The XCVR2 Tab
The XCVR2 tab allows you to perform loopback tests on the QSFP and HSMB
Transceivers, and HSMB Parallel interfaces. Figure 6–8 shows the XCVR2 tab.
1 You must have the loopback HSMC installed on the HSMC port B connector this test
to work correctly. Unless you have a QSFP loopback module, you will need test the
QSFP in the internal loopback mode (serial loopback = 1).
The following sections describe the controls on the XCVR2 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, and all TX and RX PLL lanes are
phase locked to data; RX lanes are word aligned and deskewed.
