Notices

Note on using the RPC port
For security reasons, the factory settings do not allow other machines to access
NEC Express5800/320Lb(-R) via the RPC port. With the factory settings, you
cannot use applications, such as NFS, that use the PRC port.
1) Configuration at the time of shipment and reinstallation
# /sbin/iptables -A INPUT -p tcp --dport 111 -i ! lo -j DROP
# /sbin/iptables -A INPUT -p udp --dport 111 -i ! lo -j DROP
2) Configuration File
The configuration is stored in the following file.
/etc/sysconfig/iptables
To use applications such as NFS, you need to permit the access via the RPC
port. See the following example and change the settings in
/etc/sysconfig/iptables to permit the access
[Example for changing the configuration]
To permit the access from a particular IP address only (e.g. 192.168.0.10):
# /sbin/iptables -I INPUT -p tcp --dport 111 -s 192.168.0.10 -j ACCEPT
# /sbin/iptables -I INPUT -p udp --dport 111 -s 192.168.0.10 -j ACCEPT
# /sbin/iptables-save > /etc/sysconfig/iptables

Note for reinstallation
Follow the steps described in the User’s Guide to perform reinstallation with the
backup CD-ROM (shipped with the NEC Express5800/ft series) and configure
settings after reinstallation. When you perform reinstallation, make sure to follow
the procedures for preparation described in “Linux Setup” of User’s Guide (Setup)
.
(Remove optional PCI boards and other peripheral devices. Insert one HDD to the
slot 1 of each PCI module. Use the CD-ROM drive in the group 1 of the PCI
module for reinstallation. If the power switch lamp of the group 2 is on, follow the
steps described in “Linux Setup” of User’s Guide (Setup) to turn on a power switch
lamp of the group 1.

Note on removing and inserting an internal hard disk
Contact your sales representative to replace an internal hard disk.
4
Note on replacing a CPU module and/or PCI module
Contact your sales representative to replace a CPU module and/or PCI module.
5
Note on returning a status with redundant CPU modules
When you restore the redundant status after stopping either of CPU modules due to
a system failure or replacement, the system may look stopped approximately for 5
seconds after the completion of the redundancy processing. This does not affect
operation of the system. If monitoring from a client machine by a timer is
performed for the process of accessing NEC Express5800/320Lb(-R) server, you
should make monitoring settings taking this duration of time into account.
