Supported Interface Cards
The IPS 4270-20 supports three interface cards: the 4GE bypass interface card, the 2SX interface card,
and the 10GE interface card.
4GE Bypass Interface Card
The 4GE bypass interface card (part numbers IPS-4GE-BP-INT and IPS-4GE-BP-INT=) provides four
10/100/1000BASE-T (4GE) monitoring interfaces. The IPS 4270-20 supports up to four 4GE bypass
interface cards for a total of sixteen GE bypass interfaces. The 4GE bypass interface card supports
hardware bypass.
Figure 5-2 shows the 4GE bypass interface card.

2SX Interface Card
The 2SX interface card (part numbers IPS-2SX-INT and IPS-2SX-INT=) provides two 1000BASE-SX
(fiber) monitoring interfaces. The IPS 4270-20 supports up to six 2SX interface cards for a total of
twelve SX interfaces.
The 2SX card ports require a multi-mode fiber cable with an LC connector to connect to the SX interface
of the sensor. The 2SX interface card does not support hardware bypass.
