If single wavelength optics are fitted to the 2.5 Gb/s - 52 Mb/s Optical Out
port then the Self Test should be performed twice to verify all the Optical In
ports. Perform the test with the 2.5 Gb/s-52 Mb/s Optical Out port
connected to the 2.5 Gb/s Optical In port and repeat with the
2.5 Gb/s-52 Mb/s Optical Out port connected to the 662-52 Mb/s Optical
In port. Select the cable configuration from the test menu as appropriate.
