Viewing optical transceiver thresholds
The thresholds that determine the alarm status values for an optical transceiver are set by the
manufacturer of the XFP or SFP. To view the thresholds for a qualified optical transceiver in a
particular port, use the show optic threshold command as shown below.
Syntax: show optic threshold <port>
Specify the <port> variable in the following formats:
• PowerConnect B-Series FCX stackable switches – <stack-unit/slotnum/portnum>
For Temperature, Supply Voltage, TX Bias, TX Power, and RX Power, values are displayed for each of
the following four alarm and warning settings: High alarm, Low alarm, High warning, and Low
warning. The hexadecimal values are the manufacturer internal calibrations, as defined in the
SFF-8472 standard. The other values indicate at what level (above the high setting or below the
low setting) the system should send a warning message or an alarm. Note that these values are
set by the manufacturer of the optical transceiver, and cannot be configured.
Syslog messages
The system generates Syslog messages for optical transceivers in the following circumstances:
• The temperature, supply voltage, TX Bias, TX power, or TX power value goes above or below the
high or low warning or alarm threshold set by the manufacturer.
• The optical transceiver does not support digital optical monitoring.
• The optical transceiver is not qualified, and therefore not supported by Dell.
For details about the above Syslog messages, refer to Chapter 41, “Using Syslog”.
