12.1 LEDs
The following table explains the Ethernet Backplane
SwitchModule port status or activity LED blink sequences:
12.2 Ports
The Ethernet Backplane SwitchModule front panel ports
use crossover ports with RJ-45 connectors (see the figure
at right). The X that follows the port number indicates a
crossover port.
CoreBuilder 5000 10BASE-T modules use crossover ports.
This means that if you connect a 10BASE-T SwitchModule
port to another CoreBuilder 5000 10BASE-T module port,
you must use a crossover cable
