PoE Ports and Devices
PoE Ports and Devices
On the Cisco ASA 5505, switch ports Ethernet 0/6 and Ethernet 0/7 support PoE
devices that are compliant with the IEEE 802.3af standard, such as IP phones and
wireless access points. If you install a non-PoE device or do not connect to these
switch ports, the adaptive security appliance does not supply power to the ports
and the device must be powered on its own.
These ports are the only ports that can provide power for IP phones or other PoE
devices. However, these ports are not restricted to that use. They can also be used
as Ethernet switch ports, like the Ethernet switch ports numbered 0 through 5. If
a PoE device is not attached, power is not supplied to the port.
When connecting PoE devices, use the following guidelines:
•Use straight-through cable only. Using crossover cable does not enable the
Cisco ASA 5505 to provide power to the PoE ports.
•Do not disable auto-negotiation (force speed and duplex) on E0/6 and E0/7
when using them to connect PoE devices. If auto-negotiation is disabled, the
Cisco ASA 5505 does not recognize that a PoE device is attached. In this
case, power is not provided to the port.
Note Be careful when connecting a Cisco PoE device to a non-PoE switch
port (E0/0 through E0/5). If auto-negotiation is disabled for that
switch port, a network loopback might occur with some Cisco
Powered Device (PD) models.
•The Cisco IP Phone 7970 is always in low-power mode when drawing power
from the Cisco ASA 5505.

Installing the Chassis
You can wall-mount or rack-mount the Cisco ASA 5505. The part number for
ordering a wall-mount kit for the Cisco ASA 5505 is ASA-5505-WALL-MNT= ,
the part number for ordering a rack-mount kit for the Cisco ASA 5505 is
ASA5505-RACK-MNT=. For information on wall-mounting or rack-mounting
the Cisco ASA 5505, see “Mounting the ASA 5505 Chassis” section in the
Cisco ASA 5500 Series Hardware Installation Guide.
To install the Cisco ASA 5505, perform the following steps:
Step 1 Place the chassis on a flat, stable surface.
Step 2 Connect Port 0 to the public network (that is, the Internet):
a. Use a yellow Ethernet cable to connect the device to a switch or hub.
b. Use one of the yellow Ethernet cables to connect the device to a
cable/DSL/ISDN modem.
Note By default, switch port 0 is the outside port.
Step 3 Connect your network devices with an Ethernet cable to one of the remaining
seven switched ports (numbered 1 through 7).
If you are connecting any Power over Ethernet (PoE) devices, connect them to one
of the switch ports that support PoE (ports numbered 6 and 7).
Connecting to Network Interfaces
To connect to a network interface, perform the following steps:
Step 1 Locate an RJ-45 to RJ-45 Ethernet cable.
Step 2 Connect one end of the Ethernet cable to an Ethernet port (ports 0 through 7), as
shown in Figure 4-2. (Typically Ethernet port 0 is used to connect to an Internet
router.)

Step 3 Connect the other end of the Ethernet cable to a device, such as a router, desktop
computer, or printer.
Note When connecting a computer to an inside port on the rear panel of the
adaptive security appliance, use a straight through cable because ports 0
through 5 are switched ports and ports 6 and 7 are PoE ports and both
require that you connect a straight through cable.

Powering on the Cisco ASA 5505
To power on the Cisco ASA 5505, perform the following steps:
Step 1 Connect the power supply with the power cable.
Step 2 Connect the small, rectangular connector of the power supply cable to the power
connector on the rear panel.
Step 3 Connect the AC power connector of the power supply input cable to an electrical
outlet.
Note The Cisco ASA 5505 does not have a power switch. Completing Step 3
powers on the device.
Step 4 Check the power LED; if it is solid green, then the device is powered on.
For more information, see the “Front Panel Components” section on page 4-10.
Setting Up a PC for System Administration
You can perform setup, configuration and management tasks from a PC using the
command-line interface or with the Adaptive Security Device Manager (ASDM)
application, which provides an intuitive graphical user interface (GUI).
In addition to configuration and management capability, ASDM also provides
configuration wizards for initial configuration, VPN configuration, and
high-availability configuration.
For more information about using ASDM for setup and configuration, see
Chapter 1, “Configuring the Adaptive Security Appliance.”
To set up a PC from which you can configure and manage the Cisco ASA 5505,
perform the following steps:
Step 1 Make sure that the speed of the PC interface to be connected to one of the Cisco
ASA 5505 inside ports is set to autonegotiate. This setting provides the best
performance.

Chapter 4 Installing the ASA 5505
Setting Up a PC for System Administration
By default, the Cisco ASA 5505 automatically negotiates the inside interface speed.
If autonegotiate is not an option for the PC interface, set the speed to either 10 or
100 Mbps half duplex. Do not set the interface to full duplex; this causes a duplex
mismatch that significantly impacts the total throughput capabilities of the interface.
Step 2 Configure the PC to use DHCP (to receive an IP address automatically from the
Cisco ASA 5505), which enables the PC to communicate with the Cisco ASA
5505 and the Internet as well as to run ASDM for configuration and management
tasks.
Alternatively, you can assign a static IP address to your PC by selecting an address
in the 192.168.1.0 subnet. (Valid addresses are 192.168.1.2 through
192.168.1.254, with a mask of 255.255.255.0 and default route of 192.168.1.1.)
When you connect other devices to any of the inside ports, make sure that they do
not have the same IP address.
Note The MGMT interface of the adaptive security appliance is assigned
192.168.1.1 by default, so this address is unavailable.
Step 3 Use an Ethernet cable to connect the PC to a switched inside port on the rear panel
of the Cisco ASA 5505 (one of the ports numbered 1 through 7).
Step 4 Check the LINK LED to verify that the PC has basic connectivity to the Cisco
ASA 5505.
When connectivity is established, the LINK LED on the front panel of the Cisco
ASA 5505 lights up solid green.
You can now access the ASDM and the ASDM Startup Wizard. See Chapter 1,
“Configuring the Adaptive Security Appliance” for information about how to
perform initial setup and configuration of the Cisco ASA 5505.

Installing a Cable Lock
The Cisco ASA 5505 includes a slot that accepts standard desktop cable locks to
provide physical security for small portable equipment, such as a laptop computer.
The cable lock is not included.
To install a cable lock, perform the following steps:
Step 1 Follow the directions from the manufacturer for attaching the other end of the
cable for securing the adaptive security appliance.
Step 2 Attach the cable lock to the lock slot on the back panel of the Cisco ASA 5505.

Front Panel Components
The LINK/ACT indicators on the front panel of the Cisco ASA 5505 are normally
solid green when a link is established and flashing green when there is network
activity. Each Ethernet interface (numbered 0 through 7) has two LEDs: one to
indicate the operating speed and the other to indicate whether the physical link is
established.
