Description

The Arista 7388X5 is a compact 4RU modular data centre switch built around a single 25.6 Tbps packet processor. This SKU is the bundle with eight 8-port 400G QSFP-DD MACsec interface modules, giving 64 x 400G ports in total with front-to-rear airflow. It suits leaf or spine roles in hyperscale cloud networks, AI/ML clusters, big data farms and I/O-intensive data centre environments that need high-radix 200G and 400G.

The chassis provides 8 interface module slots and 1 supervisor slot, with system capacity of 25.6 Tbps and 10.66 Bpps, latency from 825 ns and a 114 MB shared packet buffer. Each QSFP-DD port supports 100G, 200G or 400G speeds, and 10G, 25G and 40G through breakout or optics. Power is provided by N+N redundant hot-swap AC supplies with N+1 fans, and maximum system consumption is 3,458 W in this configuration. The switch runs Arista EOS and operates as a Fixed - Group 4 platform, with optional feature licences ordered separately, including MACsec encryption.

The DCS-7388-CH chassis also accepts the DCS-7388-16CD2, DCS-7388-8DR and DCS-7388-8D interface modules, and requires EOS 4.29.1 or later. It works with industry-standard 10G to 400G pluggable optics and cables.

FAQs

Q: Does this switch need a licence?
A: It runs Arista EOS as a Fixed - Group 4 platform. Optional feature licences are ordered separately, such as LIC-FIX-4-E for enhanced Layer 3 routing and LIC-FIX-4-MACSEC for MACsec encryption.

Q: What power supplies does it use?
A: The chassis takes up to four PWR-2421-HV-RED 2400 W supplies in an N+N redundant arrangement, with 200-277 VAC input. A DC variant, PWR-2411-DC-RED, is also available.

Q: Which interface modules work in this chassis?
A: The DCS-7388-CH chassis accepts the DCS-7388-8D (8 x QSFP-DD MACsec), DCS-7388-8DR (8 x QSFP-DD) and DCS-7388-16CD2 (16 x QSFP56) interface modules.

Q: What EOS version does it require?
A: It requires Arista EOS 4.29.1 or later.

Q: What does the front-to-rear airflow variant mean for installation?
A: Cool air is drawn in at the front of the chassis and exhausted at the rear. The fan trays for this arrangement are FAN-7012HP-RED and FAN-7012MP-RED.
