Maintaining the MX2020 Fan Trays
date_range
09-Mar-21
Action
Monitor the status of the fans. The fan trays each contain multiple fans that work in unison to cool the router components. If one fan fails, the host subsystem adjusts the speed of the remaining fans to maintain proper cooling. A red alarm is triggered when a fan fails, and a yellow alarm is triggered when a fan tray is removed. During normal operation, the fans in each fan tray function at normal speed.
To display the status of the cooling system, issue the
show chassis environmentcommand,show chassis environment monitoredcommand,show chassis temperature-thresholdscommand, orshow chassis fancommand.For the fan trays, the output for the
show chassis environmentcommand is similar to the following:content_copy zoom_out_mapuser@host> show chassis environment Class Item Status Measurement Temp PSM 0 Absent PSM 1 Absent PSM 2 Absent PSM 3
