Controller Overview With the Cisco Windows USB Console Driver, you can plug and unplugg the USB cable from the console port without affecting Windows HyperTerminal operations. Mac OS X or Linux require no special drivers. Only one console port can be active at a time. When a cable is plugged into the USB console port the RJ-45 port becomes inactive. Conversely, when the USB cable is removed from the USB port, the RJ-45 port becomes active. Note Four-pin mini Type B connectors are easily confused with 5-pin mini Type B connectors. They are not compatible. Only the 5-pin mini Type B can be used. USB Console OS Compatibility • Microsoft Windows 2000, XP, Vista • Apple Mac OS X 10.5.2 • Linux Figure 2 shows the back panel with a power supply, a blank power supply cover, and a fan tray.

You can use the LED indications to quickly assess the unit's status. The LED indicators are described in Table 1.
