Front Left WAN port 10baseT connection for WAN configured as a host
(i.e. straight lead to a hub)
Right 4 LAN ports 10baseT network hub for LAN
(i.e. straight lead to PCs)
Rear Left 9 way D Serial connection for factory test
May be used for other functions in future software
RFar right Power Connection for power, 9-24V DC centre positive

Lights

WAN Yellow Network activity on WAN
Greed Link active on WAN
Front ALERT Blinks briefly on power up
Blinks rapidly for blink filtering rules
Blinks slowly for flash alert status having been set
Solid on if profile set to affect ALERT LED
POWER On when power applied
Blinks off when reset (e.g. software upload, factory reset)
LAN Yellow Normally network activity - can be configured for other usage
Green Normal link active - can be configured for other usage

The 8 LAN hub LEDs can be configured to operate in the following modes :-
 
Yellow Green Note
Partition Link Link off if partitioned
Activity Link  
Partition
Blink for collision
Link
Blink for activity
 
Partition Link
Blink for activity
LEDs flash at reset
Partition Link
Blink for activity
 
Collision Link
Blink for partition
LEDs on for 4 seconds on reset
Bar graph of LAN activity All 8 LEDs make up bar graph
Cycling lights Same as when all lines unplugged

Note that if manually selected as cycling lights, then a time stamp reply packet is sent on the WAN every few seconds. This is a harmless packet and is used to allow multiple FireBricks to be synchronized if all connected to the same WAN hub. The LED selection screen shows a number of links (shown as dots) which allow the phase of the LEDs to be set allowing effects such as a "Mexican Wave" to be created. Note that this requires ICMP traffic frrom WAN to FireBrick from and to the FireBricks LAN stealth IP address to be allowed (create a filter).

Factory reset

To factory reset your FireBrick®, follow these steps :-
  1. Remove power and all network connections
  2. Connect a straight network lead (such as the one provided with the FireBrick®) from the WAN (left) to the right hand LAN port.
  3. Power on the FireBrick®
  4. Observe that the link light on the LAN port is lit and on the WAN port blinks rapidly.
  5. After a moment the red ALERT comes on.
  6. Remove the network cable with the power still connected
  7. The FireBrick® will reset (green and red LEDs go off for a moment), and then start as normal with cycling lights on the hub.
The factory reset is now complete - bear in mind that the FireBrick is now operating on the stealth IP as detailed in getting started.

DHCP mode

Normally, the FireBrick does not have DHCP enabled after factory reset. However, an alternative factory reset procedure will reset the FireBrick and enable DHCP. Simply connect the loop back cable to a different one of the WAN ports in the above procedure :-
 
Hub port Factory reset operation
0 (left) DHCP server on LAN and DHCP client on WAN
1 DHCP server on LAN
2 DHCP client on WAN
3 (right) Normal, non DHCP mode
