Network settings (EM card)
1. Confirm whether the EM card is powered on.
2. Ensure that you have logged in as “Administrator” or a user whose access right is
“ADMINISTRATOR” or “OPERATOR” from a CLI of the EM serial console or the EM console.
(If you have not, log in as “Administrator” or a user whose access right is “ADMINISTRATOR”
or “OPERATOR.”)
3. Determine the network configuration.
IMPORTANT:
 Make sure in advance that IP addresses to be configured are able to use in your network. When
IP address or subnet mask settings become unknown after the configuration, reconfigure them
on the EM serial console.
 Make sure in advance that IP addresses to be configured are able to use in your network.
When IP address or subnet mask settings become unknown after the configuration, reconfigure
them on the EM serial console.
 IP addresses that you are setting should have a subnet address that is able to use in your network.
IP addresses of EM cards, CPU blades and switch modules must have a common subnet mask.
Make up IP addresses with the same subnet in advance.
 Make sure that IP addresses you are setting do not overlap with the IP addresses of other
machines on your network.
 Configure unique IP address for each module to be installed on the blade enclosure.
Even when you operate the blade enclosure with some modules powered off, all the modules
installed on the blade enclosure must have unique IP addresses. (Pay extra attention when you
configure IP addresses of modules without using the DHCP function. If you are using modules
for the first time, all of them may have the same IP address set to them. In such a case, you must
reconfigure IP addresses to give a unique IP address to each one of them.)
 When a first IP address is configured, consecutive numbers are automatically allocated for the IP
addresses of EM cards, CPU blades/switch modules for management LAN. Ensure that none of
the IP addresses has the same address. Not only the first IP address but also
automatically-allocated IP addresses must be within an appropriate range.
 Floating IP is an IP address that dynamically switches according to the status of EM card
(active/standby). Regardless of where the EM card is physically stored, if the EM card is active,
floating IP (active EM) is allocated, and if the EM card is stand-by, floating IP (stand-by EM) is
allocated. When the status of the EM card switches to active/stand-by an occurrence of a failure
on the EM card or the FORCE TAKEOVER command, floating IP is automatically switched
accordingly. By using floating IP, you can use active EM (or stand-by EM) while where the EM
card is physically stored remains transparent. (For detailed information on active EM card etc.,
refer to “EM card” on page 58.)
 Static IP address (EM card slot 1/2) is an IP address that is determined depending on where the
EM card is physically stored. (the left is EM card slot 1, the right is EM card slot 2.)
Static IP address is not affected by whether the status of EM card is active or stand-by.
 The following values can't be specified for EM cards, CPU blades and switch modules.
*.*.*.0, *.*.*.255 ("*": the wildcard character)
