This check will monitor the *electrical power* and the *state* of Extreme Networks Power Supply Inputs. It is an **enhanced replacement** for the original Checkmk check *netextreme_psu_in*. > This plugin requires at least Extreme Networks' firmware version 30.x. It has not been tested with earlier versions. > This plugin adds the new "Extreme Power Supply Input" rule. After installation, the old rules named "Parameters for input phases of UPSs and PDUs" will no longer be effective. You must manually migrate them to the new "Extreme Power Supply Input" rule set. ### Improvements over the original check * More detailed state handling: instead of only ‘OK’ or ‘not detected’, this check distinguishes between Powered On, Powered Off, and Failed. * Flexible configuration: * "Powered Off" and "Failed" can be mapped to the desired Checkmk states (default: `CRIT`). * Upper power consumption thresholds can be adjusted in WATO.

This check will monitor the *rx_signal_power* and the *tx_signal_power* of Extreme Networks optical modules (SFP). > This plugin requires at least Extreme Networks' firmware version 30.x. It has not been tested with earlier versions. > There is currently a bug in Extreme Networks' firmware. The "etsysEntitySfpSensorState" returns a value of 6 (highAlarm) instead of 4 (normal). This error only occurs in SNMP queries and not in the CLI. To resolve the issue, you need at least firmware version v31.7.1.4-patch1-77 or v32.3.x.
