Fan and communications module

- A removable unit that contains the power

supply cooling fans, an indicator light, and Ethernet ports.

Fibre Channel connections

When fully configured, the back of the FAStT900 Storage Server can accommodate
up to four host-side and four drive-side mini hubs. Each mini hub is a single,
removable unit that provides the Fibre Channel interface between a FAStT900
Storage Server, host computers, and drives. Each mini hub has two SFP module
ports. An SFP module is inserted into a mini-hub port. Figure 5 shows the Fibre
Channel components.
