Hardware Overview
46 Enterasys X-Pedition 8000/8600 Getting Started Guide
SSR-POS29-04 and SSR-POS21-04
The SSR-POS29-04 and SSR-POS21-04 modules provide high-speed connectivity to SONET
networks. These modules support ACL-based filtering, Layer-4 application-aware switching, QOS
features, and Server Load Balancing. The SSR-POS29-04 and SSR-POS21-04 are available as
4-port OC-3 SMF or MMF models and are compatible with the X-Pedition 8000/8600 hardware
platforms. The POS OC-3c line cards use MT-RJ connectors to attach to multimode fiber (MMF)
and single mode MT-RJ cables. To attach the segment cables to a POS OC-3c line card, obtain an
MT-RJ cable and plug one end into the port connector. Plug the other end into the port of the other
device. Since MT-RJ cables consist of only one line, there are no concerns about matching the
receive port with the transmit port.

Note: If your system uses a redundant power configuration or only one power supply, you will
not be able to support more than 5 SSR-POS29-04 and SSR-POS21-04 cards in the
X-Pedition 8000 and 10 in the X-Pedition 8600.
