Fan tray failure
The S6520X-SI switches (except the S6520X-26XC-UPWR-SI and S6520X-54XC-UPWR-SI) use
built-in fan trays. If a fan tray fails, contact H3C Support.
The S6520X-26XC-UPWR-SI and S6520X-54XC-UPWR-SI switches use removable fan trays. If an
LSPM1FANSB fan tray fails, the fan tray Alarm LED turns on and the switch sends alarm messages.
You can see "Installing and removing a fan tray" to re
place the fan tray.
