Per-port MDI or MDIX on RJ-45 the copper daughter board has MDI-MDIX Auto-crossover on all the RJ-
45 ports and eliminate the use of cross-over cable between the devices. Also port specific user settings
(such as FDX or HDX, copper 10/100 speed) can be fixed using software commands. Alarm Contact
Optional) Alarm Contact option is offered as a configuration option. The two alarm contacts are SPST NC
Form-C relays, and an open condition indicates abnormal status. The Hardware Alarm monitors internal
power on the main board, and the Software Alarm is activated by one or more user-selected software
traps.
