■The Switch 8807 chassis provides seven slots in its board area: The top two accommodate fabrics, which can operate in 1+1 redundancy mode; the remaining five accommodate I/O or application modules, which you can select from various available models. All modules in this area are hot-swappable.

■At the bottom of the chassis is the power area that can accommodate one PoE entry module and two PSUs. The two PSUs are online-swappable; they can operate in 1+1 redundancy mode. The switch supports AC power inputs.

■On the right of the chassis is the fan area that contains one vertical hot-swappable fan tray. The fan tray draws and exhausts air from left to right.
