System specifications
The Flex System EN4023 10Gb Scalable Switch has the following specifications:
Internal ports:
42 internal full-duplex 10 Gigabit ports (optional Upgrade 1 and Upgrade 2 license upgrades are
required to activate all ports).
Two internal full-duplex 1 GbE ports that are connected to the chassis management module.
External ports:
Fourteen SFP/SFP+ports (optional Upgrade 1 or Upgrade 2 license upgrades, or both, might be
required to activate all external ports depending on the configuration; see Table 2 for details).
Base module supports 10 Gb Ethernet SFP+ transceivers (support for 10GBASE-SR or
10GBASE-LR) or SFP+ direct-attach copper (DAC) cables. SFP+ modules and DAC cables
are not included and must be purchased with the switch (see Table 3).
Upgrade 3 adds support for Flex Ports (support for 8/16 Gb Fibre Channel SFP+ modules;
supported FC port types include E_Port (connecting to EX_Port only), F_Port, and N_Port
[Access Gateway mode]). FC SFP+ modules are not included and must be purchased with
the switch, if needed (see Table 3).
Two ports for 40 Gb Ethernet QSFP+ transceivers or QSFP+ DAC cables (ports are disabled by
default; an optional FoD license is required to activate them). QSFP+ modules and DAC cables are
not included and must be purchased with the switch, if needed.
One RS-232 serial port (mini-USB connector) that provides an additional means to configure the
switch module.
