### Power Supplies Shipped to Korea

For individually packaged spare power supplies (AC,A251A,H,12V,5740W) ordered under part number #300-2259 to be compliant with the South Korea KATS safety approval (K60950-1) labeling requirements, they must have Oracle manufacturing part number 7081582 or higher.

### Server Module Configurations

Before ordering or installing a server module for a specific modular system configuration, make sure to check the server module and chassis documentation to determine which server modules are supported with which chassis, as well as which other components are compatible with the server module.

### USB 3.0-Compatible Dongle Cable Now Available

If you want to connect USB 3.0 devices to the Sun Blade server modules and you have dongle cable 530-3936 (USB 2.0-only), you need to order dongle cable replacement part 7046680 (USB 2.0/3.0).

The enhanced USB dongle cable will support both USB 2.0 and USB 3.0 connectivity; however, the devices will run in 2.0 mode.

### Identifying Chassis Models

There are now four models of Sun Blade 6000 modular system available. Refer to the Sun Blade 6000 Modular System Service Manual for instructions on how to identify the chassis models that you have.

### New Chassis Available

Sun Blade 6000 chassis model 7105379 is now available for the Sun Blade 6000 modular system. The 7105379 chassis and associated components are functionally equivalent to A90-D and meet the requirements for EU Directive 2011/65/EU.

The 7105379 chassis contains the following updated components:

- Chassis monitoring module (CMM)

- Midplane assembly

If you are replacing any of these components, make sure to use the component that is supported for the chassis that you are using. The Sun Blade 6000 Modular System Service Manual contains detailed instructions on how to identify the chassis replacement components.

### New Power Supplies Available

Model A251A power supplies (PSUs) are now available for the A90-D and 7105379 model chassis. The A251A PSUs are functionally equivalent to A251 PSUs, and it can be used together with a A251 PSU in a chassis.

Note - If you need to replace an A251 power supply, you can replace it with either another A251 or an A251A. If you need to replace an A251A power supply, you must replace it with an A251A to maintain current EU safety and compliance requirements.

The following table shows the combination of power supplies and chassis that are compliant with current EU RoHS compliance and safety standards:

Chassis + PSU Combination | EU Directive 2011/65/EU | EN 60950 2nd Edition +A1
--- | --- | ---
A90D chassis + A251 PSU | No | No
A90D chassis + A251A PSU | No | Yes
7105379 chassis + A251 PSU | Yes | No
7105379 chassis + A251A PSU | Yes | Yes

### Available Modules

There are a number of server modules, storage modules, PCIe ExpressModules (PCIe EMs), and Network ExpressModules (NEMs) available for the Sun Blade 6000 modular system.

For information on server or storage modules that are available for the Sun Blade 6000 modular system, refer the links for each server or storage module at:

`http://www.oracle.com/us/products/servers-storage/servers/blades/index.html`

For information on PCIe EMs and NEMs that are available for the Sun Blade 6000 modular system, see:

`https://community.oracle.com/docs/DOC-915297`

You can also view documentation for these modules at:

`http://docs.oracle.com/`

### Mounting Systems in Square-Hole Racks

The current version of the Sun Blade 6000 Rack Alignment Template, 263-2755-03, contains instructions for mounting systems in a square-hole rack. The original version of the template (263-2755-01) does not contain these instructions.

If you wish to mount your system in a square-hole rack and the 263-2755-03 version of the rack alignment template document was not included with your rail kit, you can view this document on the Sun Blade 6000 modular system documentation page located at:

`http://www.oracle.com/pls/topic/lookup?ctx=sb6000`

Note - If you have an older rail kit (part number 371-2986-01) the brackets are all the same for front and back, so you can ignore references to front and rear brackets in the 263-2755-023 rack alignment template.

If you have trouble mounting the system with the 371-2986-01 rail kit, please contact your Oracle service representative about updating your rack kit.

### Rack Shipping Bracket for Sun Rack 1000

If you plan to ship your Sun Blade 6000 modular system installed in a rack, you will need to install the shipping support brackets that are included in the system rail kit.

Note - After the system has been shipped, remove the front shipping bracket support and reinstall the original screws into the rack before operating the system.

