• 100–240 VAC Primary Input Power Supply with Press‐fit Fuse Holder
1.3.3.2.2 Rear Panel Optional Features
The following Data Interfaces (for optional hardware and/or FAST‐enabled operation) are
available from Comtech EF Data:
• (1X) Optical Gigabit Ethernet interface via the J7|OPTICAL port (a SFP [Small Form
Factor Pluggable] Module socket).
• (2X) PIIC (Plug‐In Interface Card) slots accommodate the following data interface
options:
o G.703 E3/T3/STS‐1 (34.368/44.768/51.84 Mbps).
o OC‐3 Single Mode and Multi Mode (155.52 Mbps).
o STS‐1 Copper (155.52 Mbps).
o Additional PIIC data interface options (ASI, OC3, HSSI, etc.) will become available
upon request.
• (1X) DB‐9M EIA‐232 connector (J2|REDUNDANCY port) for interoperability with a
separately purchased Comtech EF Data redundancy switch:
o
For 1:1 redundant applications, the CDM‐750 is supported by the CRS‐170A
Redundancy Switch for L‐Band operation, or the CRS‐180 Redundancy Switch for
70/140 MHz operation.
o M:N redundancy support is available using the CRS‐500 M:N Redundancy System.
The CRS‐500 can be used only for CDM‐750 1:10 operation with the 10/100/1000
BaseT Gigabit Ethernet and G.703 E3/T3/STS‐1 data interfaces. The CRS‐500 may
not be used with any other data interface, nor can it be used for redundancy in
MultiStream mode.
The following Rear Panel Rack Support Brackets Kits are available from Comtech EF Data:
• KT‐0000168 4” Rear‐Mounting Support Brackets Kit
• KT‐0000195 10” Rear‐Mounting Support Brackets Kit
