The current plan being considered is trenching for a new fiber plant in an alleyway that runs parallel to L street, which will connect with the 9th street fiber and end at the L street building. The SWAN project is targeted to start the construction phase in June 2001. The campus voice switch has battery backup, allowing it to remain in service for up to eight hours. The core data network equipment within the Telecommunications building has protected power and will remain in service for 40 minutes. During the 40 minute window, Facilities Services will activate a generator located at the Telecommunications building to extend power to the voice switch and the data network.
Refueling is required every four hours.
This generator will enable the data network and voice switch to remain operational, and will charge the voice system battery. The campus deployed UPS devices throughout the communications closets during the Network 21 installation. ADFs have four-hour capacity, BDFs two hours and IDFs 20 minutes. The 20-minute connectivity allows system administrators to gracefully secure servers in the event of a campus wide power failure. Research networks that run independently of the UCDNet campus backbone are the favored option to maintain service quality for the majority of campus users.
