![]() Hence, air filters of routers should be cleaned every month by BSNL.Ģ MPBN DOS AND DONTS 2 (7) MPBN Equipment Monitoring: Equipment Temperature: Temperature of the equipment should be maintained as per the recommended values below: Recommended Values (in degree Node Celsius) Switch Router 0-60 The command for taking the temperature for every slot of router >show hardware detail The command for taking the temperature for every slot of switch >show temperature Laser Power Levels on router STM-1/POS Ports: The Rx power level at STM-1/POS ports should be in the optimal range as specified below: Rx voltage level (in dbm) Sensitivity 2 Optimal 12 1 Range Higher Rx Power can be dangerous for the cards which can lead to failure of ports on the card while lower Rx Power levels can lead to fluctuation of the card ports and may result in link fluctuation and hence result in losses.ģ MPBN DOS AND DONTS (7) Router Performance Monitoring: The routers need to be monitored for CPU and Memory Utilization: Monitoring should be done on regular basis to see that CPU utilization is below 60%. These air filters if blocked would result in: Router cards not getting detected Temperature of the router slots would increase The effect of blockage is that the routers will start malfunctioning. Air Filter: Every Router has got air filters to maintain airflow. Ambient Room Temperature: Ambient temperature should be maintained at degree Celsius at optimal distance from routers (4-5 feet distant from the router hardware). The importance of the statement is underscored by the fact that the MPBN components get impacted by the dust leading to degradation of performance. Environmental Requirements: Dust Free: The switch room should be clean and dust free. The document is the outcome from the MPBN audit carried out recently in one of the circles in the BSNL Network. This document needs to be read together with the MPBN O&M document which is attached with this document. 1 MPBN DOS AND DONTS 1 (7) Mobile Packet Backbone Network (MPBN) Do s and Don ts This document describes the various aspects to be undertaken for the MPBN maintenance on a high level. ![]()
