64 CHAPTER 3: GETTING STARTED To set system clocks, follow these steps: 1 From the System Administration menu, select [4] Manage System Clock to display the System Clock Configuration menu, shown in Figure 34. Figure 34 System Clock Configuration Menu 2 Select [3] Set PriorityClock 1 to specify the clock which you want to designate as the priority 1 (highest priority) clock. 3 Enter the option number corresponding to the clock you want to designate as the priority 1 system clock. The clock options correspond to the available ports. If you are configuring a PathBuilder S310, do not select unavailable ports (ports 2-4, CBR ports 2 and 3, and OC3/STM-1) as system clocks-even though the software lists these ports and allows you to select them. 4 Repeat steps 2 and 3 to designate up to seven additional clocks as the priority 2 through 8 clocks, substituting the appropriate option in step 2. For example, to designate the priority 2 clock, select [4] Set PriorityClock 2. 5 Select [11] Set System Clock to Highest PriorityClock to set the system clock to the clock you designated as the priority 1 clock in step 3 above. If this clock fails, the PathBuilder S330/S310 will automatically use the clock with the next highest priority as its reference clock. Setting up Communication Parameters In order for the PathBuilder S330/S310 to communicate to the Ethernet network, you must set the correct communication parameters. To do this, select [3] Manage IP Network Configuration From the System Administration menu, to display the Manage IP Network Configuration menu, shown in Figure 35, and configure the following: n Local host IP address n Trap client n Default gateway The subsections following the figure describe how to set these parameters.
