Juniper Switches and Routers

Used and refurbished Juniper switches, routers and firewalls, each listed with its part number, condition and price. Juniper's EX and QFX Series are Ethernet switches, its MX and ACX Series are routers and its SRX Series are firewalls, so this page holds all three kinds of box, plus MX line cards, Routing Engines and JPSU power supplies. The Part type filter below separates them, and each family page opens one series with the maker's figures beside the listings. How we test used Juniper hardware Each unit is logged by serial number and inspected: chassis, ports, fans, power supplies and optics cages. It then runs under power long enough to surface early failures, with power supply output, fans and temperatures checked under sustained load. Our technicians test every port and module slot for link at rated speed, clean error counters and a reachable management interface. The previous owner's configuration is erased and the unit is returned to a clean factory state, then it is checked again before it is packed. The condition on each listing is the grade our bench assigned. The full procedure is on the testing process page. Warranty and returns The Townsend 3-Year Warranty covers hardware failure in normal use for 3 years from the date of delivery, including ports, power supplies, fans, backplanes and module slots. If a unit fails, we repair it or replace it with an equivalent tested unit. Unused hardware in the condition it shipped can be returned within 30 days of delivery for a refund; contact us for an RMA number before shipping anything back. We are an independent reseller, so the warranty is our own and Juniper software licensing and support contracts are outside it. Read the 3-year warranty and RMA terms and the refund policy. Prices and quotes Every listing shows its price, and you can buy at that price through checkout. Prices differ by model, port count, feature set and condition, so sort this page by price or open a family page below to compare like with like. For several units, a mixed list or a Juniper part number you do not see here, send part numbers and quantities through request a quote: a firm price comes back, typically the same business day. We accept major credit cards, ACH and wire transfer, and net terms are available for qualified businesses. Juniper families we list EX Series switches: from the EX2300 to the EX4650. The EX2300 joins up to four switches in a Virtual Chassis, and the EX3400, EX4300, EX4400 and EX4600 up to 10, the EX4300 at 320 Gbps and the EX4400 at 400 Gbps.

Questions about used Juniper equipment Is the Juniper MX a switch or a router? A router. Juniper's own documents call the MX Series Universal Routing Platforms: the MX204 hardware guide describes a 1U router with 400 Gbps of throughput, and the MX480 is an 8 slot, 8U router chassis. The switches on this page are the EX and QFX Series. Sources: MX204 Universal Routing Platform Hardware Guide, MX480 Universal Routing Platform Hardware Guide. What do AFO and AFI mean at the end of a Juniper part number? They name the airflow. AFO models move air front to back (airflow out) and AFI models move air back to front (airflow in). Juniper lists the ACX5448, for example, with front-to-back airflow (AFO) or back-to-front airflow (AFI). Sources: ACX5448, ACX5448-D, and ACX5448-M System Overview, QFX5120 Ethernet Switch Datasheet. Are the ACX5448 and the ACX5448-D the same router? No. The ACX5448 has forty-eight 1/10GbE SFP+ or SFP ports and four 100GbE QSFP28 ports. The ACX5448-D has thirty-six 1/10GbE SFP+ or SFP ports, two 100GbE QSFP28 ports and two CFP2-DCO ports that run at 100 or 200GbE.
