monitor, see Chapter 5.

- 4 -

Basic Features

This section describes the basic features of the EM card.

Management Feature

The management features of the EM card are as follows:

Power Management

The EM card manages DC output of power unit(s) in the Blade Enclosure. When AC power is supplied to the Blade Enclosure, the EM card starts operating. If two or more power units are installed in the Blade Enclosure and they are working normally, the EM card turns on the DC output of two of them.

NOTE: For the third and subsequent power units, DC output is turned

on/off as needed.

The EM card manages the power consumption of the entire system. The maximum power consumption of the entire system varies depending on the power capacity

supplied to the system and the configuration of power units (including the number and type of units).

The EM card manages the power consumption of each of the modules of the system so that its maximum power consumption is maintained within a certain value (referred to as "ceiling control").

One of the following three upper limit values is used for ceiling control: (A) Upper limit determined by the type and number of power supply units and the input voltage. (B) If a UPS is managed by the EM card, the EM card calculates the upper limit based on the type

of UPS connected.

UPS Manager. See "Configuration File" in Chapter 3 and "Configuration" in Chapter 4 for details.

The EM card uses the lowest value among (A), (B), and (C) as the upper limit value and performs ceiling control of system power consumption.

You can select a power redundancy mode (N+N redundant or N+1 redundant) and a power control policy (CPU performance, "maintain redundancy," or "recover redundancy") for the power management policies of the EM card.

- 5 -

 There are two power redundancy modes, N+N redundant and N+1 redundant.

– In the N+N redundant mode, each power unit is divided into two groups to configure

the redundant power supply system. If a power supply in a group fails, the power of the other group can maintain system operation.

– In the N+1 redundant mode, power units are not grouped but each power unit is

controlled individually. Using a power supply in addition to the number of power units required for normal system operation enables power system redundancy.

 The power control policy includes three modes, CPU performance, "maintain

redundancy," and "recover redundancy." – The CPU performance mode makes the EM card prioritize performance of CPU blades.

In this mode, if the EM card cannot accept a new power request from a CPU blade while maintaining power redundancy, the EM card releases the power redundant configuration and permits the new power request from the CPU blade. (If a power unit fails during operation under the release of the power redundant configuration, then the system may be forcibly shut down.)

– The "maintain redundancy" mode makes the EM card accept a new power request from

a CPU bladeonly if the power redundancy can be maintained. If the EM card cannot accept a new power request from a CPU blade while maintaining power redundancy, the EM card denies the request. In the "maintain redundancy" mode, no emergency measures are taken if the power redundancy is lost due to a failure of a power unit. (When a power unit fails with no power redundancy status, the system may be forcibly shut down.)

– The "recover redundancy" mode makes the EM card accept a new power request from

a CPU blade while maintaining power redundancy by limiting the performance of CPU blades to reduce the power consumption in the event of a power unit failure. (Depending on the operation of CPU blades, the EM card may not be able to reduce the power consumption to allow the power redundancy to be recovered.)

When a switch module inserted into a switch module slot issues a power-on request, the EM card checks the power consumption of the switch module and turns it on if it is within the maximum power consumption management described above.

When a CPU blade inserted into a CPU blade slot requests power, the EM card permits it if the power consumption is possible within the maximum power consumption management described above.

NOTE: When a CPU blade issues a power-on request to the EM card,

the request is denied if the EM card determines there is insufficient power due to an event such as a power shortage.

- 6 -

UPS Management

The EM card monitors the status of UPS supplying power to the Blade Enclosure. In addition, the EM card shuts down CPU blades if AC power to the UPS is interrupted.

NOTES:

 Check that the UPS has enough capacity to supply the power

required for the entire system. The EM card calculates the maximum capacity of power supplied by the UPS to reflect the value in the maximum power consumption management described above. If the UPS has a low power supply capacity, some CPU blades may not be turned on.

 When using Windows 2003 Server, "Logging on to the system is not

required to shut down the system" should be enabled in the Security Policy tab.

 The EM card automatically detects the following UPS’s:

For 200 VAC: 5000VA UPS [N8142-24A] and 8000VA-UPS [N8142-25] For 100 VAC: 3000VA-UPS [N8142-11B] and 1500VA-UPS [N8142-23A]

 As described above, in the event that power to the UPS is

interrupted, CPU blades may be shut down automatically. However, after power to the UPS is restored, the CPU blades will not start automatically. You need to power on the CPU blades manually.

