2.2. MOUNTING
The XRF1 occupies 1RU of rack space and fits into a standard 19” rack. The dimensions 19”W x 1.75”H x
18.75D ( 483mm x 45mm x 477mm ). RF, Ethernet and serial port connections are located at the back of
the unit. Forced-air cooling is through the sides of the unit, therefore extra space above and below is not
required.
2.2.1. RF
Connections
The 16 RF inputs are located in the central portion of the rear panel, and the 16 outputs are located on
both sides of the central input connectors. Outputs 1-8 on the left side (when facing the rear panel) and
outputs 9-16 on the right side.
Note for XRF1 model only: If equipment connected to the router supplies DC
via coax, this DC MUST be turned off or otherwise blocked. Damage to the
router can result if DC is applied to the RF in/output ports. This does not
apply to the XRF1A.
When equipped with 75-Ohm F-Type coaxial connectors, these connectors
accept conductors in the range of 21-19 AWG (0.41-0.64 mm
2
). Using a larger
conductor will damage the connector. If you are using cable with a center
conductor larger than 19 AWG (0.64 mm2), a connector with a fixed or crimp
pin of a suitable diameter must be used (i.e. Amphenol Connex 222123 (for
RG6) or Canare FP-C series).
2.2.2. Power
Connections
The AC input voltage for the XRF1 power supply is auto ranging, 100 to 240 VAC, 50/60Hz. Maximum
power dissipation for the frame is 175 Watts (LNB option) or 40 Watts (non LNB option).
2.3. POWER
REQUIREMENTS
Each power supply in the chassis is powered by a separate AC connector, each of which is independent of
the other power supply in the chassis. In a chassis that contains a 2nd (redundant) power supply module,
each power supply may be powered from a different AC mains source, allowing complete AC supply
redundancy. In this case, the unit will be powered from one supply and will automatically switchover to the
secondary supply in case of failure. There are two LEDs on the front panel to indicate the health of the
power supply units (PSUs). These LEDs will be lit (green) when the PSU is ok and off when there is a
problem with the supply.
