ASR5K-C4OC3-SM-K9= is the spare/replacement ordering form for Cisco's CLC2 Channelized four-port STM-1/OC-3 line card with single-mode SFPs. It is a rear line card for the ASR 5000 platform, not a complete chassis, packet-processing card, software license or support service.
Cisco describes CLC2 as a Frame Relay line card for SGSN packet-control-unit connectivity. It exposes four LC duplex ports and channelizes 155.52-Mbps links into as many as 336 T1 or 252 E1 channels.
The equals suffix is material: this is the spare form intended for replacement inventory. Verify that the receiving ASR 5000 has the matching rear-card slot, processing-card relationship, software support and single-mode plant before accepting it as a field spare. Record the failed-card serial, anti-static packaging, replacement serial and return-material disposition; a loose board without traceable spare provenance is not sufficient acceptance evidence.
Cisco ended sale on January 30, 2016 and ended hardware support on January 31, 2021, with no replacement PID listed in the bulletin. Acceptance should include four-port detection, the required channelized mode, T1/E1 hierarchy checks, LC/SFP inventory and an APS/redundancy test where the deployment uses a standby card.
