Network Ports
Looking at the rear of the ASA, where the ports are located, port 1 is on the left, and port 8 is on the right,
next to the console and management ports. Each port is accompanied by a pair of LEDs, one each for link
status (L) and connection status (S). The ports are named and numbered Gigabit Ethernet 1/1 through Gigabit
Ethernet 1/8. The ports are named and numbered Gigabit Ethernet 1/1 through Gigabit Ethernet 1/4.
Console Ports
The ASA has two external console ports, a standard RJ-45 port and a Mini USB Type B serial port. 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. The console ports do not have any hardware flow control. You can use the command-line interface
(CLI) to configure your ASA through either serial console port by using a terminal server or a terminal
emulation program on a computer.

Note
Internal and External Flash Storage
The ASA contains one internal USB flash drive, and a standard USB Type A port that you can use to attach
an external device. The USB port can provide output power of 5 volts, up to a maximum of 500 mA (5 USB
power units).

Overview

The RJ-45 (8P8C) port supports RS-232 signaling to an internal UART controller. The RJ-45 console
port does not support a remote dial-in modem. You can use a standard management cable (Cisco part
number 72-3383-01) to convert the RJ45-to-DB9 connection if necessary.
The Mini USB Type B port lets you connect to a USB port on an external computer. For Linux and
Macintosh systems, no special driver is required. For Windows systems, you must download and install
a USB driver (available on software.cisco.com). You can plug and unplug the USB cable from the console
port without affecting Windows HyperTerminal operations. We recommend shielded USB cables with
properly terminated shields. Baud rates for the USB console port are 1200, 2400, 4800, 9600, 19200,
38400, 57600, and 115200 bps.
For Windows operating systems, you must install a Cisco Windows USB Console Driver on any PC connected
to the console port before using the USB console port. See
Windows
for information on installing the driver.
An embedded eUSB device is used as the internal flash; it is identified as disk0.
