EX4300-32F Overview
Separate fixed ports from expansion
The base EX4300-32F has two QSFP+ ports, not four. An optional EX-UM-2QSFP adds two more; alternatively, EX-UM-8X8SFP provides eight SFP+ positions. Specify the installed module when comparing quotations rather than treating the expanded maximum as the base configuration.
Check the AC package and rack depth
Juniper lists a 350 W AC supply and two AIR OUT fan modules for this order. The -DC and -S identifiers describe different packages. Verify actual components on a replacement unit. With the supply and front module fitted, manufacturer dimensions are 44.1 x 4.37 x 49.1 cm (width x height x depth), before allowing space for cables.
Lifecycle-aware replacement
Juniper notice TSB105633 lists March 31, 2026 as last order and March 31, 2029 as end of support for EX4300-32F. These milestones are not a guarantee of stock or an individual unit’s service entitlement.
