The following sections describe generic CHASSIS STATUS VIEW screen
fields and control procedures.
Mode
This field, located within parentheses next to the screen title, displays the
current screen mode.
Port Status
These fields consist of the columns of numbered ports located under the
device identifiers (MMAC24, STH24, et al). They display port-status
information and let you selectively enable and disable ports when in the
ADMINISTRATIVE mode.
Virtual Flexible Network Bus (VFNB)
Use this field (a quasi Network Bus), located at the top of each the
port-status column under the device identifier, to either bypass or activate
a module, or hub, when in the ADMINISTRATIVE mode.
Possible VFNB screen configurations for Enabled modules are described
as follows:
• Attached left (<----|): The module is connected via cabling to the next
module. For example, the MicroMMAC-T configured as module 1 is
connected to STH module 2
• Attached right (|---->): The STH 2, for example, is connected to the
MicroMMAC-T
• Attached left/right (<---->): The STH is connected to the STH or
MicroMMAC-T before it and the STH after it.
• Detached (|-----|): The MicroMMAC-T is not connected to an STH
module.
