ATM 4-Port Modular Line Card DAGGL–BA

This document provides critical information for using the ATM 4-Port Modular Line Card (DAGGL-BA), a logic module designed for ATM cell-forwarding. It supports various ATM modular PHY (modPHY) cards, including STS-3c (155 Mb/s) for multimode, single-mode fiber, and unshielded/screened twisted-pair, as well as T3 (44 Mb/s) and E3 (34 Mb/s) coaxial, and E1 (2 Mb/s) UTP.

The line card requires specific firmware versions (V2.0 for the line card and V1.74 for CMM). The document refers to the system's Installation and Service manual for general line card installation and removal. A significant portion details how to interpret the module's LEDs (Module LED, Link LEDs, and PHY LEDs) to understand the status of self-tests, firmware loading progress, and diagnostic messages.

Additionally, it provides installation instructions for optional components: the Cell Buffer Expansion Card (DAGCB-AA), Expanded Memory (SODIMM) options (8 MB or 16 MB), and DC-to-DC Power Modules (48V DAGPL-AB or 5V DAGPL-AA, depending on the GIGAswitch/ATM system). It emphasizes the importance of reading this document alongside system documentation before installation and use.
