This Installation Guide provides information and instructions for installing NEC PF5820.
For information about configuration and management of the switch,
see the Command Reference and the product release notes.
PF5820 is a rackable aggregation switch with unmatched line-rate
Layer 2/3 performance. PF5820 uses a wire-speed, non-blocking switching
fabric that provides simultaneous wire-speed transport of multiple packets at low
latency on all ports.
PF5820 contains forty-eight 10 GbE SFP+ ports and four 40 GbE QSFP+ ports.
The SFP+ ports can be populated with optical or copper transceivers, or Direct
Attach Cables (DACs). The QSFP+ ports can be populated with optical QSFP+
transceivers or DACs.
This 1U switch is rack mountable in either the horizontal or vertical direction,
depending on your application.
You can manage the switch through the console port, or through a network
connection using Telnet, a Web browser-based interface, or SNMP-based network
management software.
