The EOS-4000 comes equipped with hot swappable power supplies, fans and port cards to allow users to quickly replace parts without affecting system investigate performance. A CompactFlash module acts as the unit’s disk drive for the controller’s CPU and is capable of being swapped out as well. The EOS-4000’s controlling software and non-volatile configuration data resides on the module.

Capabilities
EOS Xchange configuration commands are sent via a 10/100 Ethernet connection using a simple intuitive command set. With regard to network testing, some of the most significant capabilities are:

Automatic and Remote Reconfiguration and Fault Emulation
Quickly establish links, emulate optical power break with and without path failures, make topology changes, and re-route point-to-point, loop, or multicast connections.

Dynamic Device Testing
Through out-of-band control the switch can simulate faults; also, the capability exists to identify improperly operating devices.

Increased Resource Sharing Capabilities
Switched connectivity between local or remote—up to 50 km—facilities and between devices allows testing without physically moving equipment.

Cable and Hardware Diagnostics
Quickly isolate interconnect problems; investigate whether the network can provide reliable data transfer over specified distances without touching cables; and test hardware configurations such as hubs.
