Setting the IP Address

Use the following steps to set the IP Address:

1.Use the arrow keys to highlight the IP Address field.

2.Enter the IP address into this field. The format for this entry is XXX.XXX.XXX.XXX, with values for XXX being from 0 to 255. The screen beeps if non-numerics or adjacent dots are entered. If the entry does not have three dots, it is rejected.

3.Press ENTER. The IP address appears and the natural subnet mask for the user is generated and also appears.

4.Use the arrow keys to highlight the SAVE option, then press ENTER or F6. The “SAVED OK” message appears indicating that the changes have been saved to memory.

NOTE

The first time an attempt is made to exit the screen without saving the changes, a “NOT SAVED?” message is displayed. The edits are lost if the user proceeds to exit without saving the changes.

Setting the Subnet Mask

NOTE

Consult the Network Administrator prior to setting the Subnet Mask.

The subnet mask defines how the SEHI treats SNMP Trap IP destination addresses in its Trap Table.

•Set the subnet mask when workstations in the Trap Table reside on a different subnet (i.e., across a gateway or router), and these workstations are to receive SNMP traps.

•Use the subnet mask factory default setting of 0.0.0.0 when all trap designated workstations are on the SEHI subnet.

Use the following steps to set the subnet mask:

1. Use the arrow keys to highlight the SubNET Mask field.
