System status Power Fault Temp • Flashing-the Ethernet port is receiving data. • Flashing rapidly-the traffic level is high. • On-the port is connected to an operational Ethernet. • Off-SFP is not installed in the port. • On (green)-Normal port operational status when an SFP is installed and a link has been established. • On (yellow)-port has an SFP installed but a link has not been established. • Flashing (green)-activity. Data is being transferred between the port and device. • On-the switch is plugged in and the internal power supply is functional. • On-an event has occurred that meets or exceeds the current Fault threshold setting. The default Fault threshold setting is critical. The switch will continue to operate. Switch functionality may be impaired depending on the event that triggered the Fault condition. Regardless of the cause, the switch requires immediate attention. • On-the internal temperature has exceeded acceptable levels. The switch will continue to operate. Switch functionality may be impaired depending on the event that triggered the Temp condition. Regardless of the cause, the switch requires immediate attention. Power-on self test (POST) When the switch powers on, it runs Power-On Self-Test (POST) diagnostics to verify the fundamental integrity of the switch ports. All switch LEDs turn on (LEDs illuminate). Then, excluding the Ethernet Link and Power LEDs, the LEDs turn off (LEDs extinguish). Once the switch is operational, the LEDs display current status. See Figure 17 (page 45). 30-10010-02 loop switch The 30-10010-02 loop switch contains both system indicators and port indicators. The system indicators indicate the status of the switch, and the port indicators provide status of a specific port. Figure 18 (page 46) shows the 30-10010-02 loop switch with the system and port indicators. The Fibre Channel loop switch acts as a central point of interconnection and establishes a fault-tolerant physical loop topology between the controllers and the disk enclosures.

•
Flashing—the Ethernet port is receiving data.
•
Flashing rapidly—the traffic level is high.
1. Ethernet activity
•
On—the port is connected to an operational Ethernet.
2. Ethernet link
•
Off—SFP is not installed in the port.
•
On (green)—Normal port operational status when an SFP is installed and a link has been
established.
•
On (yellow)—port has an SFP installed but a link has not been established.
•
Flashing (green)—activity. Data is being transferred between the port and device.
3. Port status
4. System status
•
On—the switch is plugged in and the internal power supply is functional.
Power
•
On—an event has occurred that meets or exceeds the current Fault threshold setting. The
default Fault threshold setting is critical. The switch will continue to operate. Switch
functionality may be impaired depending on the event that triggered the Fault condition.
Regardless of the cause, the switch requires immediate attention.
Fault
•
On—the internal temperature has exceeded acceptable levels. The switch will continue to
operate. Switch functionality may be impaired depending on the event that triggered the
Temp condition. Regardless of the cause, the switch requires immediate attention.

Power-on self test (POST)
When the switch powers on, it runs Power-On Self-Test (POST) diagnostics to verify the fundamental
integrity of the switch ports. All switch LEDs turn on (LEDs illuminate). Then, excluding the Ethernet
Link and Power LEDs, the LEDs turn off (LEDs extinguish). Once the switch is operational, the LEDs
display current status. See

30-10010-02 loop switch
The 30-10010-02 loop switch contains both system indicators and port indicators. The system
indicators indicate the status of the switch, and the port indicators provide status of a specific port.
Figure 18 (page 46)
shows the 30-10010-02 loop switch with the system and port indicators.
The Fibre Channel loop switch acts as a central point of interconnection and establishes a
fault-tolerant physical loop topology between the controllers and the disk enclosures.
