Chapter 3 Removing and Installing the PA-POS-1OC3

Replacing the SFP Optics Module

Step 3 Verify that the SFP optics module is functioning, by checking that the LINK LED is green.

Note The green (LINK) LED is turned on only if the cable is connected and the link is up. The orange

(ALARM) LED is turned on by the software if there are SONET alarms on the interface.

Step 4 Verify that the cabling is correct—single-mode to single-mode or multimode to multimode.

Note If the wavelength of the SFP optics modules are matched, but different modes are used (multimode to

single-mode or vise versa), the SFP optics module functions but not reliably.
