The following sections describe the controls on the HSMB/FMC 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.
