1

16-port switch front panel

2

QSFP ports 1-16

These ports can be assigned by their port numbers for the following permanent connection roles:

  • CNode ports, which connect to the CNodes.

  • DNode ports, which connect to the DNodes.

  • External ports used for uplinking to the client data network.

  • Interconnect ports connect two switches in a pair to each other. This is used to configure an MLAG interface between two switches.

Consult the installation plan to establish the correct port assignments for the installation.

3

Management port

  • Connection to GbE management switch

  • Connection from switch to switch in a B2B IPMI connection scheme.

4

Power connectors

Connection to rack PDUs, for power supply.
