Release Notes for Cisco Metro 1500 Series

These release notes describe last minute changes or additions to 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 "Cisco Connection Online" section.

New and Changed Information

The following sections provide new and changed information regarding the operation of the
Cisco Metro 1500 series system.

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.

Changes to the Operations Guide

The following changes to the chassis and the wavelength channel module (WCM) specifications affect the Cisco Metro 1500 Series Operations Guide.

Updated Rear View of the Chassis

On page 2-9 and page 4-20, the rear-view illustration of the chassis have been updated to reflect a design change. Figure 1 shows an updated rear view of the chassis.

Updated WCM Specifications

The following changes affect Chapter 9 of the Cisco Metro 1500 Series Operations Guide:

•

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.

•

In Table 9-2 and Table 9-3, the data rate range should be 10 to 200 Mbps and not 100 to 200 Mbps.

New High-Speed 850-nm Multiclock WCM

A new wavelength channel module is now available. This WCM operates with a transmitter wavelength of 830-nm to 860-nm. Table 1 describes the specifications of the High-Speed 850-nm multiclock WCM:

Caveats

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. As a workaround, wait for some time until the SNMP daemon polls all the entries. (CSCdr00712)