Cooling Fan Management

When the CPU blade is powered on, the necessary amount of cooling air changes according to the temperature. The EM card determines the optimal rotation speed of the fan according to the number of installed fan units.

NOTE: Depending on the number of installed fan units and CPU

blades and their installation locations, when the EM card determines that the cooling capacity is insufficient, it may not permit a CPU blade to power-on. In this case, check that the fan units and CPU blades are properly installed.

- 7 -

Interface Management between CPU Blade and Switch Module

If the CPU blade is incorrectly connected to the switch module, it will be damaged. To prevent this, the EM card checks the interface connection between them. If the interface connection is not correct, the EM card suppresses the power-on of the relevant CPU blade and switch module or disables the connection port.

NOTE: For more information on the connection between the CPU

blade and switch module in the Blade Enclosure, refer to the User's Guide of the switch module.

Chassis Information Management

The EM card manages the names of the rack, Blade Enclosure, CPU blades, and switch modules. Except for CPU blade names, they are specified in a configuration file.

NOTE: The CPU blade name can be obtained from the CPU blade.

- 8 -

Blade Enclosure Inter Connect

If more than one Blade Enclosure (SIGMABLADE-M) is mounted in a single rack, connect a LAN cable (straight) to the LOWER port of the topmost Blade Enclosure and the UPPER port of the Blade Enclosure installed beneath it to allow the EM cards of the Blade Enclosures to share the rack name and its unique ID.

The EM cards can read the status information of the Blade Enclosures and display the information on the Web console.

The Rack Information screen on the Web console has a link for each connected Blade Enclosure. When the same user name and password are set for the Web consoles, you can automatically log in

to any Web console through the link to the Web console. See Chaper 4 for details of the Web console.

IMPORTANT:

 To use the Blade Enclosure inter connect, EM card N8405-019A

must be installed.

 For the Blade Enclosure inter connect, use LAN cables (straight) as

short as possible. LAN cables of three meters or less are recommended.

 Do not connect a LAN cable to the UPPER port of the topmost

Blade Enclosure and the LOWER port of the Blade Enclosure installed beneath it.

NOTES:

 Check that LAN cables are connected correctly. Each of the EM

cards recognizes the positional relationship among the Blade Enclosures in the rack depending on the cable connections to the UPPER and LOWER ports on the Blade Enclosures. Incorrect cable connections prevent the EM cards from recognizing the positional relationship among the Blade Enclosures properly.

 Up to six Blade Enclosures can use the Blade Enclosure inter

connect.

Bridge Function

The EM card bridges packets from the EM1/EM2 port at the rear of the Blade Enclosure to the internal network. It enables network communication between the management unit of the CPU blades and switch modules in the Blade Enclosure (e.g., EXPRESSSCOPE Engine) and external devices.

NOTE: When bridging, the EM card executes port filtering to prevent

unnecessary packets from flowing to the network. The port number 49623 is used exclusively by the EM card and cannot be used for any other purpose.

SNMP Agent

SNMP is a protocol used to communicate management data among network devices. The administrator of the EM card can use SNMP to monitor the operating status of the EM card and

the blade system (Blade Enclosure, fan units, or power units) which the EM card manages. Registering community name and SNMP trap message destination are specified in a configuration

file.

Duplex EM

Installing two EM cards in the EM1 and EM2 slots enables the duplexed configuration. In the duplexed configuration, one of the EM cards is an active EM, and as the other is a standby EM card. The cards are connected with an internal serial interface to transmit/receive information synchronously.

When an active EM fails or when the switchover command is executed, it is changed to a standby EM after the system is rebooted. The previous standby EM then becomes the active EM.

IMPORTANT:

 In the duplexed configuration, the firmware revision of the EM

cards should be the same.

 To use the Blade Enclosure inter connect in the duplexed

configuration, EM card N8405-019A must be installed. If the Blade Enclosure inter connect is not used in the duplexed configuration, both N8405-019 and N8405-019A can be used in the Blade Enclosures. The Blade Enclosure inter connect can be used without the duplexed configuration.

NOTE: When the switchover command is executed, the bridge feature

is temporarily stopped, and the management LAN interface may be temporarily disconnected.
