channel cable. The two host ports in each controller are independent. They
are not connected in the controller module as they would be in a hub
configuration.
Ethernet port
The Ethernet port is for an RJ-45 10BASE-T or 100BASE-T Ethernet
connection. Use the Ethernet connection to directly manage storage
subsystems.
Expansion port
The expansion port is used to connect additional expansion units to the
RAID controllers. You first insert an SFP into the port and then connect a
fibre channel cable.
Note: There are no expansion ports on the DS4300 single-controller
storage subsystem (model 6LU and 6LX).
Serial port
The serial port is used by service personnel to perform diagnostic
operations on the RAID controller or controllers.
Tray ID switch
The Tray ID switch settings range from 0 through 7, and unique IDs ranging
from 00 through 77 can be set.
This switch is also referred to as enclosure IDs in other IBM DS4000
publications.
Note: For controller firmware version 05.33.xx.xx, both host and expansion ports
operate at 2 Gbps only. For controller firmware versions 05.4x.xx.xx and
higher, the host ports can operate at either 1 or 2 Gbps (the expansion port
speed is still locked at 2 Gbps only).
The latest DS4000 controller firmware and NVSRAM, the storage expansion
enclosure drive enclosure ESM firmware, and the fibre channel drive CRUs
firmware must be installed to ensure optimal functionality, manageability, and
reliability.
To enable support for the DS4300, you must ensure that your system's software
and firmware are at the levels shown in Table 5.
