3.1 Connections to OOB management switch

The OOB management network is an isolated network for remote management of servers, switches, and

other devices. It is also used to carry heartbeat messages sent between leaf switches configured as VLT

peers.

Dell EMC recommends using at least one S3048-ON switch per 42-RU rack for OOB management network

connections. Each S3048-ON has forty-eight 1GbE Base-T ports for connections to server iDRACs and leaf

switch management ports as shown in Figure 7. Four 10GbE SFP+ ports are available on the S3048-ON for

uplinks to the OOB management network core (links not shown).

Note: When running OS10EE, the S3048-ON will function as an OOB management switch with its factory

default configuration. By default, all ports are in switchport mode, in VLAN 1, administratively up, and rapid

per-VLAN spanning tree plus (RPVST+) is enabled. At a minimum, Dell EMC recommends changing the

admin password to a complex password during the first login.
