.Connecting to Power (Power Supply) The chassis ships with only one power supply, and a second power supply option is at your discretion. When the chassis is equipped with two power supplies, you can have the following advanced performance. ♦ Hot Swappable - The design of the power system is based on an idea of providing maximum flexibility and redundancy. In this way, you may remove any of the two power supplies without turning off the system. ♦ Redundancy - During operation, both power supplies are switched on and share the current load. In case that one of them should fail, the other will instantaneously take 100% of the load without any loss. Similarly, if one power supply is removed from servicing, it can be switched off and removed while the chassis continues functioning. ♦ Protection System - The power of each converter bay comes from the two shared power supplies. Each bay is isolated from each other under a certain protection mechanism, so that it is free from any problem that might occur to the power supplies or faulty converter bay. This is the best solution to protect your investment in media converters. There is an optional solution for the backup power, Attentio4n8! volt DC to DC Power Supply. The chassis system is equipped with one power supply and allows one additional power supply for redundancy. For reliable operation, we suggest that you run the chassis system with two power supplies are in place. 10
