If the CMU copper data port is connected to a network, check the following:
• The associated network equipment (workstation, PC, router, switch etc.) is powered up
and operating correctly.
• The Ethernet port in the associated equipment is enabled.
• The Ethernet cable between the CMU and the network equipment is connected and is
not damaged. If possible, substitute a known good Ethernet cable.
• The Ethernet ports have compatible auto negotiation and duplex settings as described
in Configuring the IP interface and management mode on page 6-10.
If the CMU Data port is connected directly to a PC, check the following:
• The Ethernet port in the PC is enabled.
• The Ethernet cable between the CMU and the PC is connected and is not damaged. If
possible, substitute a known good Ethernet cable.
• The Ethernet ports have compatible auto negotiation and duplex settings as described
in Configuring the IP interface and management mode on page 6-10.
If these steps fail to resolve the problem, continue at Using recovery mode on page 7-71,
selecting the option to reset IP and Ethernet configuration.
