Hardware Guide

Memory and Storage Devices

Onboard Memory

The boards are equipped with 256 MB DDR2 SDRAM onboard memory.

Onboard NAND Storage Device

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

CompactFlash Slots

The board has one CompactFlash slot that supports Compact Flash Type I or II cards and True IDE
Microdrive storage devices. The CF slot is bootable. Warning! The RouterBOARD 800 series boards do not
support hot insert of CompactFlash/Microdrive devices.

Extension Slots

MiniPCI Slots

The board has four MiniPCI Type IIIA slots with 3.3V only power signaling. They also accept MiniPCI Type
IIIB standard cards. The board has been tested to operate with 5 Ubiquity SR series high power cards if
ambient temperature and adequate cooling is ensured.
Supplied power for the extension cards (excluding CPU and onboard Ethernet ports):
+3.3V: 7.5A typical

Daughterboard Connector

Additional Ethernet and/or MiniPCI slots may be connected to the board using the daughterboard
connectors. Two connectors are provided, the longer connector (J4) is routerboard-pci type, same as used
on RB600 and RB500 series devices. The shorter connector (J10) is routerboard-pcie type.

Input/Output Ports

LAN1 Port with PoE

This Gigabit Ethernet port is recognized as the first LAN interface. It is compatible with most Power over
Ethernet injectors. The board accepts voltage input from 38 to 56 V DC. It is suggested to use 48V for power
over long cables because of better efficiency (less power is lost in the cable itself and power supply is more
efficient).
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.

LAN2 Port

This Gigabit Ethernet port is recognized as the second LAN interface. This port does not support Power over
Ethernet.
All cables made to EIA/TIA 568A/B cable specifications will work correctly (see Connector Index for
pinout). 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.

LAN3 Port

This Gigabit Ethernet port is recognized as the third LAN interface. This port does not support Power over
Ethernet.
All cables made to EIA/TIA 568A/B cable specifications will work correctly (see Connector Index for
pinout). 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.
