Precautions when replacing a Host Connector
Observe the following guidelines when replacing a Fan Module.
•
The Host Connector can be replaced with the storage system power
turned on.
•
If SNMP Agent Support is running on a storage system whose Host
Connector will be replaced, an SNMP trap is sent if the Host Connector
is blocked or removed.
•
Hitachi Unified Storage systems support the following Host Connector
interfaces:
-
Fibre Channel 8 G bps
-
iSCSI 10 Gb
The replacement Host Connector must be the same type as the faulty
one you remove. Be sure you do not replace the faulty Host Connector
•
Do not replace the Host Connector during a firmware update. Before
you attempt to replace the Host Connector, confirm in Hitachi Storage
Navigator Modular 2 that the storage system firmware is not being
updated.
Replacing the Host Connector
To replace the Host Connector:
1. Confirm that the red HALM/HSTS LED on the connector is ON. If it is
not ON, visit the HDS Support Portal at portal.hds.com.
2. Remove the cables connected to the controller mounting the Host
Connector to be replaced.
NOTE: If the cable cannot be removed easily, do not pull it by force.
Otherwise, you can damage the cable.
3. Raise the level and remove the Host Connector. The direction in which
the Host Connector is removed depends on the storage system. For the
CBXSS/CBSS/CBXSL/CBSL, use the lever of the Host Connector for #0A,
1A, 0C, 1C located between the Power Unit lever and the storage
system.
4. Wait at least 30 seconds. Otherwise, the new Host Connector may not
recover. The new Host Connector must be the same type as the faulty
one you removed
5. Orient the new Host Connector in the appropriate direction for
installation. Then insert the new Host Connector.
6. Connect the cables.
7. On the CBXSS/CBSS/CBXSL/CBSL, check that the red HALM LED for
ports #A, B, C, D goes OFF.
8. On the CBXSS/CBSS/CBXSL/CBSL or CBL, check that the red HALM LED
or red HSTS LED for ports #E, F, G, H does not go ON.
