Installing the Host Unit

Page 84 FlexWave Prism Host, Remote and EMS 5.1 System Reference

Table 3-2 provides a Host power consumption matrix that you should use to calculate

power consumption for your system.

* Add 1W for each SFP added

For example, the power consumption of a fully-loaded Host, with four Dual

SuperDARTs, a SeRF card (that comprises eight SFPs), and a System card would be:

•• Nominal—131W

•• Maximum—148.4W

•• 15% Headroom—171W

Use the following procedure to install the power wiring:

600 Obtain the items listed below:

•• Wire stripper and screwdriver

•• Wire, #18 AWG (1.00 mm) red and black insulated copper wire. Recommended

wire size for the power leads, when fused in the same bay.

611 Turn power switch on power supply OFF.

622 Connect the wires to the designated terminals on the fuse panel.

633 Dress and secure the wires to the rack following local practice. Route wiring away

from sharp edges and secure in place to prevent chaffing and provide strain relief.

644 Route the wires to the terminal block on the Host Power Supply and cut them to

length, allowing sufficient length for termination.

All DC input wiring should be routed away from any sharp edges and properly secured

in place to preve

nt chafing and to provide strain relief. This may be achieved by

tie- wrapping wires to the rack frame

or by a similar means.
