The S9505 chassis provides seven slots in its board area: The top two
accommodate SRPUs, which can operate in 1+1 redundancy mode; the remaining
five accommodate LPUs/service boards.
At the bottom of the chassis is the power area that contains one PoE entry module
and two PSUs. The two PSUs arehot-swappable; they can operate in 1+1

select AC or DC PSUs as needed.
On the right of the chassis is the fan area that contains one vertical fan tray. The
fans draw air in from the left and exhausts air from the right.
