The Molex Tab

The Molex tab allows you to run an x4 backplane loopback test through the Molex

connector. Figure 6–8 shows the Molex tab.

1 No loopback board is provided. A loopback backplane can be purchased from Molex.

The following sections describe the controls on the Molex tab.

Status

The Status control displays the following status information during the loopback test:

■ PLL lock—Shows the PLL locked or unlocked state.

■ Channel lock—Shows the channel locked or unlocked state. When locked, all

lanes are word aligned and channel bonded.

■ Pattern sync—Shows the pattern synced or not synced state. The pattern is

considered synced when the start of the data sequence is detected.
