Chapter 1 Product Overview

Chassis

Airflow System

The airflow system includes an air intake at the bottom front side of the chassis and a fan module with two fans at the rear of the chassis. Two redundant power supplies power the fan module. The chassis internal air temperature controls the rotational speed of the fans.

The state of the fan module can either be observed through the NEMI-master or it can be read off the fan LEDs at the front side of the chassis. A green light indicates that everything is in working order. A red light signals that either a fan or a fan power supply is not working properly, which does not necessarily endanger the functioning of the air flow system because there are backup fans and fan power supplies. Refer to the Cisco Metro 1500 Series Software Configuration Guide for more information about fan observation using the NEMI-master. The ocmstate-f provides information on the fans.

You can check the fan module status on the display panel at the front of the chassis and through the NEMI. For more information about using the NEMI to check the fan status, refer to the Cisco Metro 1500 Series Software Configuration Guide.

Caution The fan system can only be replaced by Cisco-trained and -certified technicians.

Power Supply Module

The Cisco Metro 1500 series system provides high reliability in data and telecommunication applications because it has two identical, fully redundant power supplies. Each power supply can take over the power needs of the entire system. These power supplies provide 5V at 30A to the system, and full input-to-output, input-to-case, and output-to-output isolation. For detailed information on the power supply and how to replace it, see the “Determining Power Supply Status” section on page 3-23.

The state of the PSMs can either be observed through the NEMI-Master or it can be read off the LEDs at the front side of the frame. If both PSMs are working the green or red power LED is lit, otherwise there is no light at all.
