Troubleshooting tools
The cable diagnostic tests only apply to Ethernet copper ports. Fiber ports cannot be tested.
You can initiate a test on multiple ports at the same time. After you test a cable with the TDR,
if the cable has a 10/100 MB/s link speed, the link is broken during the test and restored only
when the test is complete. TDR test does not affect the gigabit links.

System Logs

You can use the syslog messaging feature of the ERS 5600 Series products to manage event
messages. The ERS 5600 Series syslog software communicates with a server software
component named syslogd that resides on your management workstation.
The daemon syslogd is a software component that receives and locally logs, displays, prints,
or forwards messages that originate from sources that are internal and external to the
workstation. For example, syslogd software concurrently handles messages received from
applications running on the workstation, as well as messages received from an ERS 5600
Series device running in a network accessible to the workstation.

Auto Unit Replacement

With the Auto Unit Replacement (AUR) feature, you can replace a failed device in the stack if
AUR is enabled. You can replace a failed unit in a stack with a new unit, while retaining the
configuration of the previous unit. The stack power must be on during unit replacement.
If the model of the replaced unit is different from the previous unit, the unit is allowed to join
the stack. However, the configuration of the previous unit is not be replicated in the new unit.
AUR can be enabled or disabled from ACLI and EDM. By default, AUR is enabled.
