Chapter 2 Preparing for Installation General Site Requirements The following chassis models can have either an AC or DC power supply: Cisco ASA 5510, Cisco ASA 5520, Cisco ASA 5540, and Cisco ASA 5550. Observe the following considerations: • Check the power at the site before installing the chassis to ensure that the power is "clean" (free of spikes and noise). Install a power conditioner if necessary, to ensure proper voltages and power levels in the source voltage. • Install proper grounding for the site to avoid damage from lightning and power surges. • In a chassis equipped with an AC-input power supply, use the following guidelines: - The chassis does not have a user-selectable operating range. Refer to the label on the chassis for the correct AC-input power requirement. - Several styles of AC-input power supply cords are available; make sure you have the correct style for your site. - Install an uninterruptible power source for your site, if possible. - Install proper site grounding facilities to guard against damage from lightning or power surges. • In a chassis equipped with a DC-input power supply, use the following guidelines: - Each DC-input power supply requires dedicated 3-5 amp service. - For DC power cables, we recommend a minimum of 14 AWG wire cable. - The DC return connection to this system is to remain isolated from the system frame and chassis. You will also need to provide power to the switch with the appropriate AC power cord for your location. Table 2-1 lists the power cords that are used with the AC power supply.
