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.
(C) Upper limit specified for input voltage regardless of the configuration of power units or use of
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.
- 9 -
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.

Login and Basic Operations
This section describes how to input a command, login, logout, and change the password.
Command Input
The command input is described below.
About Command
The EM card accepts commands sent from the CLI (Command Line Interface). When the CLI is
ready for command input, it displays a "$" sign as a prompt at the beginning of the line.
A command should be entered following the command prompt displayed on the screen. For
commands that need parameters, those parameters should be separated with spaces.
Commands should be entered in 1-byte (half-size) alphanumeric and symbol or their combination.
Up to 255 characters can be accepted for one command.
Error Messages during Command Input
When the command is incorrect, an error message appears.
- 21 -
Login / Logout
This section describes how to log in or log out of the EM card.
Login
When the EM card is accessed from the local console connected to the serial port or from the
computer connected to the management port, login authentication is executed.
Enter the login user name and login password.
The login user name is "admin". The shipping default password is "admin".
This section describes the setup steps necessary to use the EM card.
Basic Setup
This section describes the setting of date, time, and IP address for remote control.
Setting Date and Time
The EM card incorporates a calendar clock equipped with a backup battery.
Use the "setdate" command to set the current date and time.
Shown below is an example of setting the date and time to 9:10:11 am on July 8, 2006:
To check the date and time, use the "setdate" command with no argument.
Shown below is an example showing the current date and time is 9:10:20 on July 8, 2006:
To access the EM card from the remote console via Telnet, you must specify an IP address. The
default IP address is 192.168.1.8/24.
NOTE: This setting is effective for the EM1/EM2 ports on the rear of
the Blade Enclosure.
To change the default IP address, access the EM card from the remote console by using the default
IP address, or from the local console connected to the serial port.
Specify an IP address in the configuration file.
NOTE: You can also use [SIGMABLADE Monitor] menu described
in Chapter 5 to specify an IP address. In addition, you can use the Web
console described in Chapter 4 to change an IP address. In either case,
the new data is saved in the configuration file.
Use the "showemip" command to confirm the setting.
When a character string is used for <set-value>, the character string must be enclosed with double
quotation marks.
NOTE: A line containing only space characters is ignored.
IP Address of EM Card
The two EM cards installed in the Blade Enclosure use four IP addresses in total. These addresses
are classified into two types, "Fixed IP" is determined by the installation slot of the EM card, and
"Floating IP" is used by the active EM card regardless of the installation slot.
The last bit of "Fixed IP" corresponds to the installation slot.
The last bit of "Floating IP" is defined as "0" for the active EM card and "1" for the standby EM
card.
- 25 -
NOTE: The IP address of the EM card is classified by the last two bits
as shown below:
00b: "Floating IP" that an active EM uses.
01b: "Floating IP" that a standby EM uses.
10b: "Fixed IP" of EM card installed in slot EM1.
11b: "Fixed IP" of EM card installed in slot EM2.
Default settings are shown below:
"Floating IP" of active EM: 192.168.1.8/24
"Floating IP" of standby EM: 192.168.1.9/24
"Fixed IP" of EM card in slot EM1: 192.168.1.10/24
"Fixed IP" of EM card in slot EM2: 192.168.1.11/24
Write the configuration file in the format as shown below:
The IP addresses of management I/F of CPU blades and switch modules are automatically assigned
by the DHCP server of the EM card. Specify the base address and default gateway of the IP
addresses to be assigned.
Bases addresses are assigned as shown below:
– CPU blade installed in slot #1: Base address +0
– CPU blade installed in slot #2: Base address +1
– CPU blade installed in slot #3: Base address +2
:
– CPU blade installed in slot #8: Base address +7
– Switch module installed in slot #1: Base address +8
– Switch module installed in slot #2: Base address +9
– Switch module installed in slot #3: Base address +10
– Switch module installed in slot #4: Base address +11
– Switch module installed in slot #5: Base address +12
– Switch module installed in slot #6: Base address +13
Write the configuration file in the format as shown below:
<IP Address>: Base IP address
<Default Gateway>: Default gateway
The above addresses must be specified with decimal numbers and periods such as
XXX.XXX.XXX.XXX (XXX: between 0 and 255).
NOTES:
Check that the "base address" is set so that its subnet mask is the
same as that of the EM card.
Check that the value "Base address + 23" is 254 or smaller.
"CFG_DHCP_ENABLE = <enable | disable>" indicates whether the DHCP server of the EM card is
enabled (1) or disabled (0). The default setting is "1" (enable). Generally, you do not need to change
the default.
