Adding Blades to the I/O Management Unit
The instructions in the following subsections are to be used for upgrading existing library configurations. If
you are installing blades in a new library, see Installing Drives and Blades
on page 97 for instructions.
If you are adding blades to the I/O management unit, you must first install a cooling assembly if there is not
one in the module.
Installing the I/O Management Unit Cooling Assembly
The I/O management unit cooling assembly contains the fans that regulate temperature for the I/O
management unit.
Required tools: #1 Phillips screwdriver, ESD strap
1 Open the service door of the module.
2 Attach the ESD strap to your wrist and to an unpainted surface inside the door.
3 Use a #1 Phillips screwdriver to remove the cover over the slot where the I/O management unit cooling
assembly will be installed.
4 Remove the I/O management unit cooling assembly from the packaging.
You do not need to take the library offline in order to install the I/O management
cooling assembly, CMBs, or FC I/O blades. However, if the library is not taken
offline RAS tickets will be posted.
