Notes on use
CAUTION

Do not look directly into the laser beam. Do not look into the laser beam using an optical
instrument. 10GBASE-R transceiver uses laser beam that can damage your eyes, which
is colorless, transparent, and invisible.

Do not remove the cover of an unused board. Under the laser module cover, the laser
beam is being emitted.

In the default settings, the port of line 1 is configured for a dedicated virtual local area
network (VLAN) for management and cannot communicate with a server blade and other
external ports. Therefore, you need to change the switch settings suitable for your system
configuration. After the changes, be sure to save the configuration information using the
save command, otherwise, the data is lost when the system is powered off.

In the default settings, the ports of line 5 to 12 and line 15 to 22 connected to the server
blade are configured as edge ports (portfast). This setting aims to prevent the network from
being affected by operations such as rebooting of the server blade. When you change the
setting, it is recommended to set the port as edge port.

The switch module is provided with Spanning tree as standard configuration. The external
ports of line 2 to 4 cannot be communicated for 30 seconds after the cable is connected.

A different type of LAN controller is installed in each server blade model. Connection ports
for server blades, line 5 to 12 (slot 0 to 5) and line 15 to 22 (slot 2 to 5), are set by default as
shown in the table below. Use a port setting value specific to each server blade to avoid
communication errors.
Server blade model Setting for server blade connection port
X55A1/X55A2/X57A1/X57A2: speed 1000
Models launched in or before March 2012 duplex full
X55R3/X55S3: speed auto*
Models launched in or after April 2012 duplex auto*
* You need not specify the value in a configuration file because it is set before configuration.

To restore the factory-set configuration, use one of the following methods:
Enter the device manager mode and execute the erase configuration command.
The CD attached to this device contains the
default file
.
Apply the default file as described in "Restoring configuration (applying to startup-config)".
In this case, use the “default” file according to “readme.txt” in the CD attached to this device.

Since line 1 to line 4 of 10 Gbps LAN switch module and line 1 to line 4 of 1 Gbps LAN
switch module are based upon Auto-MDI/MDI-X, both cross and straight cables are usable.
This function is operational when auto negotiation is effective. Medium dependent interface
crossover (MDI-X) is usable when fixed half duplex or fixed full duplex is specified.

When connecting to the LAN switch module over the segment, make sure to set the default
gateway. Set the static routing to set the default gateway of the LAN switch module. The
example of the setting is shown below.
ip route
0.0.0.0 0.0.0.0 192.168.1.1
*: ”192.168.1.1”
is the address of the default gateway.
For the detail about the ip route command, see “Configuration Command Reference Vol.2”
in the CD-ROM attached to this device.

The default configuration during shipment includes the management port settings to
connect the LAN switch module to the management module.
