Note on the Use of 200V Power Supply

For servers that have the B-type plug, confirm that a 15A overcurrent protection device is available outside the server. If one is not available, prepare an external 15A overcurrent protection that can be achieved by means of no-fuse breakers (NFBs) or fuses. The B-type plug refers to plugs other than grounding-type ones with two parallel blades, such as the NEMA L6-30, L6-20, L6-15, and L5-15.

Connecting an SAS Device With Multiple SAS Targets to Onboard External SAS Interface Not Supported

It is not supported to connect an SAS device containing multiple SAS targets to the onboard external SAS interface. Instead, use a Sun StorageTek Host Bus Adaptor (SG-XPCIE8SAS-E-Z). [CR 6765239]

Booting Multiple Systems From a Single J4200 JBOD Storage Array

Sun Storage J4200 SAS JBOD arrays have six general-purpose SAS connectors. With FW version 3A32 or higher, each of them can be connected to separate SAS initiators, therefore up to six systems can be connected to the array. Each system can use a different disk on the array as its boot device. J4200 arrays have 12 disks, so each boot device can be mirrored for higher reliability. J4200 SAS arrays can be configured into multiple zones to provide a more secure environment.

Notes on the Use of USB Memory

To execute the dumpconfig(8), restoreconfig(8) or snapshot(8) command, if you specify USB memory as the destination to store data, prepare the USB memory as a medium in advance.

The data stored will include the information about the system. To use USB memory, you need to pay attention to the management of the USB memory in which the data stored, from the data security viewpoint.

We do not provide guarantees on the proper operation and connectivity to the XSCF of every USB memory currently manufactured on the market. Depending on the USB memory in use, defects such as the XSCF firmware error or reset may occur. In case such defects occurred, stop the use of USB memory immediately.

To connect the USB memory to the USB port for the XSCF, connect the USB memory directly to the USB port. If connected via the USB hub or USB extension, it might cause errors.

Hardware Documentation Updates

This section contains late-breaking hardware information and corrections that became known after the documentation set was published.

TABLE 2-1 lists known documentation updates.

TABLE 2-1 Hardware Documentation Updates
Title	Page Number	Update
SPARC Enterprise M3000 Server Overview Guide	1-25	1.4.6.2 "SAS Port" The article on "SAS Port" will be replaced by the following. The SAS port connects the server to an external device, such as a tape drive, which has an SAS interface. For information on which devices can be connected, contact a service engineer. Note that the transfer rate of this port is up to 600MB/s (3Gbps x 2wide).
