Each VX640 I/O card has 20 SFP+s, each mounted within a grounded metal enclosure. Each SFP+
module is locked into its enclosure with a built-in latch handle that can be opened for removal or locked
for installation.

The latch handle spans the two LC ports. Arrows printed on the handle indicate which port is an INPUT
(

).
Input/Output Cards
The hot-swappable Input/Output (I/O) cards provide excellent in-service expansion capabilities in
convenient sets of 20 ports per card, allowing re-configuration without interrupting signal processing. The
VX640 Router will support up to 32 Input/Output Cards.
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 VX640 I/O Card numbers the ports 1 through 20. An LED located on each card indicates
when power is applied to that card.
