Symptom Probable cause
Failure to access a slave device

One of the following issues occurs on the master device:

Network connection is lost.

Power is lost.

The Ethernet or wireless interface is disabled.

One of the following issues occurs on the slave device in
question or any upstream device (if available):

Connection of the cascading cable is loose or lost.

No power supply.

The cascading mode is set incorrectly.
For example, the master device is set to Bridging, but
the slave device in question or any upstream device is
set to Port Forwarding.

In the Bridging mode, IPv4 (or IPv6) settings are disabled
on the slave device in question.

In the Port Forwarding mode, one of the following issues
occurs:

The master device's role is incorrectly set to 'Slave'.

The master device's downstream interface is
incorrectly set. For example, you use a USB cable to
connect the 1st slave device, but select the Ethernet
port as the downstream interface.

The role of the slave device in question or any
upstream device is set to 'Master' instead of 'Slave'.

The port number you added to the IP address is
incorrect. See
Port Number Syntax
(on page 191).

IPv4 (or IPv6) settings are disabled on the master
device.

The slave device in question or any upstream device is a
Raritan product that runs a "pre-3.3.10" firmware version
while the rest of the chain runs firmware version 3.3.10
or later.
