Description

The EX9253 from the Juniper EX9250 range is a compact 3RU modular Ethernet switch chassis built for campus core and aggregation roles and on-premises data centres. It runs Junos OS and suits wiring-closet aggregation of EX2300, EX3400, EX4300 and EX4600 access switches, as well as Evolved Enterprise Core designs using EVPN-VXLAN, Junos Fusion Enterprise and Data Center Interconnect, with a path to a 100GbE core.

This redundant AC configuration is fitted with two EX9253-RE Routing Engines in a 1+1 arrangement, four JNP-C1-FAN-3RU fan trays and four 1600 W JNP-PWR1600-AC-BB AC power supplies. The chassis has three slots, two of which take line cards, and delivers up to 2.4 Tbps per slot. With line cards fitted it scales to 144x 10GbE (breakout), 36x 40GbE or 24x 100GbE wire-speed ports. Maximum power draw is 2692 W from a 100-120 V or 200-240 V AC supply.

Line cards EX9253-6Q12C and EX9253-6Q12C-M (MACsec) are used with this chassis, together with Juniper SFP+, QSFP+ and QSFP28 optics and DAC cables. BGP, IS-IS and MPLS capabilities need the EX9253-AFL Advanced Feature License.

FAQs

Q: Does the EX9253-RED-AC need a licence?
A: It runs Junos OS with base L2/L3 features. BGP, IS-IS and MPLS capabilities need the EX9253-AFL Advanced Feature License. The EX9253-ML licence raises FIB/ARP entries from 256,000 to 512,000, and EX9253-SFL enables MACsec on the EX9253-6Q12C-M line card.

Q: What power does this chassis need?
A: It uses four JNP-PWR1600-AC-BB 1600 W AC supplies on 100-120 V or 200-240 V AC, with 3+1 redundancy. Maximum draw is 2692 W. AC and DC supplies cannot be mixed in one chassis, and the supplies use C19 power cords.

Q: Which line cards work with the EX9253?
A: The EX9253-6Q12C (12x 40/100GbE QSFP28 and 6x 40GbE QSFP+) and the EX9253-6Q12C-M, which adds MACsec. Two of the three slots take line cards.

Q: Which optics work with this switch?
A: Juniper SFP+, QSFP+ and QSFP28 optics and DAC cables, for example EX-SFP-10GE-SR, EX-SFP-10GE-LR, QFX-QSFP-40G-SR4, JNP-QSFP-100G-SR4 and JNP-QSFP-100G-LR4.

Q: How does this SKU differ from a single Routing Engine version?
A: This redundant configuration has two EX9253-RE Routing Engines in a 1+1 arrangement and four 1600 W AC power supplies, so the control plane and power both have redundancy.
