Preface
The quad serial PMC provides connectivity over the WAN. The quad serial
interface supports four full-duplex synchronous (HDLC), asynchronous, and
bisynchronous serial ports.
In this guide, the Passport* 5430 Multiservice Access Switch is referred to as the
Passport 5430.
Before You Begin
This guide is intended for qualified service personnel who are installing the
Passport 5430 for the first time or who need to install or replace any Passport 5430
customer-replaceable unit (CRU). A qualified service person should have
appropriate technical training and experience and be aware of the hazards
involved in installing and replacing CRUs.
Before installing the quad serial PMC module into the Passport 5430, make sure
that all network wiring has been installed on the premises using standard
cable-system practices.
Before turning on the Passport 5430 for the first time, contact your network
administrator to determine which software configuration option to use.
Note: The Passport 5430 Quad Serial PMC Module can be installed only on
the expansion card (Part No. DU0004001).
