ASR5K-042GE-SX-K9 Cisco ASR 5000 Line Card QGLC Rev2 4-Port GE SX

ASR5K-042GE-SX-K9: second-generation four-port optical deployment and SX patch inventory

ASR5K-042GE-SX-K9 is Cisco's retired QGLC Rev2 primary order: a 4-port 1 Gigabit Ethernet interface card supplied for SX multimode short-haul SFP. It is an ASR 5000 card, not a complete chassis, router or software license.

Order-form boundary

This is the non-equals primary order form. Record the installed chassis, slot, card serial and activation evidence; do not describe it as the separately controlled service-spare SKU.

Physical interface acceptance

Confirm multimode fiber grade, patch length, connector cleanliness, polarity and receive level. Do not substitute a single-mode optic because the connector form appears compatible.

Chassis and slot verification

Before purchase, confirm the exact ASR 5000 chassis, supported slot, installed software release, available power and the maintenance method. Preserve a pre-change configuration and map the 4 interfaces to their intended service endpoints.

Retired-platform control

Cisco lists this order family in the ASR 5000 end-of-sale table. Confirm current support status, available spares and the migration design before using legacy stock for expansion. Acceptance should include card recognition, administrative state, negotiated link, error counters and rollback evidence.
