Specifications include, but are not limited to: 1.Core switching configuration must be able to do Layer 2/Layer 3 (routable) switching, as this purchase will replace existing routers for several CCOM VLANs. 2.Switch hardware must be physical stack or spine/leaf style, not chassis style. Like switch models in this configuration must be able to logically stack, though not explicitly required if the required software management solution (see below) allows for single logical management interface of all switches in this configuration.3.Preferred form factor would be 1U switches with at least 24 ports for endpoint connectivity each, as well as supplemental ports for switch interconnect.4.Each individual switch appliance must have redundant power. Power supplies must be able to operate at 100-240V, and each switch must ship with power cables that can be plugged into the IEC C14 receptacles on our server rack power distribution units.5.Total switching configuration cannot exceed 14U in standard 19" server rack space.6.Must be a fully redundant network switching configuration - no single point of failure will result in loss of network connectivity across the entire configuration.7.Must be able to add additional switches to the stack without loss of connectivity to the entirety of the switching configuration.8.At least 288 x 1Gbps ports w/RJ45 copper connectivity.9.At least two of the 1Gb/RJ45-capable switches in the configuration must have Power-over-Ethernet (PoE) capability at IEEE 802.3 PoE Plus specification (44-57V).10.At least 72 x 10Gbps or 10/25Gbps ports capable of supporting SFP+ optical transceivers. At least 46 x 10Gbps or 10/25Gbps SFP+ multimode optical transceivers (300m) populated at the time of purchase, and 2 x 10Gbps SFP+ single mode transceivers (10km).11.Switch interconnects must have at least 80Gbps capability between 10Gb or 10/25Gb port-capable switches, and capability of at least 40Gbps between 1Gbps port-capable connected switches.12.Terminal, SSH, and individual switch Web UI capabilities required for each switch (though notnecessarily as the primary means of management).
