Cisco Systems CGS 2520 manual SD Flash Memory Card, Power Supply Side, Dual-Purpose Port LEDs

Chapter 1 Product Overview

SD Flash Memory Card

Dual-Purpose Port LEDs

The dual-purpose port LEDs identify the connection as either a copper-based connector or an SFP module. The ports can autonegotiate, or you can manually configure each dual-purpose port as either 10/100/1000 with copper connectors or as an SFP module port, but not as both types at the same time. See Table 1-8for LED descriptions.
