1.5.6 Fan Tray

The fan tray is located on the right side of the S7500 series. The fan tray is directly
connected to the backplane through a connector. All fan fault signals flow to the
backplane and then the backplane sends them to the SRPU for processing. The fan
tray is hot swappable.
Fan trays of the S7506R, S7503, and S7506 are slightly different. Fan trays of the
S7506R and S7503 are fixed by screws, while the fan tray of the S7506 is fixed by two
locks.
