Руководство По Установке для Cisco Cisco D9804 Multiple Transport Receiver

 

18 

78-4042990-01 Rev B 

The receiver is supplied with two power supplies that provide redundant power 
with no single point of failure. Operation requires both supplies to be powered up 
and switched on. Each power supply should be powered from a separate mains 
branch circuit, in order to ensure redundancy. 

The DC outputs from both power supplies are combined together in a current-
sharing scheme so that the total load is shared. 

 

To operate the MTR, you must connect it to an AC power source. For information 
about connecting the chassis to AC power, see Appendix B - Technical Specifications 
(on page 163). 

As Cisco units are designed for continuous operation, some products do not have a 
power switch. In this case the mains cord and/or DC power supply cable serve(s) as 
the mains disconnect device. 

 

WARNING: 

Make sure that at least one end of the power cable(s) remains 
easily accessible for unplugging, if you need to switch off the unit. 
For example: Ensure that the socket outlet is installed near the 
product. 

 

 

WARNING: 

To avoid electrical shock, connect the three-prong plug on this 
product to an earth-grounded three-pin socket outlet only.
