Task List; Unpacking An Enc Unit - Hitachi AMS 2000 Series Service Manual

NOTE: If the Power Saving storage feature is installed, wait at least 20
seconds after removing a part before reinstalling it or installing a
replacement part. Do not replace any parts while the disks are spinning up.
To determine if the drives have started to spin up, look for the message
"The request of spin up of disk drives is accepted" in the Navigator 2 Alerts
window. If you see that message, do not reinstall the part until the
message "I1GZ00 The spin up of disk drives completed" is displayed. This
indicates that the drives are at operating speed.

Task list

Complete the following tasks to replace an ENC unit. For detailed
information, see the sections with the same titles that are in the table.
1. Troubleshoot the array according to the instructions in the Hitachi AMS
2100/2300 Storage System Service Guide and the error message(s) and
instructions in the Navigator 2 Alerts window.
2. Unpack the ENC unit and verify that you have the correct part.
CAUTION! Do not disconnect the ENC cables first. Partially remove
the ENC unit from the expansion unit or modular 2U SAS expansion
unit and then disconnect the ENC cables.
3. Slide the ENC unit partway out of the expansion unit.
4. Disconnect the ENC cables from the unit. If the connectors on the cables
are tight in the socket, gently wiggle them out of the sockets. Be careful
not to bend the cable sharply while unplugging the cable.
5. Remove the failed ENC unit from the expansion unit.
6. Slide the new ENC unit partway into the slot.
7. Connect the ENC cables to the ENC unit.
8. Slide the ENC unit all the way into the expansion unit.
9. Open the lock lever just far enough so that the tab on the lock lever can
be inserted into the slot in the frame of the expansion unit or modular
2U SAS expansion unit when you slide the ENC unit into the unit.
10. When the tab on the lock lever is engaged in the slot, push the lock lever
closed until you hear the lock button click. This pulls the ENC unit all the
way into the expansion unit or modular 2U SAS expansion unit and plugs
it in.
11. The firmware from the other ENC unit in the expansion unit will
automatically be loaded onto the ENC unit you just installed.

Unpacking an ENC unit