- 27 -
IMPORTANT:
The IP addresses for the management interface of the CPU
blade/switch module are assigned based on the "base address." The
"base address + 14" to "base address + 23" are used by the system.
The consecutive addresses ranging from the "base address" to "base
address + 23" must not be assigned to other devices.
For UPS management, the "base address + 14" to "base address +
17" are assigned. The UPS to which a specific IP address is assigned
cannot be defined. The consecutive addresses ranging from the
"base address" to "base address + 23" must not be assigned to other
devices.
The IP addresses assigned to the switch module are valid for 24
hours at the longest (depending on the switch module). If you
reassign the IP address for the switch module, the change may not
be reflected immediately. In this case, cycle the AC power to restart
the system or remove then insert the switch module.
For the CPU blade, the IP addresses are automatically reassigned
when the setting is changed.
The IP addresses assigned to the UPS through DHCP are valid until
the SNMP card installed on the UPS is reset. If you want to assign a
new IP address to the UPS, you must reset the SNMP card.
Specify the name of the Blade Enclosure in which the EM card is installed, and the rack name on
which the Blade Enclosure is installed. In addition, specify the name of the switch module to be
installed in the same Blade Enclosure in which the relevant EM card is installed. Specify the names
with up to 31 ASCII characters.
NOTE: If no rack name or Blade Enclosure name is specified, the
value stored in the Blade Enclosure is used instead. When you specify
the Blade Enclosure name and the rack name, those names are stored in
the Blade Enclosure.
If no switch module name is specified, the value stored in the switch
module is used instead. When you specify the switch module name, that
name is stored in the switch module.
Write the configuration file in the format as shown below:
<SWM-1 Name>: Name of the switch module installed in slot number 1
<SWM-2 Name>: Name of the switch module installed in slot number 2
<SWM-3 Name>: Name of the switch module installed in slot number 3
<SWM-4 Name>: Name of the switch module installed in slot number 4
<SWM-5 Name>: Name of the switch module installed in slot number 5
<SWM-6 Name>: Name of the switch module installed in slot number 6
NOTE: NEC ESMPRO Manager accepts single-byte characters
including alphanumerics, period, hyphen, and underscore. Accordingly,
it is recommended to use these characters when specifying a name.
- 30 -
SNMP
Community Name
Specify a community name used for communication with the EM card via SNMP and SNMP trap
transmitted by the EM card. Up to 32 ASCII characters can be used. The default name is "public."
Write the configuration file in the format as shown below:
----------------------------------------------------------------[RW_SNMP_SECTION]
CFG_GET_REQUEST_COMMUNITY = "<Get-request Community Name>"
CFG_SET_REQUEST_COMMUNITY = "<Set-request Community Name>"
CFG_TRAP_REQUEST_COMMUNITY = "<Trap-request Community Name>"
<Get-request Community Name>: Community name of SNMP Get Request
<Set-request Community Name>: Community name of SNMP Set Request
<Trap-request Community Name>: Community name of SNMP Trap Request
NOTE: The trap message will be sent to all the specified destinations.
Acknowledge Waiting Time and Retry Count of SNMP Trap
If NEC ESMPRO Manager receives a SNMP trap message, an acknowledge message is issued from
NEC ESMPRO Manager. If an acknowledge message is not received within the specified time, the
same trap is retransmitted. Specify the time to wait for the acknowledge message in seconds and the
number of retries.
Write the configuration file in the format as shown below:
<Ack Waiting Time>: Acknowledge waiting time of SNMP trap (unit: second)
<Max Retry-Number>: Maximum retry number of SNMP trap
- 32 -
Setting Power Management
Specify the power management settings of the EM card.
Power Redundancy Mode
Specify the power redundancy mode of the EM card. The default setting is the [N+N redundant
mode].
NOTES:
In N+N redundant mode, each power supply unit is divided into two
groups to configure the redundant power supply system. AC line
group 1 is composed of PSU1 and PSU2, and AC line group 2 is
composed of PSU3 and PSU4.
In N+1 redundant mode, each power supply unit is controlled
individually. Installing one power supply unit in addition to the
required number of power units enables the redundant power supply
system.
- 33 -
Power Control Policy
Specify the power control policy fof the EM card. The power control policy includes three modes:
CPU performance, "maintain redundancy," and "recover redundancy." The default setting is the
[CPU performance mode].
NOTE: 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.)
- 34 -
Write the configuration file in the format as shown below:
NOTE: Check that "2" or "3" is specified as the power redundancy
mode. If not, the default setting (N+N redundant mode) is used. Check
that "2," "3," or "4" is specified as the power contol policy. If not, the
default setting (CPU performance mode) is used.
