Troubleshooting
Problem
LED status indicators for the PC Server 325
Resolving The Problem
NOTES:
1. During the power-on self test (POST), some of the LEDs come on briefly.
2. The amber LEDs might blink to show activity, and remain on to indicate that a problem condition exists.
 | Power-On Light | This green LED lights when you power-on the server by pressing the power switch, and when the server powers on in unattended mode. |
 | Unattended Power-On Light | This green LED lights when the server powers on in unattended mode. |
 | POST Activity Indicator | This amber LED lights while the power-on self test (POST) and the configuration utility programs are running. If this light remains illuminated, either a POST error has occurred, or the system microprocessor has stopped. |
 | SCSI Hard Drive In-Use Light | This amber LED lights when the server is accessing a SCSI device. If this light remains illuminated, this might indicate that either the SCSI bus or the system microprocessor has stopped. |
 | Primary Microprocessor In-Use Light | This amber LED blinks to indicate the activity of the primary microprocessor; it also comes on during POST. |
 | Optional (Secondary) Microprocessor In-Use Light | When an optional microprocessor is installed, this amber LED blinks to show the activity of the optional microprocessor; it also lights during POST. When installed, this optional microprocessor becomes the boot, or startup processor. |
 | Ethernet Transmit Light | This amber LED shows transmit activity on the network. |
 | Ethernet Receive Light | This amber LED shows receive activity on the network. |
 | Ethernet Link Status Light | This green LED shows an active link connection on the 10BASE-T interface. |
 | Security Light | When tamper-detection software is installed and enabled, this amber LED shows that a security hardware or software error occurred. |
