RouterBOARD 200 Series User's Manual
Hardware Guide
Memory and Storage Devices
SoDIMM Memory
You can use any standard-sized SoDIMM PC100 or PC133 SDRAM memory modules. The PC66 modules,
which do not accept timing frequency more than 66MHz might not work reliably on RouterBOARD 200
series boards, so use of these modules is not recommended. The RouterBIOS automatically adjusts the
timing parameters of an inserted module to its maximal values.
There are some SoDIMM modules that violate the maximal hight dimension defined by the SoDIMM
standard. For example, some 512MB SDRAM modules are about two times higher than the standard
allows. These modules can not be used in the RouterBOARD 200 series computers.
CompactFlash Interface
You can use any CompactFlash Type I or II cards, as well as IBM/Hitachi Microdrive hard drives. JP2
jumper may be used to choose whether the inserted storage device will be ATA Master or Slave device.
Warning! The RouterBOARD 200 series boards do not support hot insert of
CompactFlash/Microdrive devices.
44 pin 2.5'' ATA Interface
You can use any ATA (IDE) hard drive with 44 pin interface. Generally, 2.5'' hard drives for notebooks
have this interface. Note that you can not connect a standard ATA drive to the RouterBOARD as all
standard ATA hard drives r12V, but the 44 pin connector only su5V and -5V.
Extension Slots
PCI Slot (RouterBOARD 230 only)
PCI v.2.1 slot with universal powering is compatible with all PCI expansion cards available on the market.
Supplied power:
+12V: 100mA (1.2W)
-12V: 100mA (1.2W)
5V:
3A (15W)
3.3V: 1.2A (4W)
MiniPCI Slot
MiniPCI Type IIIA slot has 3.3V and 5V power signaling with the same output power as PCI connector.
This slot also accepts MiniPCI Type IIIB standard cards.
Note
that only AR5212 and newer Atheros MAC chips are stable with RouterBOARD 230, if connected
with a multiport MiniPCI-to-PCI adapter (such as RouterBOARD 14 four-port MiniPCI-to-PCI adapter). This
note only applies to the RouterBOARD 200 platform with multiple Atheros-based cards.
Warning! Do not install PCI and MiniPCI adapters simultaneously. This configuration will not
work and may damage equipment.
PCMCIA Extension Slots (RouterBOARD 230 only)
The RouterBOARD 230 series has two independent PCMCIA/CardBUS slots controlled by Texas
Instruments PCI1250 chip with serialized IRQ (SERIRQ).
