a
total budget of 480W for the entire switch.
The PoE and UPOE ports use RJ-45 connectors with Ethernet pinouts. Luminaries are connected to PoE and
UPOE switches using CAT5/CAT6 cables and they are controlled through IP.
Gigabit Uplink Ports
The copper gigabit uplink ports support speed up to 1000Mbps.
Console Ports
The console ports connect the switch to a PC running Microsoft Windows or to a terminal server.
• RJ-45 console port (EIA/TIA-232). The RJ-45 console port connection uses an RJ-45-to-DB-9 female
cable.
• USB micro-Type B console port (5-pin connector).
If you use the USB micro-Type B console port, the Cisco Windows USB device driver must be installed on
any PC connected to the console port (for operation with Microsoft Windows). Mac OS X or Linux do not
require special drivers.
This illustration shows a 5-pin micro-Type B USB port.

With the Cisco Windows USB device driver, you can connect and disconnect the USB cable from the console
port without affecting Windows HyperTerminal operations.
The console output always goes to both the RJ-45 and the USB console connectors, but the console input is
active on only one of the console connectors at any one time. The USB console takes precedence over the
RJ-45 console. When a cable is connected into the USB console port, the RJ-45 console port becomes inactive.
Conversely, when the USB cable is disconnected from the USB console port, the RJ-45 port becomes active.
You can use the command-line interface (CLI) to configure an inactivity timeout which reactivates the RJ-45
console if the USB console has been activated and no input activity has occurred on the USB console for a
specified time.
