Cobalt Digital RM20-9915-A-HDBNC is a 20-slot frame rear I/O module with four 12G/3G/HD/SD-SDI inputs and sixteen 12G/3G/HD/SD-SDI outputs for use with Cobalt's 9915DA Multi-Rate Reclocking DA's.. It works as a rear module for the Cobalt card part# 9915DA-2x16-XPT-12G .
Notes:
Rear module has factory-installed SFP module receptacles on rear module. Plug-in SFP functionality is available with option -DA-SFP (SFP support daughtercard) and SFP plug-in module options.
On 9915DA-2x16-12G model, SFP cage 1 supports only Rx (OE) type SFPs. SFP cage 2 supports only Tx (EO) type SFPs.
SFP modules, when inserted into rear module SFP receptacles, can dimensionally extend past the right "boundary" of the rear module. In rare cases, this can present interference issues if a rear module to the right of SFP rear module also has adjacent large-footprint connectors that can extend across the rear module boundary. Plan frame buildout accordingly in these cases.