For instructions on installing the shipping brackets, refer to the Installing Shipping Brackets on a Sun Blade 6000 Modular System, 820-2388, posted on the Sun Blade 6000 modular system documentation site at:

`http://www.oracle.com/pls/topic/lookup?ctx=sb6000`

### Empty Slot Requires Filler

Do not operate the system with empty slots. Fillers are required for proper chassis airflow and cooling. Always insert a filler into an empty slot to reduce the possibility of module shut down.

Hardware Open Issues

This section describes hardware issues for the Sun Blade 6000 modular system.

- For Server Modules Running Linux, Load pciehp.ko and Unload acpiphp.ko Before Hot Plugging NEMs or PCIe EMs (7078324)

- Power Consumption Is Invalid in ILOM if PSU Side Is Under 25A (6438921)

- NEM LEDs (6713414)

### For Server Modules Running Linux, Load `pciehp.ko` and Unload `acpiphp.ko` Before Hot Plugging NEMs or PCIe EMs (7078324)

Do the following procedure to enable hot plug for any server module running a Linux OS before removing the module from the chassis.

1. Disable `acpiphp` using one of the following methods:

- Add the following to `/etc/modprobe.conf` or `/etc/modprobe.conf.local`:

`"install acpiphp /bin/true"`

- Issue the following command:

`#` `echo "install acpiphp /bin/true" >> /etc/modprobe.conf`

2. Do one of the following:

- To enable a single hot-plug action, do one of the following, depending on the version of Linux:

- For OEL/RHEL 5.x, issue the following commands:

`#` `echo modprobe pciehp >> /etc/rc.modules`

`#` `chmod +x /etc/rc.modules`

- For SLES, in `/etc/sysconfig/kernel`, change:

`MODULES_LOADED_ON_BOOT=""`

to

`MODULES_LOADED_ON_BOOT="``pciehp``"`

- For OL/RHEL 6.x, `pciehp` is built in, so you do not need to take any action.

- To enable the hot plug feature permanently, use the following command:

`#` `modprobe pciehp`

### Power Consumption Is Invalid in ILOM if PSU Side Is Under 25A (6438921)

This could result in missing information in the ILOM CLI and web interface. The following readings will occur if the power supply current is less than 25 Amps:

- If any side of an installed power supply unit (PSU) is drawing less than 25 Amps of current, the `ch.dc_watts` and `ch.ac_watts` IPMI sensors will show "disabled" when viewed with ipmitool.

- The IPMI sensors `ps` x`.dc_watts`, `ps` x`.ac_watts` and `ps` x`.peff` will also show "disabled"; where x is the PSU that has a side drawing less than 25 Amps.

- If any of the above conditions are true, such that chassis watts cannot be calculated, actual power cannot be calculated.

You will get the following output when you type the `show` command in CLI:

`show /CMM/powermgmt`

`actual_power = (none)`

##### Workaround

You can determine the amount of current a PSU side is drawing by reading the `/CH/PS` x`/S` y`/I_12V`; where x=0..1 (PSU) and y=0..1 (PSU side).

If using the CLI, you can determine the amount of current a PSU is drawing by typing:

`show /CH/PS` x`/S` y`/I_12V`

Where x= 0..1 (PSU) and y = 0..1 (PSU side).

### NEM LEDs (6713414)

The following tables show LED behavior for 10/100/1000 MB Ethernet LEDs for Sun Blade 6000 network express modules (NEMs). The LED color can be different, depending on the server module that is using the Ethernet port.

The LED speeds shown in the table are defined below:

- Standby blink--The system is functioning at a minimal level and is ready to resume full function. Defined as a repeating sequence consisting of 0.1 second On followed by 2.9 seconds Off.

- Blink--Transitory or new activity represented by the colored indicator is taking place. Defined as 1Hz @50% duty cycle.

| 10/100 MB (RJ45 Connector) | 1 GbE (RJ45 Connector)
--- | --- | ---
Server Module | Left Activity LED | Right Link LED | Left Activity LED | Right Link LED
X6220 | Green blink | Amber standby | Green blink | Green standby
X6240 | Green blink | Amber standby | Green blink | Green standby
