Alarm Port | Customer supplied cable | Alarm contact via a single shielded male HD15 connector. A single alarm port is present in SBC 5400 platform.
This software release does not support the Alarm Port. | Management Ports | CAT5e cable | Four copper Ethernet Ports which process Management traffic and perform protocol termination. | Locator |
|
| Module identifier indicator | Media Ports | Single mode or Multi mode fiber/copper CAT5e cable | Four copper SFP or fiber SFP ports for media and signaling traffic. | High Availability Ports | Single mode or Multi mode fiber/copper CAT5e cable (NON-CROSSOVER TYPE ONLY) | Two copper SFP or fiber SFP ports for redundancy synchronization traffic. The platform supports box level redundancy via communication paths provided by the external HA Ethernet ports. | Serial Port | Male DB9 connector | An RS-232 port used by BMC. | Field Service Port | Copper CAT5e cable | A single Field Service Port. | Power Input |
|
| Power Supply. The following are the descriptions of the power supply LED functions: - Off: No power input to the supply.
- Amber: Power supply fault.
- Blinking Amber: Main system power output fault.
- Blinking Green: Standby power to BMC is ON but main system power is not enabled.
- Solid Green: Both standby power to BMC and main system power are ON and OK.

| Warning |
|---|
|
Ribbon-provided SFP modules must be used to guarantee proper operation of the external ports. Failure to follow this recommendation may cause permanent damage to the system. |
| Info |
|---|
|
CAT6 cabling may be required in environments where there is unusually high Electro-Magnetic interference (EMI) from power lines, manufacturing equipment, or certain types of lighting. |
