The management port supports Ethernet connections via Telnet. The IP address may be assigned automatically using a
DHCP, BOOTP or RARP server. The IP address may also be statically set using the ‘ipconfig’ command from the serial
port.
The serial connection on the management port may optionally be used to communicate with the RAM-SAN. The cable
provided with the RAM-SAN connects to another serial port using the following settings:
8 data bits No parity 1 stop bit 9600 baud No flow control
2.5 Power-Up
The power cords are connected to the rear of the RAM-SAN chassis. The RAM-SAN is wired for 110/220 volt AC. A fully
loaded RAM-SAN will draw less than 525 Watts. Turn on all 3 power modules before switching on the master power
switch. This will ensure that none of the power modules are overloaded. You should see one neon bulb turn on as each
module’s power switch is activated. When the master power switch is turned on, a red LED should light up on each of the
three power supplies signaling OK DC power. On power-up, the system will boot up, run a few quick processor tests, and
initialize all of the internal memory. If you have a serial connection to the management port, you should see the following on
the display during power-up:
** Starting up TREX+ **
** Creating low-level tasks.......done
** Creating monitor task..........done
** Creating ethernet task.........done
** Creating DEVMAN tasks..........done

At this stage the RAM-SAN is ready for use.
2.6 System Tests
The management port is capable of running diagnostics on the internal memory of the RAM-SAN. This should be the first
test that is run after unpacking the system. By pressing enter, a prompt should appear on the serial connection. At this point,
type ‘testmem’. You may get a message that memory is still being initialized. If this happens, wait a few seconds before
trying this command again.
This diagnostics generates and checks data patterns in the memory system. If any error is found, a message describing the
error will be displayed. See Chapter 5 for a complete description of this command.
2.7 Connecting the Fibre Channel Ports
After checking the memory system, the Fibre Channel port may be connected to switches or other host bus adapters (HBAs).
The ports should automatically recognize another port is connected and be ready for use. See Appendix A for a device
compatibility listing. To verify a connection, use the ‘status’ command.
