Hardware Guide
Memory and Storage Devices
Onboard Memory
The RB450G equipped with 256 DDR SDRAM onboard memory, RB450 has 32MB DDR SDRAM onboard
memory.
Onboard NAND Storage Device
The boards are equipped with one built in NAND nonvolatile memory chip.
Extension Slots
MiniPCI Slots
The board has no miniPCI slots or other expansion abilities
Input/Output Ports
LAN1 Port with PoE
This Fast Ethernet port is recognized as the first LAN interface. It is compatible with passive (non-standard)
Power over Ethernet. The board accepts voltage input from 10 to 28 V DC. It is suggested to use the higher
voltage 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.
