500 Series Stackable Managed Switches 7
phones, IP cameras, and wireless access points. The PoE
switches can detect and supply power to pre-standard
legacy PoE Powered Devices. Due to the support of legacy
PoE, it is possible that a PoE switch acting as a PSE may
mistakenly detect and supply power to an attaching PSE,
including other PoE switches, as a legacy PD.
Even though PoE switches are PSE, and as such should be
powered by AC, they could be powered up as a legacy PD
by another PSE due to false detection. When this happens,
the PoE switch may not operate properly and may not be
able to properly supply power to its attaching PDs.
To prevent false detection, you should disable PoE on the
ports on the PoE switches that are used to connect to PSEs.
You should also first power up a PSE device before
connecting it to a PoE switch. When a device is being falsely
detected as a PD, you should disconnect the device from the
PoE port and power recycle the device with AC power
before reconnecting its PoE ports.
Configuring the 500 Series Stackable
Managed Switch
Before You Begin
Verify the managing computer requirements in the product release notes.
The switch can be accessed and managed by two different methods; over
your IP network using the web-based interface, or by the Command Line
Interface (CLI) through the console port. Using the console port requires
advanced user skills.
Accessing and Managing Your Switch
Use the Web-Based Interface
To access the switch by using the web-based interface, you must know
the IP address the switch is using. The switch uses the factory default IP
address of 192.168.1.254 by default.
