Cisco Systems ASR 9014CFD Environmental Monitoring Temperature Sensor, System Specifications

Chapter 1 Introduction

Environmental Monitoring Temperature Sensor

Environmental Monitoring Temperature Sensor

The Cisco ASR 901 router has a temperature sensor to detect overtemperature conditions inside the chassis. The overtemperature detection trips at 70°C. This condition is reported to the processor as an interrupt, where the software generates the appropriate alarms. If the router reaches a temperature of 85°C, the power supply cycles itself to prevent the router from exceeding the maximum temperature while being powered up.

Table 1-3lists the system specifications for the Cisco ASR 901 router.

Router Interface Numbering

Each network interface on a Cisco ASR 901 router is identified by a slot number and a port number, explained in this sequence:

•Logical slot numbers starts from 0 for all built-in interfaces. The numbering format is Interface type Slot number/Interface number. Interface (port) numbers begin at logical 0 for each interface type.

•Logical interface numbering for T1/E1 ports on the TDM interface module runs from 0/0 through 0/15. Ports are numbered bottom to top, left to right.

•Logical interface numbering for the built-in ethernet ports runs from g0/0 through g0/3, the combo ports run from g0/4 to g0/7 and the SFP ports run from g0/8 through g0/11. The GE ports are numbered bottom to top, left to right.
