This chapter contains the following sections:
The status LED on the front panel can display three colors: green, amber, red. (See “Front Panel Functions: Status LED, Power, Reset, NMI” for the location of the status LED.)
Table 9-1 lists the messages displayed by the status LED.
 | Note: Only the status LED of the master module of a two-module system displays messages. The status LED of a slave module is inactive. |
Table 9-1. Status LED Messages
LED Code | Meaning | Corrective Action |
|---|---|---|
Red briefly, then amber, | If you have just turned on the master power switch, this indicates the system controller is OK. | N/A |
Green, blinking | The system is booting. | N/A |
Green on solid | The system is on. | N/A |
Amber, blinking | Normal power-off sequence. | N/A |
Amber on solid | One of the fans has failed. | Replace the fan. See “If a Fan Fails” and “Replacing Fans”. |
Red, blinking (during power-off sequence) | A problem with the power supply was detected. | Replace the power supply. See “Replacing the Power Supply”. |
Red, blinking | The system temperature is too high, and the server is shutting down. | Check ambient air temperature. If the ambient air temperature is below 104˚ F (40˚ C),verify there is no debris or other obstruction preventing the flow of air into and through the system. Also, see “Checking the Fans” in Chapter 4 to verify that the fans are working. If the ambient air temperature is above 104˚ F (40˚ C), |
Red on solid | The system became too hot. The power supply failed during booting. | Check the system temperature: see “Using the AUX Port and Module System Controller Commands” in Chapter 4. Replace the power supply. See |
The Ethernet 10-Base-T/100-Base-TX port contains two integral LEDs: the transmit LED (green) and the packet detect LED (yellow). Figure 9-1 shows their locations.
The transmit LED (green) flashes whenever the Origin200 is transmitting data through the Ethernet port.
The packet detect LED (yellow) flashes whenever the server detects network traffic, even if the data detected is not destined for the server.
To test the power supply, press the button. If the green LED lights, the power supply is OK. If the green LED fails to light, there may be a problem with the power supply.
The power supply is not customer-replaceable. Contact Silicon Graphics or your local service provider for information about replacing the power supply.
The only regular maintenance that the Origin200 server requires is periodic cleaning to remove any dust accumulation. Because the server is designed to be operated in a typical office computing environment that is relatively dust-free, there are no air filters in the system. Therefore, depending upon the amount of dust in the operating environment, you may have to periodically vacuum parts of the server.
 | Caution: Do not use an ordinary vacuum cleaner to clean computer equipment. Use only a data vacuum cleaner. Data vacuum cleaners are specially designed to prevent damage to sensitive electronic components from electrostatic discharge (ESD). |
Use the following cleaning guidelines:
With the system running: Examine the exterior of the chassis for dust accumulation and remove it as necessary with a data vacuum. Air flows from the front of the system to the rear, so most dust accumulation should be at the front of the system. See “Air Flow and Fans”.
With the system off: Remove and examine the 3.5-inch drives, blanking plates, and drive slots for dust. Vacuum off any dust you find and replace the drives and blanking plates. See Chapter 8, “Installing and Configuring Peripherals,” for information on removing the drives and blanking plates.
With the system off: Remove and examine the peripheral carrier and the bay into which it slides. If dust has accumulated on the rear of the carrier, remove the access plate on the rear of the carrier and examine the interior of the carrier for dust. Vacuum off any dust you find and replace any components you removed. See Chapter 8, “Installing and Configuring Peripherals,” for information on removing the peripheral carrier.
With the system off: Open the system cover and chassis access door. Examine the interior of the system, starting with the front areas of the system and proceeding towards the rear. Vacuum off any visible dust, then replace the chassis access door and side panel. See Chapter 5, “Origin200 Cosmetic Features and Covers,” for information about removing the system cover and chassis access door. See Chapter 10, “Removing and Replacing Internal Components,” for information about removing the fans.
