Input/Output Cards
The hot-swappable Input/Output (I/O) cards provide excellent in-service expansion capabilities
in convenient sets of 5 ports per I/O card for the HDX80 or sets of 16 ports per I/O card for the
HDX320 and HDX576, thus allowing re-configuration without interrupting signal processing.
Each I/O card consists of one Transmit (T) and one Receive (R) optic per port. I/O Cards are
available with LC-type fiber connectors and can be assembled with Single-mode or Multi-mode
optics (SFP+). Each individual I/O Card lists the ports as 1 through 5 on the HDX80 and as 1
through 16 on the HDX320 and HDX576 Video. The Fan Tray module lists the port numbers
(all numbering is bottom to top, left to right. See figs. 10-12 on pg. 13). A LED located at the
top of each I/O card indicates when power is ON to that card.
The HDX80 Router configuration can have a minimum of one I/O Card. The HDX80 Router is
constructed with one fully non-blocking 80x80 switch matrix.. Each HDX80 I/O card contains 5
ports, so that when fully configured, the HDX80 will contain 16 I/O cards. The 16 I/O cards
provide a total of 80 Optical Input/Output connections (SFP+ T/R). The switching matrix
connects any optical input (SFP+ R) to any optical output (SFP+ T), even if it is the same Port
number (i.e. Port 1 R connected to Port 1 T).
