FDDI Dual-Attached Intelligent Module User’s Guide Page 1-3

an external Optical Bypass Switch (OBS) that allows full FDDI operation

to continue if the ATX is disabled.

Both FDDI standard station management (SMT) and SNMP are

supported, allowing you to use a variety of network management software

to conﬁgure your 3F00-01/3F55-01 and monitor your network.

Both the 3F00-01 and 3F55-01 are protected by a built-in temperature

sensor that sends an alarm if the module overheats. Local and remote

loopback tests on the module, and front panel LEDs showing the ring

status, aid in troubleshooting and diagnostics.

1.2 STANDARDS

The 3F00-01 and 3F55-01 comply with the following standards:

• ANSI X3T9.5 (PMD, PHY, MAC, and SMT)

• IEEE 802.1d and 802.1i

1.3 CONNECTORS

The 3F00-01 and 3F55-01 each have three connectors that are shown in

Figure 1-2 and Figure 1-3:

• Two Media Interface Connector (MIC) receptacles – an A port and a

B port.

• One RJ-11 modular jack, for connecting an optional Optical Bypass

Switch (OBS). (The OBS is not supplied with the 3F00-01 or the

3F55-01.)
