The HSMA Tab
The HSMA tab ( Figure 6–5 ) allows you to perform loopback tests on the transceiver
(XCVR) and CMOS ports .

You must have the loopback HSMA installed on the HSMC Port A connector that you
are testing for this test to work correctly.
The following sections describe the controls on the HSMA 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.
