7450 ESS-7

IOM

S

The 7450 family of switches support a wide variety of interfaces, including Ethernet, SONET/SDH
(channelized and concatenated) and ATM. Each input/output module (IOM) features a single-slot
baseboard carrying up to two hot-swappable MDAs.

MDA

S

Alcatel-Lucent’s Ethernet MDAs for the 7450 ESS provide the critical high-speed interfaces. An
MDA is a plug-in module allowing selection among fiber-optic, twisted pair, and coaxial cable. A
maximum of 2 MDAs can be installed on each IOM.

See

Appendix A: LEDs and Optics on page 109

for LED descriptions.
