Switch Fabric Setup
The following describes the front panel and onboard features of the
Xedge Switch Fabric modules: XH, XS and XM. Indicators and jumpers
operate in the same manner except where noted.
Front Panel Indicators
All Xedge switch fabric modules have front panel TX and RX LEDs that
correspond to each slot controller interface. The XH, XS and XM have
LEDs for 16 interfaces (S0 - S15). The front panel LEDs on the XM and
can be set to one of three display modes by setting an onboard jumper.
•
FLT
Indicator
Illuminates red when a problem prevents the Switch Fabric from
functioning. Normally Off.
•
RUN
Indicator
Steady On while the Swtich Fabric is powered on and operating.
Normally On. (See Redundant Fabric, below)
•
TX
Indicator
Illuminates when data is sent from the associated slot controller to the
Switch Fabric.
•
RX
Indicator
Illuminates when data is received at the associated slot controller
from another controller in the switch.
Health Checks
Once every second, the Slot-0 Controller sends a health check request
cell to all active controllers in the switch via the Switch Fabric module.
Each active controller responds to the Slot-0 Controller with a health
check response cell via the Switch Fabric module.
This health check request/response sequence causes the
TX
and
RX
LEDs on the Switch Fabric module to blink once every second for each
active Slot Controller.
Redundant Switch Fabric
The XH or XM Switch Fabric modules can be installed as Main or
Standby fabric in a redundant system. When in-service, the
RUN
LED
is steady On. When out-of-service, the
RUN
LED flashes.

Switch Fabric Modules
Note
IMPORTANT! In a redundant system, always put the Switch Fabric in Standby mode (out-of-service) before
hot-swapping the module. The out-of-service Switch Fabric module can then be removed without interrupting
communication in the switch.
