Suits 10 GbE leaf deployments needing

This switch fits data-centre rows that exhaust heat toward the cold aisle. It serves networks that require 24 SFP+ ports and out-of-band management without built-in uplink modules. Buyers who need front-to-rear airflow or integrated uplink ports should evaluate other models. Environments requiring rack-mount hardware in the box must source brackets separately.

24 SFP+ ports with rear-to-front airflow

The port count and airflow direction are the decisive factors for rack compatibility. Twenty-four SFP+ interfaces support 1 GbE or 10 GbE transceivers. Rear-to-front cooling matches cold-aisle exhaust layouts. Confirm that your cabinet design and transceiver selection align with these two fixed attributes before purchase.
