3. Perform the following, according to switch type:
• For Core Switch 2/64, SAN Director 2/128, and 4/256 SAN Director, click the slot subtab that
corresponds to the correct slot for the logical switch.
• For 4/8 SAN Switch, 4/16 SAN Switch, SAN Switch 2/8V, SAN Switch 2/16V, SAN Switch
2/32, 4Gb SAN Switch for HP p-Class BladeSystem, and SAN Switch 4/32, proceed directly to
the next step.
4. Select a port by clicking anywhere in the row for that port.
5. Select a distance from the Long Distance drop-down list that corresponds to the port.
Depending on the distance selected, this might require an optional license. For information about the
various distances, see
If you select a long-distance setting of LD, you must also enter a value in the Desired Distance column
for that port number:
a. Double-click the Desired Distance box for the port, as shown in
b. Enter a number in the field to indicate the distance in kilometers:
• For 1 Gbit/sec ports, enter a number between 10 and 500, inclusive.
• For 2 Gbit/sec ports, enter a number between 10 and 250, inclusive.
• For 4 Gbit/sec ports, enter a number between 10 and 125, inclusive.
This value is the upper limit for calculating buffer availability for other ports in the same port group.
If the actual distance is more than the desired distance, the port operates in buffer-limited mode.
c. Press Enter or click another port entry for the value to be accepted.
6. Optional: If the fabric contains HP StorageWorks 1 GB switches extended ISLs, select the On radio
button for Long Distance Compatibility. The switch must be disabled before you can select this option.
If you select this option, you must have an Extended Fabrics license, and both E_Ports in an ISL must be
configured with the same long-distance compatibility setting. The SAN Switch 4/32 cannot be part of
such a fabric.
7. Click Apply.
