2 Dell EMC recommended switch configuration
The steps in this section show how to configure two Dell EMC Networking S5148F-ON switches with a Link
Aggregation Group (LAG). The switches are interconnected using two of the 100GbE Quad Small Form-factor
Pluggable (QSFP28) ports. The LAG is configured for Dynamic Link Aggregation Control Protocol (LACP).
This example uses physical ports 53 and 54 for the 100GbE interconnect between the two switches.
Note: LAGs for inter-switch connections are mandatory for PS Series, optional for SC Series, and not
connected for Dell EMC Unity iSCSI SAN environments.
Note: The factory default user ID/password is admin/admin.
2.1 Hardware configuration
Note: Do not connect any server NIC or storage controller cables to the switch before performing the
following configuration steps.
1. Power on the two switches.
2. Connect a serial cable to the serial port of the first switch.
3. Using PuTTY or another terminal utility, open a serial connection session to the switch.
4. Open the terminal emulator and configure it to use the serial port (COM1, COM2). Configure serial
communications for 115200 N, 8, 1 and no flow control.
5. Perform all CLI steps from section 2 and section 3 (optional) on switch 1. Repeat this process for
switch 2.
6. Required for PS Series (optional for SC Series and not applicable to Dell EMC Unity): Connect
the interconnect cables between the switches by connecting physical port 53 on switch 1 to physical
port 53 on switch 2, and physical port 54 on switch 1 to physical port 54 on switch 2. See the
interconnect configuration in Figure 3.
7. Connect all server NIC and storage controller cables to the switch.
2.2 Check switch operating system version
OS10# show version
Note: If the active version displayed here is not 10.3.2.x or later, visit the Force10 Portal and download the
latest update for the switches.
2.3 Delete startup configuration
Note: This example assumes a switch is using the default configuration settings. Using the delete startup-
configuration command will set the startup configuration file to its default settings. Always back up your
configuration settings prior to performing any configuration changes.
OS10# delete startup-configuration
Proceed to delete startup-config [confirm yes/no(default)]yes
OS10# reload
System configuration has been modified. Save? [yes/no]no
Proceed to reboot the system? [confirm yes/no]yes
