3H08-04 FE Switch Module

1.4 3H08-04 FE SWITCH MODULE

The 3H08-04 (Figure 1-3) provides connection for four independent 100BASE-FX LANs to the ATX backplane and packet processing engine (PPE). It includes processing circuitry for receiving and forwarding packets between the connected 100BASE-FX LANs within each module. The 3H08-04 contains several LEDs to indicate the module’s operational status.

The 3H08-04 supports fiber optic and the IEEE 802.3 100BASE-FX specification.

1.4.1 Connectors

The 3H08-04 includes four pairs of fiber optic socket connectors for fiber optic cabling. Receive (RX) and transmit (TX) connectors are clearly marked on the front panel of the module. The ATX power supply provides the power for the module.

1.4.2 LEDs

The 3H08-04 contains a total of 14 green LEDs labeled LINK, RX, and TX for each segment, plus PROC and PWR for the module. The LEDs are described in Chapter 5 of this manual.

1.4.3 Offline Button

Use the offline button before swapping the module, to take it offline until the replacement is installed.
