There are many models – with and without PoE+, with and without stacking, with and without 10GbE ports. Note that you can use SummitStack-V over the 10GbE links. While the primary GE interface is copper, ALL models have some amount of fiber GE connections.
The Summit X440 doesn’t need a bulky, high-cost cooling system because its power consumption ranges from 39 to 60 watts for non-PoE+ models to 380 watts for the highest level PoE+ model. On several models, the fan shuts off at temperatures below 30 degrees Celsius, while the fan on the Summit X440-8t model is controlled through bandwidth.
All the Summit X440 models are the same height and depth. While most are 17.4 inches wide and fit easily into a standard rack, the Summit X440-8t and Summit X440-8p models are 12 inches wide and will need rack-mount ears installed to occupy a rack slot.
The Summit X440 supports an access platform, while the Summit X450 and Summit X460 serve as aggregation devices. Therefore, the Summit X440 offers smaller routing and host entry tables, as well as just a 32-entry maximum on the IPv4. These smaller resources easily support access networks that require only a few routes to interconnect several VLANs.It’s also important to note that the Summit X440 and Summit X450 have ingress ACLs, but no egress ACLs. Larger networks might require the Summit X460, which includes both ingress and egress ACLs.
