3.6.1 48 V DC Power Out Cables
The 48 V DC power cables are supplied by Snell and can be ordered as either 2.5 meter
cables or 8 meter cables.
• All of the 48 V DC cables from the power supply shelves to the Sirius 800 router
must be the same length to ensure that the voltage drop along each cable is the
same at high currents.
• The power supply shelves MUST be isolated from the AC supply by means of the
external distribution switch/circuit breaker before connecting or disconnecting the
48 V DC power cables.
The three 48 V DC power connectors on each power supply shelf are common. Any two of
the three sockets can be used to power the router frame.
