Onboard Memory
The boards are equipped with 32MB SDRAM memory (2 chips).

Onboard NAND Storage Device
The boards are equipped with one 64MB NAND nonvolatile memory chip.

CompactFlash Interface
You can use any CompactFlash Type I or II cards, as well as IBM/Hitachi Microdrive hard drives. Warning!
The RouterBOARD 153 series boards do not support hot insert of CompactFlash/Microdrive devices.

Extension Slots
MiniPCI Slot
MiniPCI Type IIIA slots has 3.3V only power signaling. The slots also accept MiniPCI Type IIIB standard cards.
Supplied power (shared between all the devices, including the CPU):
+3.3V: 4.0A

Input/Output Ports
LAN1 Port with PoE
This Fast Ethernet port is recognized as first LAN interface in most OSs. It is compatible with IEEE802.3af
Power over Ethernet standard (including power over datalines) and passive PoE (non-standard). The board
accepts non-standard voltage input in wide range: from 11 to 60 V DC.
The RouterBOARD 51 power injector may be used to power the board with up to 100m (330 ft) long Ethernet
cable. It is suggested to use 48V DC power for power over long cables because of better efficiency (less
power is lost in the cable itself and power supply is more efficient on higher voltage).
See Connector Index for pinout of the standard cable required for PoE. All cables made to EIA/TIA 568A/B
cable specifications will work correctly with PoE. Note that this port supports automatic cross/straight cable
correction (Auto MDI/X), so you can use either straight or cross-over cable for connecting to other network
devices.

Four LAN Ports without PoE
These Fast Ethernet ports are recognized as four independent LAN interfaces: LAN2 (at the corner of he
board) to LAN5 (near the PoE-enabled LAN1 connector). These ports are not intended to be used with PoE.
CAUTION! You will seriously damage the board by connecting PoE injector to these ports.

devices.

DB9 Serial Port
The RS232C standard male DB9 asynchronous serial port may be used for initial configuration, or for attaching
a modem or any other RS232 serial device. TxD (pin 3) of this port has -5V DC power when idle. RTS and DTR
signals are not connected. This implementation may not be considered to support full hardware flow-control
so software flow-control (XON/XOFF) should be used.
LEDs

Power LED
LED is on when the board is powered.

User LED
User LED may be programmed at user's option. It is lit by default when the board starts up, then it is turned
off when the bootloader runs kernel.

MiniPCI LEDs
3 pairs of MiniPCI LEDs are connected to MiniPCI slots (two LEDs per slot) according to standards.
