Carrier grade groomerII – installation guide
1.1.5 Power connections
The Carrier Grade GroomerII is supplied as either an AC or a DC powered system.
The system will auto adjust to the supplied voltage in AC and DC installations (115 or
230 VAC and -48VDC, see appendix D). Both power cords must be connected to
maintain the standard power module redundancy. The unit will show single PSU
operation via an indicator at the front. The internal power supply is rated at a
maximum of 600W, however the unit is designed to consume no more than 300W
during normal operation (see Appendix E).
Consideration should be given to the connection of the equipment to the supply circuit
and the effect that overloading of the circuits might have on overcurrent protection
and supply wiring. Appropriate consideration of equipment nameplate ratings should
be used when addressing this concern.
1.1.6 Earth connection
Reliable earthing of rack mounted equipment must be maintained. Particular attention
should be given to supply connections other than direct connections to the branch
circuit, such as mains distribution strips that are typically located inside equipment
cabinets.
NOTE
Read the safety information in Appendix B: before installing any
equipment.
1.1.7 Connecting AC power
Each AC power module has a 3 pin socket as shown below (C).
Standard IEC 60320 type C13 power cords provide the AC power and earth
connections. Both modules must be connected to provide power module redundancy.
