2-Port, 4-Port, and 8-Port OC-12c/STM-4 POS SPA Overview Chapter 3 Overview: Cisco ASR 1000 Series Aggregation Services Routers SPAs Table 3-28 OC-12 Specifications (continued) Specification RX overload Maximum receiver power damage Description OC-12 MM: -6 dBm OC-12 SR: -8 dBm OC-12 IR-1: -8 dBm OC-12 LR-1: -8 dBm OC-12 LR-2: -8 dBm OC-12 MM: 5 dBm OC-12 SR: 5 dBm OC-12 IR-1: 5 dBm OC-12 LR-1: 5 dBm OC-12 LR-2: 5 dBm 2-Port, 4-Port, and 8-Port OC-12c/STM-4 POS SPA Overview The 2-Port, 4-Port, and 8-Port OC-12c/STM-4 Multirate POS SPA is a single-height SPA that installs into one SIP subslot. For the OC-12 SPAs, any given channel can be configured as either OC-3 or OC-12, so the per-port bandwidth can be either 155.52 Mbps or 622.08 Mbps respectively, depending on the customer configuration. Note When SFP modules are replaced, the SPA interface retains any previously-defined configurations. These configurations include settings for IP address, clock source, loopback, CRC, and POS flags. The 8-port OC-12c/STM-4 POS SPA is a full-rate SPA; therefore, it can only be installed in subslots 1 or 2 of the SIP. The 2-Port OC-12c/STM-4 POS and 4-Port OC-12c/STM-4 POS SPAs are half-rate SPAs. The following sections describe the 2-Port, 4-Port, and 8-Port OC-12c/STM-4 Multirate POS SPA: • 2-Port, 4-Port, and 8-Port OC-12c/STM-4 Multirate POS SPA LEDs, page 3-48 • 2-Port, 4-Port, and 8-Port OC-12c/STM-4 Multirate POS SPA Interface Specifications, page 3-49 • 2-Port, 4-Port, and 8-Port OC-12c/STM-4 Multirate POS SPA Optical Transceiver Modules, Connectors, and Cables, page 3-50 2-Port, 4-Port, and 8-Port OC-12c/STM-4 Multirate POS SPA LEDs The 2-Port, 4-Port, and 8-Port OC-12c/STM-4 Multirate POS SPA has three LEDs: two LEDs for each port on the SPA, and one STATUS LED as shown in Figure 3-32. Note Three different faceplates exist for the 2-Port, 4-Port, and 8-Port OC-12c/STM-4 Multirate POS SPAs. They each contain the same LEDs and the number of ports are 2, 4, and 8 respectively. 3-48 Cisco ASR 1000 Series Aggregation Services Routers SIP and SPA Hardware Installation Guide OL-14126-12
