HP EML E-series Tape Libraries - Manual (Page 86)

• The power LED is on and the ACT/LNK LEDs are off instead of green (see
“ HP StorageWorks e2400-FC 2Gb interface controller ” on page 57).
• The power LED is off.
• You might need to find out which tape drives are connected to each interface controller to identify
which interface controller to replace.
2. Use your backup software to stop all library activity and make sure the picker is empty.
3. Turn off the power to the library.
4. Label the cables or write a note that shows the locations of all the cables plugged into the interface
controller to make it easier to reconnect them later.
5. Unplug all cables from the interface controller.
6. Loosen the captive screws in the black ejector handles at both ends of the interface controller.
Use a #1 Phillips screwdriver.
7. Push the ejector handles to the outside.
8. Pull the ejector handles to remove the interface controller from the library.

Replacing an e2400-FC 2Gb interface controller
NOTE:
You can install the interface controller in two locations in the library:
• The middle slot in the card cage in the base module. You must always have an interface controller
installed there.
• Any of the slots in the card cage expansion module. You must have one interface controller installed
there for every four additional LTO2 or LTO3 tape drives that you install.
1. Orient the interface controller as shown in Figure 49 on page 86. Align the interface controller with
the guides in the slot in the card cage and slide the interface controller into the library.
2. Push the ejector handles to the inside to fully engage the interface controller into the backplane.
3. Tighten the captive screws in both ejector handles.
4. Plug the cables into the interface controller exactly as they were plugged into the original interface
controller (see the labels on the cables or the note that you wrote).
