4.6. Extension Card Insertion
Please wait 30 seconds after powering off the equipment before inserting (or removing) an
extension card. This is to avoid possible damage to the Base Unit and Extension Card.
Remove the slot filler of the location where you want to insert the new card. To do this, press
on both ends of the cover, note that the hooks are out-centered like shown on the pictures.
Hooks to be pressed are off-centered – press while pulling upwards
This metal tag soldered on the PCB acts as mistake-proof security (mating stop in
housing)
Insert the Extension Card carefully and slide it down until the hooks are
clicking
. Make sure
the card is completely inserted.
DO NOT insist
if you feel some resistance when trying to
insert the card. It probably means you are trying to insert the card in a wrong slot. In such
case, check slot compatibility of the relevant Extension Card.
- Note -
Would an extension card be inadvertently forced in a wrong slot, the Base Unit will detect it
and will NOT complete its BOOT process. Therefore, the unit will not be accessible through its
LAN interface. The slot error is returned by the USR LED. (red ON 1sec, OFF 0.5 sec).
