EMS issues
EMS Boot issues
When booting up the node, if you face any issue while pinging the FSP interface (C11-T4 IP
110.111.222.101) 5 minutes after pressing the white button, perform the following checks:
• Verify if the Ethernet cable on both the ends has a solid green light.
• Check if your laptop is set to IP 10.111.222.102 and netmask 255.255.255.252.
• Verify that you are plugged into the correct port – C11-T4 on the EMS.
If the issues still persist, shut down the node (hold the white button until blinking again) and perform the
following steps:
1. Connect the laptop point-to-point over serial connection, connecting the USB to RJ45 console cable
between the auxiliary laptop and the serial port of the server with active ASMI session from the
previous section.
Note:
• The USB to RJ45 console cable shown in the Figure 20 on page 41 works for Linux and Windows
laptops.
• Identify the right console cable when using an Apple laptop.
