The DC3500 System Status table describes the conditions under which the
system status LED might be lit.
NIC activity Indicates whether there is any network activity.
• A green light indicates there is network activity.
• No light indicates there is no network activity.
System ID
Helps identify a system installed in a high-density rack with other similar
systems:
• A blue light indicates the ID button is pressed and a blue light is on at the rear
of the appliance.
• No light indicates the ID button is not pressed.

DC3500 System Status
CONDITION DESCRIPTION
Critical Any critical or non-recoverable threshold crossing associated with the following
events:
• temperature, voltage, or fan critical threshold crossing
• power subsystem failure
• system inability to power up due to incorrectly installed processors or processor
incompatibility
• critical event logging errors, including System Memory Uncorrectable ECC error
and fatal/uncorrectable bus errors, such as PCI SERR and PERR
Non-critical A non-critical condition is a threshold crossing associated with the following events:
• temperature, voltage, or fan non-critical threshold crossing
• chassis intrusion
• Set Fault Indication command from system BIOS; the BIOS may use the
command to indicate additional, non-critical status such as system memory or
CPU configuration changes
Degraded A degraded condition is associated with the following events:
• one or more processors are disabled by Fault Resilient Boot (FRB) or BIOS
• some system memory disabled or mapped out by BIOS
• one of the power supplies unplugged or not functional
TIP! If you observe a degraded condition indication, check your power supply
connections first. Power down the appliance, disconnect both power cords,
reconnect the power cords to re-seat them, and then restart the appliance.
W
ARNING! To power down safely, use the procedure in the Managing Devices
chapter in the Sourcefire 3D System User Guide, or the
shutdown -h now
command from the Defense Center’s shell.
