switches, enabling access to your storage volumes in complex configurations such as data-sharing or network zoning.

The docking connector at the rear of the controller board connects the controller module to the backplane board. A DDR RAM DIMM socket is strategically placed in an easily accessible location on the controller board for easy insertion of the DDR RAM DIMM module.

1.2.3 Controller Module Interfaces

All external interfaces that connect to external devices are located on the controller module rear panel shown below. The interfaces are listed below.

Figure 1-7: Controller Module Interfaces – 2-port version

ƒHost ports: Four (4) Gigabit Ethernet host ports (simulated and indicated as CH0 to CH3 in the diagram shown above) connect the SecurStor subsystem to the networked iSCSI initiators through RJ- 45 connectors.

ƒCOM port: The controller module comes with two (2) COM ports. The serial ports are used for local access to the firmware embedded configuration utility and the connection to a UPS device.

ƒLED indicators: Six (6) LED indicators illustrate the system statuses for system monitoring. Please see Chapter 3 for more information.

ƒEjection Levers: Two (2) ejection levers located on the sides of the controller ensure that the back-end connectors are properly seated in the module slot and properly mated with the backplane.

ƒManagement LAN Port: Another 10/100BaseT Ethernet port connects the subsystem to a management computer. Available management interfaces include: telnet, Java-based RAIDWatch manager, or the web-based manager invoked by an http console.

ƒRestore Default LED and button: The push button and LED are used to restore firmware defaults in cases when upgrading
