158 33 rd ANNUAL REPORT 2020-21 connectivity in the housing colony. In this project, we provided LAN connectivity to Type - 4D Quarters (Akashganga 14 - 25), Takshashila Flatlets (T13 -T24), and Chittaranjan (C1 - C5). IUCAAhas two independent data centres, both of which host very critical services. Power supply to these data centres is routed through UPS to provide uninterrupted services. For one of the data centres, we have a 280 KVAABB UPS, whereas for the other, we have a 120 KVA Vertiv UPS. Batteries of these UPS were about four years old. Hence, we have replaced batteries of both the UPS systems. The existing all in one desktops used by the system administrator teamwere about 8 years old, and were out of warranty. It was very difficult to test latest version of software/packages on these systems. Hence, the replacement of old all in one desktops with newones is in progress. Due to pandemic situation, to conduct live lectures using zoom and Google classroom, a Video Conferencing System has been procured and installed. In addition, laptops have also been provided to the students to help to attend the lectures. We have installed closed-circuit television cameras (CCTV) to enable surveillance on computer hardware, data centre NON-IT equipment, and for security. Currently, the Library open office, TV room (allocated for visitors), Computer Centre Corridor, New Data Centre Corridor and BMS terrace area are under CCTVsurveillance In order to facilitate work from home, to increase the WiFi coverage and to improve the stability of connectivity in IUCAA premises, we have installed ruckus R720 (7), ruckus H320 (10) indoor wireless access point, and ruckus T610 (7) outdoor wireless access point and also relocated existing access points for better coverage.