IMPORTANT:
The N8405-023 PSU works only in [N+N redundant mode]. Be sure
to specify [N+N redundant mode] before using the N8405-023 PSU.
Specify "maintain redundancy" or "recover redundancy" mode for
the N8405-039 PSU. Under this condition, "N+1 redundant mode"
is recommended.
- 35 -
Apply
Use the "apply" command to apply the settings in the configuration file to the EM card.
If two EM cards are installed, executing the "apply" command from the active EM card applies the
configuration file to the standby EM card also.
IMPORTANT: Executing the "apply" command reboots the EM card.
If two EM cards are installed, both cards are rebooted. While rebooting,
the bridge and SNMP functions are stopped. Accordingly, the
connection via the management LAN of CPU blades and switch
modules is temporarily disconnected. In addition, system monitoring by
NEC ESMPRO Manager is temporarily disabled. If a timeout error
occurs, reconnect after the active EM card has rebooted.
NOTES:
When two EM cards are installed, check if the standby EM card
works normally. If the standby EM card is activated or faulty, the
"apply" command cannot be executed.
Wait for a moment until the standby EM card becomes ready.
If the standby EM card is faulty, remove it before executing the
"apply" command.
It is recommended to make a backup copy of the configuration data
of the EM card.
For information on the backup/restore procedure, see
"Backup/Restore of Configuration File" described later.

Description
CFG_USE_UPS_MNG
Specify whether UPS management by the EM card is enabled or not.
1: TRUE (enable)
0: FALSE (disable)
The default setting is "0" (disable).
CFG_NUM_OF_UPSES
Specify the number of UPS’s managed by the EM card. The default setting is "0."
CFG_NUM_OF_POWERSUPPLIES
Specify the number of power units (PSU’s) installed in the Blade Enclosure.
The default setting is "1."
CFG_MIN_NUM_OF_UPSES
Specify the minimum number of UPS’s required to maintain system operation. When
power to a UPS is interrupted, CPU blades can be shut down. If the number of available
UPS’s falls below the specified minimum, CPU blades are shut down.
Value "0" does not shut down CPU blades.
The default setting is "0" (no shutdown of CPU blades).
- 55 -
CFG_UPS_INPUT_LOST_DELAY
Specify the time in seconds the EM card waits until it determines that power to the UPS’s
is interrupted. This prevents CPU blades from being shut down due to momentary power
interruption. If power to the UPS’s is interrupted, then the system is powered by battery.
The default setting is "60" seconds.
CFG_UPS_COMMUNICATION_LOST_DELAY
Specify the time in seconds the EM card waits until it determines that a UPS is
unavailable after communication with the UPS by SNMP is lost. The default setting is
"180" seconds.
CFG_UPS_ONLINE_DELAY
Specify the time in seconds the EM card waits for connections of online UPS’s at system
boot.
If the the number of online UPS’s does not reach the specified value within this time, the
EM card calculates the maximum power consumption possible for the system assuming
that the remaining UPS’s are not connected.
The default setting is "180" seconds.
Online UPS means one in a normal output state (online or manual bypass state).
CFG_UPS_TIMED_SLEEP_PERIOD
When CPU blades are shut down due to power interruption of UPS’s, all the UPS’s can be
entered into the sleep state temporarily after completion of the shutdown.
Specify the sleep time in minutes. Set the time with multiples of 6 (from 6 to 60 minutes).
When the value is set to "0," only the battery-driven UPS’s are entered into the sleep state.
The default setting is "0."
Generally, the default setting does not need to be changed.
CFG_UPS_GET_COMMUNITY_NAME
Specify the community name for SNMP Get request issued to UPS’s. The default setting
is "public."
CFG_UPS_SET_COMMUNITY_NAME
Specify the community name for SNMP Set request issued to UPS’s. The default setting is
"private."
CFG_UPSn_SERIAL_NUMBER, CFG_UPSn_CAPACITY
The serial numbers and power capacities [W] of up to four UPS’s can be specified. The
default settings are blank characters and "0" [W]. Generally, you do not need to specify
these values.

Notes
UPS management by the EM card requires that the DHCP server of the EM card distribute IP
addresses. Accordingly, enable the DHCP feature of the EM card.
UPS management by the EM card prevents UPS’s from being controlled by
ESMPRO/AutomaticRunningController. When UPS control by
ESMPRO/AutomaticRunningController is required, disable UPS management by the EM card.
When using Windows 2003 Server, "Logon is not required for system shutdown" should be enabled
in the Security Policy tab.
When communication with a UPS is lost, the EM card determines that the UPS is no longer
available. If the number of available UPS’s falls below the minimum required for normal operation,
the EM card shuts down the CPU blades and turns off the UPS’s.
