Network switch issues
If you have any issues that are related to the management or high-speed switches, see ESS – Switch
Update and Configuration Guide.
Note: An IBM intranet connection is required to open this document.
Some important chapters in this document are as follows:
• How to manually set up VLANs on the management switch
• Default passwords and help locating
• Resetting switches back to factory defaults
• Best practice settings
• Changing passwords
• Upgrading switch firmware and recommended levels
SSR port login issues
The workaround given in this topic apply to POWER9 EMS or POWER9 protocol nodes only.
By default, you will be given a DHCP IP when connected to C11-T4 of each node. This IP will
automatically assign the following IP to your laptop:
• IP address: 10.111.222.102
• Netmask: 255.255.255.252
If the ping test fails to the SSR port (10.111.222.101), attempt to set the IP address statically. If a ping
still does not work, the system might be shipped with an old default SSR IP address.
• IP address: 10.0.0.100
• Netmask: 255.255.255.0
Try to set that IP address and attempt ping. If the ping test still does not work (Ensure that the system is
also booted up – apply power and press the front white button. Wait minimum 5 minutes though it could
be up to 20 minutes to boot a data server.) call IBM service.
Assigning the management IP address
This section covers the issues that you might encounter while assigning the management IP address by
using the essutils tool. This task requires knowledge of the Linux command line and the Vi editor.
1. Log in as the root user with the password ibmesscluster .
You are prompted to change the password. Change the password back to ibmesscluster .
2. To edit the ifcfg-enP1p8s0f0 file (or the ifcfg-enP1p8s0f1 file if the interface is EMS FSP interface):
cd /etc/sysconfig/network-scripts
Press Enter.
vi ifcfg-<devicename>
Press Enter.
Note:
If you need to modify the management interface, use the device name for the EMS as enP1p8s0f0 .
If you need to modify the FSP interface (EMS only), use the device name for the EMS as enP1p8s0f1.
