5-Port Gigabit Ethernet SPA Overview Chapter 3 Overview: Cisco ASR 1000 Series Aggregation Services Routers SPAs Figure 3-16 RJ-45 Connector Pinouts, Plug, and Receptacle 205060 8 7 6 5 4 3 2 1 RJ-45 connector Table 3-11 RJ-45 Connector Pinouts Pin Description 1 DA_P (bidirectional pair A, plus) 2 DA_N (bidirectional pair A, minus) 3 DB_P (bidirectional pair B, plus) 4 DC_P (bidirectional pair C, plus) 5 DC_N (bidirectional pair C, minus) 6 DB_N (bidirectional pair B, minus) 7 DD_P (bidirectional pair D, plus) 8 DD_N (bidirectional pair D, minus) Note Referring to the RJ-45 pinout in Table 3-11, proper common-mode line terminations should be used for the unused Category 5 UTP cable pairs 4/5 and 7/8. 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
