3–2 DEChub 900 MultiSwitch Owner’s Manual
• Supports the setup port redirection for network module initialization.
• Supports out-of-band management (OBM) for the hub and network modules.
• Supports dynamic reconfiguration of network modules and module intercon-
nect for Ethernet, Token Ring, and FDDI across the DEChub 900 MultiSwitch
backplane.
Hub Manager Ports
The Hub Manager provides two external ports: the hub setup port and the hub out-of-
band management (OBM) port. Figure 3–1 illustrates the cabling for both the setup
port, and the OBM port.
Hub Setup Port
The signals on the hub setup port (8-pin MJ) conform to the signaling standard
EIA-232D. The port appears as a data terminal equipment (DTE) device. Devices
that use the standard EIA-423 signaling are compatible with the hub setup port.
The setup port can be connected to a terminal device or a personal computer using
various cables and adapters. Refer to Table 3–1 for your configuration.
Refer to Appendix B for information about signal connections. Refer to the Using the
Hub Setup Port section in this chapter for information about configuring the hub.
