34 NX-Platform Hardware Installation and Safety
• The following conditions are displayed when the corresponding ports and segments are available, and
are hidden when they are unavailable:
• Segment configuration
• Network port configuration
• Network port health
• Network port throughput performance
• Traffic profile by network port
• A BIOM that is installed with the system powered on remains in bypass mode. This way the network
can continue to pass traffic while users configure the number of network ports and their speeds to meet
specific requirements. The BIOM must be taken out of bypass mode either administratively (using the
CLI or the LSM) or through a reboot.
• BIOMs that are installed with the power off are taken out of bypass mode automatically by the system
software.
• To change a BIOM from bypass mode to normal mode administratively:
• From the CLI, type:
high-availability zero-power no bypass-ips [-slot <slot number>]
• From the LSM menu, click System > High Availability and select Normal in the Zero-Power
HA External field.
For more information on making I/O module administrative changes through these interfaces, see the IPS
Command Line Interface Reference TOS Version 3.7 and the Local Security Manager User's Guide TOS Version 3.7.
