5.3 Configuring the Network Environment

This software uses SNMP communication to find devices. Therefore, a storage device whose SNMP agent is inactive cannot be detected. The storage device's SNMP agent must be started.

Check the network environment, access authorization and communication mode settings between the Express Manager server and the Disk storage system. Make sure that one communication mode is not set to "Auto Negotiation" while the other is set to "Full (full duplex)"

Refer to the manual of the Disk storage system and check the network environment settings.

If the network environment configurations are insufficient, set them with ETERNUS Web GUI or FibreCAT SX WBI (web-browser interface).

When a firewall is placed, set the following port numbers to be able to pass the firewall.

Table 5.2 Settings for a firewall between the Express Manager server and the ETERNUS Disk storage system
Port Number	Protocol	Communication Start Direction
23	tcp	From Express Manager server to ETERNUS Disk storage system.
161	udp	From Express Manager server to ETERNUS Disk storage system.
162	udp	From ETERNUS Disk storage system to Express Manager server.
1999	tcp	From Express Manager server to ETERNUS Disk storage system.

Note

The telnet protocol port and the ETERNUS maintenance protocol port should be open in the firewall setting on the ETERNUS Disk storage system.

Table 5.3 Settings for a firewall between the Express Manager server and the FibreCAT SX Disk storage system
Port Number	Protocol	Communication Start Direction
161	udp	From Express Manager server to FibreCAT SX Disk storage systems.
162	udp	From FibreCAT SX Disk storage systems to Express Manager server.

Table 5.4 Settings for a firewall between the Express Manager server and the Express Client PC or server
Default Port Number	Protocol	Communication Start Direction
9853	tcp	From Express Client PC or server to Express Manager server.
9854	tcp	From Express Client PC or server to Express Manager server.

Note

When firewall of OS is made effective.

The Express doesn't use Microsoft SNMP Trap Service to receive the SNMP Trap.

Therefore, SNMP Trap cannot be received by making "SNMP Trap Service (UDP in)" effective in "Inbound Rules" of "Windows Firewall with Advanced Security".

Please add Inbound Rule of the following content by using "New Inbound Rule Wizard".

Item	Set value
Rule type	port
Protocol	UDP
Port	Local 162
Action	Allow the connection
