ASR5K-4OC3C-SM-K9 Cisco ASR 5000 Line Card OLC2 4-Port OC-3c SM

ASR5K-4OC3C-SM-K9 OLC2 ATM Single-Mode Line Card

ASR5K-4OC3C-SM-K9 is the non-spare system ordering form for Cisco's OLC2 ATM four-port STM-1c/OC-3c 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.

Clear-channel OLC2 role

Cisco identifies OLC2 as the four-port optical ATM line card. Its clear-channel STM-1c/OC-3c role is different from the CLC2 Frame Relay card even though both use four single-mode optical interfaces.

System PID control

This non-spare PID was ordered as part of a system configuration rather than as an equals-suffix replacement. For installed-base procurement, verify whether the customer actually needs a system-form record or the corresponding spare PID; the physical interface role does not change the ordering distinction. Reconcile the original chassis BOM, active/standby card placement and factory configuration record, because a system-form line item should not be presented as an independently boxed field spare.

Lifecycle and acceptance

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, correct ATM STM-1c/OC-3c framing, optical diagnostics for each single-mode SFP and traffic testing against the exact packet-processing card and StarOS release.
