The following table shows connections from each server to the switch ports with a 100 G NIC in PCI Slot2 connected to a S5232F-ON switch:

Table 1. Server-to-switch port connections in the deployment

The following table shows the firmware versions that are supported for the switch models:

Table 2. Switch model and firmware specifications

Dell EMC switch model	OOB management IP	Firmware version	Default username	Default password
S3048-ON	100.82.33.46	10.5.0.2	admin	admin
S5232F-ON	100.82.33.45	10.5.0.2	admin	admin

To modify the switches for your environment:

Download the switch config files from GitHub by running the following command:

git clone https://github.com/dell-esg/openshift-bare-metal.git

Modify the sample switch config files to match your VLAN and IP schemes.

The deployment utilizes untagged VLANs that use switchport access for nodes and tagged port-channels for switch uplinks.

The deployment sample uses:

VLAN_461 configured for Public a /26 network
Dedicated iDRAC VLAN_34 /24 network and a dedicated /24 switch out of band (OOB) management network
Single port on 100 G Mellanox X5 DP NIC in PCI Slot 2

Note: The serial port baud-rate is 115200.
