Power Connection

The host has a modular DC to DC power

supply located on the lower left side ofthe chassis.

The host is powered by 20Vdc to 60Vdc

power (nominal 24Vdc 48Vdc).

Computer Connection

In the default configuration, the Craft port has

a DHCP server that assigns an IP address to

computer that is connected. You should

therefore have your network interface

configured for DHCP, or configured with static

IP address in the same subnet, where thedefault is 192.168.0.1/24.

Optical Connections

Improper handling can damage fiber optic

cables. Do not bend fiber optic more sharply

than the minimum recommended bend

radius specified by the cable manufacturer.

The receivers specification is -9 to -27dBm.

Based on typical fiber runs, theres usually

only a few dB of loss, so the 15dB LC

attenuator ships with each Host to put the

receive level in the optimum receive range.

Coaxial Cable Connections

The composite forward path RF signallevel at the host must be between -25

and +5dBm. Do not connect the forward

path cable until the composite forward

path RF signal level is measured and

amount of external attenuation required

is determined.
