The SIM boards, which are similar to I/O Modules, are hot-swappable so you can replace them
without removing power to the system. The SIM boards are multi-pathed, so you can remove
one of the SIM boards at any time, regardless of the state of the blue SIM OK indicator.
1. A faulted SIM board is indicated by an amber LED. Go to the Maintenance >
Hardware section of the BUI, click the right-arrow icon
appropriate disk shelf row, and then click Slot to view details, or click the locator
icon to turn on the locator LED.
2. Locate the failed SIM at the back of the disk tray.
3. Label and disconnect the tray interface cables.
4. Use two hands to disconnect the SAS cable. Grasp the metal body of the
connector with one hand and firmly grasp and pull the tab gently toward the
connector body with the other, then pull the connector body outward to extract it
from the bulkhead. Do not twist or pull the tab in any direction other than parallel
with the connector body or it may break. If the tab breaks, use a small sharp
object (such as a fine-tipped screwdriver) to lift the metal spring at the top of the
connector shell to unlatch it.
5. Loosen the two extraction arm captive screws using your thumb and forefinger.
If the captive screws are too tight to loosen by hand, use a No.2 Phillips
screwdriver to loosen each screw.
