CN4093 Installation Guide
The CN4093 provides support for Layer 2 and Layer 3 switching, as well as a full
set of converge features:
 Converged Enhanced Ethernet (CEE) including Fibre Channel over Ethernet
(FCoE) over all Ethernet ports, including Omni Ports acting in Ethernet mode.
 Priority‐based Flow Control (PFC), Enhanced Transmission Selection (ETS) and
Data Center Bridging Capability Exchange (DCBX).
 N_Port Virtualization (NPV) Gateway and Full Fabric Fibre Channel Forwarder
(FCF).
 Full fabric Fibre Channel (FC) services, including Name Server and
hardware‐based Zoning.


Single Root I/O Virtualization (SR‐IOV) capability.
The CN4093 provides pay‐as‐you‐grow scalability. With optional licensing, you
can easily and cost‐effectively expand the number of available ports.
The base license provides support for the following:
 Single compute node port capability, consisting of fourteen internal 10 Gigabit
Ethernet (GbE) with FCoE and auto‐negotiation capability)
Two external 10 GbE/FCoE Small Form‐factor Pluggable Plus (SFP+) ports

which also support legacy 1 GbE/FCoE connections
 Six Omni Ports, allowing each port pair to be used as either two 10 GbE/FCoE
SFP+ optical ports or as FC ports independently capable of 4 or 8 Gigabits per
second (Gbps)
Additional ports are available with optional licenses. There are two upgrades that
are available for the CN4093 (see "Acquiring Feature Licenses" on page
Upgrade 1 adds supports for the following:
 Fourteen additional internal 10 GbE/FCoE compute node ports
 Two external 40 GbE/FCoE Quad Small Form Pluggable Plus (QSFP+) ports,
each of which can be optionally used as four 10GbE/FCoE SFP+ ports
Upgrade 2 adds support for the following:
 Fourteen additional internal 10 GbE/FCoE compute node ports
 Six additional Omni Ports
Note: Upgrade 1 and Upgrade 2 are independent and can be installed in any order,
with or without the other.
SFP+ ports can be populated with 10 Gb optical or copper SFP+ transceiver modules
or Direct‐Attach Cables (DACs), or legacy 1 Gb optical or copper SFP transceiver
modules.
Omni ports ports can be populated with 10 Gb optical SFP+ transceiver modules or
DACs.
QSFP+ ports can be populated with optical QSFP+ modules or DACs, including
some that accept SFP+ or SFP modules.
