PLR605X Self-Test Mode
The PLR self-test mode is a diagnostic mode used to test internal systems and I/O ports.
During self-test mode, the PLR tests for correct operation and shows a pass/fail status on
the 7-segment display. If any failures are detected, error codes are displayed to define
the source of the failure.
To put the PLR605X into self-test
mode, refer to Figure 29 and
follow these steps:
1. Loop the SATA cable from
Port A to Port B on the
ProLink5 jacks.
2. Loop the fiber cables from
Port A to Port B on the
ProLink6 jacks.
3. Disconnect the power and
then reconnect the power.
When the self-test is complete,
disconnect power, remove loopback connections, and restart power. Refer to Self-
Test Mode Messages (p.30) and the following table for more information on the error
messages.
Self-Test Mode Messages
During self-test mode, the PLR605X displays the messages listed in the following table
on the 7-segment display. If any E r r message is displayed, the PLR should be sent in for
repair. Daktronics field personnel may also reference the ProLink Router 605X (PLR605X)
Self-Test Manual (DD1750417) for further information concerning the PLR self-test.
