Removing and Replacing a J4400 Array SIM Board
|
This document describes replacement procedures for the SAS Interface Module (SIM) customer replaceable unit (CRU) installed in the Sun Storage J4400 Array. This document assumes you have:
- Identified the disk tray containing the failed SIM board.
- Received the replacement SIM board.
This product is intended for restricted access whereby access is controlled through the use of a means of security (for example, key, lock, tool, badge access) and personnel authorized for access have been instructed on the reasons for the restrictions and any precautions that need to be taken.
ESD Precautions
When performing this service action, observe the following electrostatic discharge (ESD) precautions:
- Remove all plastic, vinyl, and foam material from the work area.
- Wear an antistatic wrist strap at all times when handling any CRU.
- Before handling any CRU, discharge any static electricity by touching a grounded surface.
- Do not remove a CRU from its antistatic protective bag until you are ready to install it.
- After removing a CRU from the cabinet, immediately place it in an antistatic bag or antistatic packaging.
- Handle any card that is part of a CRU only by its edges and avoid touching the components or circuitry.
- Do not slide a CRU over any surface.
- Limit body movement (which builds up static electricity) during the removal and replacement of a CRU.

Removing and Replacing a SIM Board
This section describes how to remove and replace a SIM board.
|
|
Caution - Potential loss of data access - Never remove a SIM board unless the SIM Locate LED is blue (see FIGURE 1).
|
Caution - Electrical Power Hazard -The power supplies in this equipment can produce high energy hazards. Only personnel with authorized access to this equipment should remove and replace modules in the system.
 To Remove a SIM Board
|
1. From the back of the disk tray, locate the failed SIM. The SIM Locate LED is blue (see FIGURE 1).
2. Label and then disconnect the tray interface cables.
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.
|
|
Caution - Do not twist or pull the tab in any direction other than parallel with the connector body or you might break the tab. 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.
|
3. 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 #2 Phillips screwdriver to loosen each screw.
4. Pull each ejector tab outward and push to the sides to release and partially eject the SIM from the chassis (see FIGURE 2).

5. Grasp the middle of the SIM board and slide it out of the slot.
|
|
Caution - Use care when handling either the new or failed SIM board. Make sure all ESD precautions are being followed.
|
Note - The SIM boards are hot-swappable and you do not need to disconnect power from the system or other components in order to replace one of these components.
|
|
Caution - For products with multiple power cords, all power cords must be disconnected to completely remove power from the system.
|
To Replace a SIM Board
|
1. Unpack the new SIM board and do one of the following:
- Place the failed SIM board in the packing materials so that you can return it to Sun for proper disposal.
- Properly dispose of the failed SIM board.
2. Pull the ejector arms to the full open position.
3. Align the new SIM board with the open slot and slide it into the tray until the ejector arms contact the tray connectors and begin to swing closed (see FIGURE 3).

4. Simultaneously swing both ejector arms in until they are flush with the SIM board panel to seat the board.
5. Tighten both captive screws to secure the board.Figure showing back view of J4200 and SIM insertion action.
6. Reconnect the tray interface cables to their original locations.
To Verify and Complete the SIM Board Replacement
|
1. Wait approximately 60 seconds for the SIM board to complete its boot process, at which point ensure that the following is true:
- The Power LED is solid green.
- The SIM Locate LED is off (see FIGURE 1).
