Chapter 4 Installing the ASA 5505
PoE Ports and Devices
On the 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
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
ASA 5505 does not recognize that a PoE device is attached. In this case,
power is not provided to the port.
PoE Ports and Devices
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.
• Cisco IP Phone 7970 is always in low-power mode when drawing power from
the ASA 5505.
Installing the Chassis
To install the ASA 5505, perform the following steps:
Step 1 Place the chassis on a flat, stable surface. The chassis is not rack mountable.
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.

Connecting to Network Interfaces
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.)

Powering on the ASA 5505
To power on the 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.
