Power Supply Considerations

The Cisco 170 series hardware operates on AC power and supports the ability to restore the previous power state of the system in the event that AC power is lost. Be aware of the following when interacting with system hardware:

The Cisco 170 series appliance requires 50 seconds from the time that AC power is applied before the power state can be updated and stored. This means that any changes to the power state within the first 50 seconds of applying AC power will not be observed if AC power is removed within that time.

The Cisco 170 series appliance requires 10 seconds from the time it is placed into standby mode before the power state can be updated and stored. This means any changes to the power state within the first 10 seconds of entering standby mode (including the standby mode itself) will not be observed if AC power is removed within that time.

Observe the following considerations:

Check the power at the site before installing the appliance 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.

The Cisco 170 series appliance does not have a user-selectable operating range. Refer to the label on the appliance for the correct AC-input power requirement.

Several styles of AC-input power supply cords are available; make sure that you have the correct style for your site.

Install an uninterruptible power source for your site, if possible.

You also need to provide power to the switch with the appropriate AC power cord for your location. Table 2-1lists the power cords that are used with the AC power supply.
