Diagnosing and correcting PoE problems

This section discusses some common problems in using the PoE features of the Ethernet Routing Switch 2500-PWR. This section discusses the following topics:

•"Status codes on PoE ports" (page 158)

Status codes on PoE ports

You may see an error displayed for a port running PoE. If these errors appear, they are in the port status section of the PoE displays in the CLI and the web-based management system. The following are the messages that display and their explanations:

•Detecting—port detecting IP device requesting power

•Delivering power—port delivering requested power to device

•Disabled—port power state disabled

•Invalid PD—port detecting device that is not valid to request power

•Deny low priority—power disabled from port because of port setting and demands on power budget

•Overload—power disabled from port because port is overloaded

•Test—port in testing mode, which is set using SNMP

•Error—an unspecified error condition

Configuring PoE switch parameters using the CLI

You configure power parameters for each Ethernet Routing Switch 2500-PWR using the CLI. You can configure the DC power source, the power pairs, and the power usage with this management system. This section contains information about the following topics:

•"poe poe-pd-detect-type command" (page 158)

•"poe poe-power-usage-threshold command" (page 159)

•"poe poe-trap command" (page 160)

•"no poe-trap command" (page 160)

poe poe-pd-detect-type command

The poe poe-pd-detect-typecommand sets the method the Ethernet Routing Switch 2500-PWR uses to detect the power devices connected to the front ports. The syntax for the poe poe-pd-detect-typecommand is:
