PLR615X Self-Test Mode
The PLR self-test mode is used to test internal systems and I/O ports. While in self-test
mode, the PLR tests for correct operation and shows a pass/fail status on the four status
LEDs as described in PLR615X Status LEDs (p.31) .
If any failures are detected, error codes are displayed to define the source of the failure.
The self-test connections are shown in Figure 33 .

To put the PLR615X into self-test mode, follow these steps:
1. Loop the SATA cable from Port A to Port B on the ProLink5 jacks.
2. Connect a coax cable from coax Channel 0 to coax Channel 3 and a second cable
from coax Channel 1 to coax Channel 2.
3. Disconnect the power and then reconnect the power.
During the self-test, the HB LED toggles once per second. The four status LEDs light up for
three seconds before initiating a repeating test-in-progress pattern. This alternating chase
pattern may take up to 60 seconds to run. Refer to Figure 34 .
