BAM8270 Manual
As the POST (Power On Self-Test) routines are performed during boot-up, test codes are displayed on
Port 80 POST Code LEDs 0, 1, 2, 3, 4, 5, 6 and 7. These LEDs are located near the rear USB ports on the
motherboard.
Note
: Access to Insyde Software POST codes is contingent upon a signed non-disclosure agreement
(NDA) between Trenton Systems, Insyde Software, and all other parties requesting access.
P45 ETHERNET LEDS
The I/O bracket houses the two RJ-45 network connectors for Ethernet LAN1, LAN2. Each LAN interface
connector has two LEDs that indicate activity status and Ethernet connection speed. Listed below are
the possible LED conditions and status indications for each LAN connector:
LED/CONNECTOR
DESCRIPTION
Activity LED
This LED identifies the validity of a link on the specific interface. This is the
upper LED on the LAN connector (i.e., toward the upper memory sockets).
Off
No valid link exists on this interface.
On (flashing)
Indicates network transmit or receive activity.
On (solid)
Indicates a valid link with no transmit or receive activity.
Speed LED
This multi-color LED identifies the connection speed of the SHB’s P4A
(LAN2) and P4B (LAN1) Ethernet interfaces. These are the lower LEDs on
the dual LAN connector (i.e., toward the edge connectors).
Green
Indicates a valid link at 1000 Mb/s
Amber
Indicates a valid link at 100 Mb/s.
Off
Indicates a valid link at 10 Mb/s.
RJ-45 Network Connectors
The RJ-45 network connector requires a Connector category 5 (CAT5)
unshielded twisted-pair (UTP) 2-pair cable for a 100-Mb/s network
connection or a category 3 (CAT3) or higher UTP 2-pair cable for a 10-
Mb/s network connection. A category 5e (CAT5e) or higher UTP 2-pair
cable is recommended for a 1000-Mb/s (Gigabit) network connection.
