Chapter 1 Product Overview

Cisco MDS 9100 Series Ports

Caution The Cisco MDS 9000 Family has internal temperature sensors that are capable of shutting down the system if the temperature at different points within the chassis exceed certain safety thresholds. To be effective, the temperature sensors require the presence of airflow; therefore, in the event a fan module is removed from the chassis, the Cisco MDS 9140 Switch and the Cisco 9120 Switch will shut down after five minutes to prevent potentially undetectable overheating. However, the switches will shut down sooner if the higher-level temperature threshold is exceeded. For normal operation, the Cisco MDS 9124 Switch requires four fans. When fewer than four fans are operating on the Cisco MDS 9124 Switch, the switch will shut down.

Except for the Cisco MDS 9134 Switch, the fan modules each have one Status LED. The

Cisco MDS 9134 Switch fan modules do not have a Status LED. Fan module status is also indicated on a front panel LED.

Procedures for replacing and installing the fan modules are available in the “Removing and Installing Components” section on page 2-26.

On-Demand Port Activation Licensing allows expansion to 32 ports, with additional ports available as an 8-port group. The Cisco MDS 9134 Switch also offers two 10-Gbps ports. Table 1-1shows the mapping of ports to port groups.
