Cisco 900 Series Aggregation Services Routers (ASR) - Refurbished, Used, New
Cisco ASR 900 Series Aggregation Services Routers are modular edge and pre-aggregation routers for service provider access, mobile backhaul and utility networks, running IOS XE with MPLS, SyncE and IEEE 1588 timing. The ASR 902, ASR 903 and ASR 907 chassis take Route Switch Processors (RSP1, RSP2 and RSP3) and A900-IMA interface modules that range from T1/E1 and OC-3 circuits up to 10G and 100G Ethernet, so one router can carry legacy TDM services alongside Ethernet. The fixed ASR 9901 and its power supply are also listed here. NetworkTigers sells ASR 900 chassis, RSPs, interface modules, power supplies, fan trays and console kits refurbished, used and new. Every unit is tested before it ships so it works when it arrives.

Which ASR 900 parts do I need?
Choose the RSP by the throughput and the interface modules you plan to run. The RSP1 and RSP2 suit 1G and TDM-heavy sites; the RSP3 is required for the 10G-dense and 100G modules such as the IMA8Z and IMA1C, and the RSP3 draws more power, so a 903 with an RSP3 and several 10G modules needs the enhanced A903-FAN-E fan tray and matching power supplies. Pick interface modules by service type: IMA8S or IMA8T for 1G customer handoffs, the 1Z versions when you want a 10G uplink on the same card, IMA8D or IMA32D for T1/E1 circuits and IMA4OS for OC-3/OC-12. Specify AC or DC input, and order two supplies for redundancy. Each interface module and RSP has a minimum IOS XE release, so send us your chassis, RSP, module list and software version and we will confirm the combination is supported before you order.
Frequently asked questions
Can I run two different RSPs in one ASR 903 for redundancy?
No. Redundant RSPs must be the same model, so a 903 with an RSP2A-128 needs a second RSP2A-128, and moving to RSP3 means replacing both.
Do the ASR 902 and ASR 903 use the same interface modules?
Yes. The A900-IMA modules fit the ASR 902, 903 and 907, with the 902 limited to the modules its RSP and slot count support. The fan trays and some power supplies differ between the chassis, so match those to the exact model.
Why is the ASR 9901 on this page?
The ASR 9901 is a fixed router from the ASR 9000 family that is often bought by the same service provider teams that run ASR 903s. It runs IOS XR rather than IOS XE and uses its own A9K power supplies, so do not mix its parts with the ASR 900.
NetworkTigers has sold enterprise network equipment since 1996. Every router, RSP and module carries the NetworkTigers 365-day warranty. Need a full chassis build or several interface modules? Ask us for a quote.
