Figure 1-6 S9505 slots
All modules in the cabinet are hot-swappable.
z
The S9505 chassis provides seven slots: The top two accommodate SRPU
modules, which are in 1+1 redundancy; the remaining five accommodate LPU
modules and service processor cards, which can be hybrid.
z
At the bottom of the chassis is the power supply area that contains one PoE entry
area, two power supply units (PSU) that are online-swappable (which means you
can use one PSU to supply power to the whole switch while changing the other
PSU). The switch can be either AC-powered or DC-powered.
z
On the right of the chassis is the fan area that contains only one vertical fan tray.
The fan tray draws air from the left and exhausts on the right.
Note:
The two PSUs are online-swappable. But before removing or inserting a PSU, you must
first power off the PSU.
