Chapter 2: Loop Configuration With the Fibre Channel Hub

Determining Hub Management

Follow these guidelines for planning hub management:

1.

Determine how the hub is to be managed:

•

locally: ANSI console terminal, or a PC with a serial port

If you use a PC, its serial port must support 9600 bps, 8 data bits, Xon/Xoff flow
control, no parity, and 1 stop bit.

For the connection between the hub and the console terminal or PC, use only
the serial cable and adapters included with the hub.

•

remotely: Internet browser, Telnet console, or SNMP MIB browser

You can use the 10-Base-T Ethernet port on the hub’s front panel for this
connection.

Obtain a unique IP address for the hub from the system administrator. For this,
you need the hub’s media access control (MAC) address, which is located on
the far left of the hub’s rear panel, as shown in Figure 2-8.

Figure 2-8

Hub MAC Address Location

For initial installation, it is recommended that the hub be on the same subnet as
the server or workstation you are using—the same subnet as the network to
which it will be initially connected.

2. Make sure you have the cabling required for the management option you select.
