Troubleshooting steps:

1. Check for the switch details to connect to it with commands:

# isi_dump_fabric int-a
# isi_dump_fabric int-b
# python -c "import isi.net.backendmon.util as u; print (u.intuit_switch_addr(\"int-a\")); print (u.intuit_switch_addr(\"int-b\"))"

2. Connect to the switch and check Power Supply Unit (PSU) status (Make a support case if assistance is required connecting to the switch)
