Common-mode termination reduces the contributions to electromagnetic interference (EMI) and susceptibility to common-mode sources. Wire pairs 4/5 and 7/8 are actively terminated in the RJ-45 port circuitry in the 2-Port Copper and Optical Gigabit Ethernet SPA. The 2-Port Copper and Optical Gigabit Ethernet SPA supports automatic MDI/MDIX crossover at all speeds of operation allowing the SPA to work with straight-through and crossover Ethernet cables. 5-Port Gigabit Ethernet SPA Overview The following sections describe the 5-Port Gigabit Ethernet SPA: • 5-Port Gigabit Ethernet SPA LEDs, page 3-20 • 5-Port Gigabit Ethernet SPA Connectors, page 3-22 5-Port Gigabit Ethernet SPA LEDs The 5-Port Gigabit Ethernet SPA has two types of LEDs: an A/L LED for each port on the SPA, and one STATUS LED, as shown in Figure 3-17. 3-20 Cisco ASR 1000 Series Aggregation Services Routers SIP and SPA Hardware Installation Guide OL-14126-12
