Description

The Juniper EX9253-CHAS-3RU is the bare 3RU, 3-slot chassis for the EX9200 series EX9253 core and aggregation Ethernet switch. It suits compact campus cores and on-premises data centres that need to aggregate EX2300, EX3400, EX4300 and EX4600 access switches.

This is the chassis-only SKU, so it does not include the Routing Engine, power supplies or fan trays that come in the EX9253-BASE and EX9253-RED bundles. The chassis supplies the midplane, fan tray bays and power supply bays, with two line card slots plus Routing Engine slots for 1+1 redundancy. System throughput reaches 4.8 Tbps, or 2.4 Tbps per slot, with up to 144 x 10GbE (using breakout), 36 x 40GbE or 24 x 100GbE at wire speed. Up to six AC or DC power supplies run in 3+1 redundancy, with a maximum system power draw of 2692 W.

It works with EX9253 line cards including the EX9253-12C8Q-M, the EX9253-RE Routing Engine, JNP-C1-FAN-3RU fan trays, JNP-PWR1600-AC and JNP-PWR1100-DC power supplies, and EX9253-LC-BLNK blank panels. The switch runs Junos OS, and advanced Layer 3 features such as BGP, IS-IS and MPLS need the Advanced Feature License.
