Product Overview
Power Connectors
You can configure the speed and duplex settings consistent with the selected media type. For information on configuring
interfaces, see the switch software configuration guide.
Management Ports
You can connect the switch to a PC running Microsoft Windows or to a terminal server through either the RJ-45 console
port or the USB mini-Type B console port, also referred to as the USB-mini console port. These ports use the following
connectors:
RJ-45 console port uses an RJ-45-to-DB-9 female cable.
USB-mini console port (5-pin connector) uses a USB Type A-to-5-pin mini-Type B cable.
The USB-mini console interface speeds are the same as the RJ-45 console interface speeds.
To use the USB-mini console port, you must install the Cisco Windows USB device driver on the device that is connected
to the USB-mini console port and that is running Microsoft Windows.
Note:
For information about downloading the Cisco USB device driver, see
2000, Vista, 7, 8, and 10 USB Device Driver, page
With the Cisco Windows USB device driver, connecting and disconnecting the USB cable from the console port does not
affect Windows HyperTerminal operations. Mac OS X or Linux require no special drivers.
Note:
The 5-pin mini-Type B connectors resemble the 4-pin mini-Type B connectors, but they are not compatible. Use
only the 5-pin mini-Type B. See
Figure 2
USB Mini-Type B Port
The configurable inactivity timeout reactivates the RJ-45 console port if the USB-mini console port is activated, but no
input activity occurs for a specified time period. When the USB-mini console port deactivates due to a timeout, you can
restore its operation by disconnecting and reconnecting the USB cable. For information on using the CLI to configure the
USB-mini console interface, see the switch software guide.
Power Connectors
DC Power Connector
You connect the DC power to the switch through the front panel connectors. The switch has a dual-feed DC power
supply; two connectors provide primary and secondary DC power (DC-A and DC-B). The DC power connectors are near
the top right of the front panel. See
The switch power connectors are attached to the switch chassis. Each power connector has screw terminals for
terminating the DC power. All connectors are attached to the switch front panel with the provided captive screws.
The power connector labeling is on the panel. The positive DC power connection is labeled "+", and the return
connection is labeled "–".
The switch can operate with a single power source or with dual power sources. When both power sources are
operational, the switch draws power from the DC source with the higher voltage. If one of the two power sources fail,
the other continues to power the switch.
