Release Notes for the Cisco Metro 1500 Series

This document describes the caveats for the Cisco Metro 1500 series metropolitan area network (MAN) dense wavelength division multiplexing (DWDM) documentation set.

Note Although the software image in a new Cisco Metro 1500 series system operates correctly, later software images containing the latest upgrades and modifications are released regularly to provide you with the most optimized software available. We strongly recommend that you check for the latest released software images at the World Wide Web locations listed in the "World Wide Web" section.

Introduction

The Cisco Metro 1500 series system is a high-performance, wavelength division multiplexer that provides bidirectional data communication. It is designed for communication over optical links in which different devices or applications are communicating over multiple fibers. Using wavelength conversion, several devices can communicate while being connected over one duplex fiber or two single fibers.

The Cisco Metro 1500 series system expands the distance and application capabilities of existing local area networks (LANs), metropolitan area networks (MANs), and storage area networks (SANs). It is protocol-independent and can support virtually any fiber-optic device.

New and Changed Information

This section lists new features that appear in this release of the Cisco Metro 1500 series.


Feature	Description
TDM 4 X ESCON wavelength channel module (WCM)	A new high-performance WCM that uses TDM technology
High-speed 850-nm multiclock WCM	A new high-performance WCM that operates in the 850-nm transmission wavelength

Caveats

Symptom: If you hot swap the network element management interface (NEMI) module in a Cisco Metro 1500 series system, the metro1500PSTable entry in the SNMP table does not display "ON". This error is intermittent; it does not happen each time you hot swap a NEMI.

Restrictions

•

The Cisco Metro 1500 series system does not support the use of standard reach lasers. The specifications provided for the transmitter output power, link loss budget, and calculated link distance of the WCMs pertain only to the extended category and not to the standard category.

•

The TDM 4 x ESCON wavelength channel module does not support single mode fiber.

Default Password

The default password for the root, netadmin, ppp, and user accounts is ChgMeNOW. For security reasons, you should change all four account passwords as soon as possible. Log in as root and use the password command to change the passwords for all the accounts.

If you do not receive a password prompt, then an unsupported adapter is being used to connect to the
Cisco Metro 1500 serial port. Use only the DB-9 to RJ-45 adapter that shipped with the unit.
