AR6121-S Overview
AR6121-S: separate the WAN and LAN interface plans
AR6121-S is a Huawei NetEngine enterprise router with two Gigabit Ethernet combo WAN interfaces and one 10GE optical WAN interface that also supports GE optics. Its fixed LAN group has one GE combo interface and eight GE electrical interfaces; the documented LAN interfaces can be switched to WAN use.
Keep the S model distinct from the E-S revision
Huawei's comparison table assigns 2 GB of memory to AR6121-S and 4 GB to AR6121E-S. The AR6121-S row lists 1 GB flash, two SIC slots, two USB interfaces and one RJ45 console port. Preserve the exact suffix in the order rather than transferring the E-S memory figure to this device.
Plan expansion and service configuration
The table gives zero WSIC slots by default and one as the maximum configuration. Confirm the required module, slot arrangement, software and feature licenses against the intended deployment. Port availability and a slot count do not establish that expansion cards or optical modules are included.
Verify the installed design
Record which interfaces are assigned to each circuit, their electrical or optical media and the required speed. Compare the delivered model label and memory configuration with the quotation, then verify routing and failover using the agreed configuration. Capacity figures for the wider AR family should not replace validation of this exact order.
