ATM 1-Port 622 Mb/s SMF Line Card DAGGL-CB

This document serves as a critical guide for the ATM 1-Port 622 Mb/s Single-Mode Fiber (SMF) Line Card (DAGGL-CB), which performs ATM cell-forwarding functions over an OC-12 (622 Mb/s) link. It specifies that the card requires GIGAswitch/ATM firmware V2.0 (and specific CMM versions depending on the system) and outlines compatible SMF cable specifications (EIA/TIA 492-CAAA, 9/125 µm, SC connector, up to 40 km, 0-13 dB loss).

The document extensively details how to test the line card using its various Light-Emitting Diodes (LEDs)—Module, Link, Information, Physical Layer (PHY), and FRU/Mode—providing comprehensive tables for interpreting their conditions during system initialization, firmware loading, self-tests, link status, and diagnostic error reporting. Simple loopback tests are also described for basic connectivity verification.

Furthermore, it provides essential instructions for installing and removing the DC-to-DC power module, noting that the correct module (DAGPL-AB 48V for 14-slot systems or DAGPL-AA 5V for 5-slot systems) is critical for the line card's operation. For general line card installation and removal, it refers to the system's Installation and Service manual.
