Installing A Switching Fabric Module - HP FlexFabric 12900 series Installation Manual

Installing a switching fabric module

Every 12910 AC switch has six switching fabric module slots numbered 10 through 15. For the proper
operation of the switch, at least one switching fabric module must be installed in slot 10, slot 1 1, or slot
12.
The gray edged switching fabric module slots of a 12910 AC switch are located at the rear panel. The
switching fabric modules are horizontally oriented. When installing a switching fabric module, make sure
its PCB faces up.
To install a switching fabric module:
1. Wear an ESD-preventive wrist strap, and make sure it makes good skin contact and is well
grounded. For more information, see
2. Remove the filler panel (if any) from the target slot. Keep the filler panel for future use. See

3. Loosen the captive screws on the protection box, hold the ejector levers on the switching fabric
module, pressing the buttons on the levers, pull the ejector levers outward, and pull out the module
from the protection box. See
Keep the protection box for future use.
