Getting Started

This chapter provides information and procedures needed to install and make the Sun Netra CP3240 switch operational. This chapter should be read before using the board.

In addition to this chapter, refer to the following safety documentation:



caution icon Caution - When the system is plugged in, energy hazards are present on the midplane. Do not reach into the enclosure.




caution icon Caution - Static electricity can damage electronic components. Wear a wrist strap grounded through one of the system’s ESD ground jacks when removing and replacing hot-swappable components.


This chapter contains the following topics:


1.1 System Requirements

The following sections briefly describe the minimum system requirements and the configurable features. Links are provided to other chapters and appendices containing more detailed information.

1.1.1 Connectivity

The switch can work in any AdvancedTCA shelf. It is mainly designed to be used as hub blade, however, it can also operate a node or a full-mesh blade.

1.1.1.1 Hub Connectivity

In AdvancedTCA. the hub board defines the system, so it is important that it be put in the correct slot. In all shelves there are two slots specifically designated for hub boards, logical slots 1 and 2. If the slots are not labeled, these slots are easily identifiable because they have a larger number of Zone 2 connectors than the other slots (the only slots with all five Zone 2 connectors).

Base is always routed in a dual star. This means every node slot has a Base channel routed to each of the hub slots. Independent of how the Fabric is used, a hub board is always needed for Base. If full mesh node boards are used in a full mesh shelf, a hub board is not needed for Fabric.

1.1.2 Electrical and Environmental

The switch has the following power requirements:


TABLE 1-1 Power Requirements

The 48VDC has a tolerance of 0VDC to 75VDC without damage. The switch will operate when 48VDC is 36VDC to 72VDC, inclusive.



caution icon Caution - Any input voltage outside the range of 0VDC to 75VDC can damage the switch.


The switch requires air flow. A minimum of 100 LFM should be kept on the board at all times. If an RTM is being used, active RTM cooling is not required.



caution icon Caution - None of the integrated chips junction temperature should exceed 125˚C. The switch requires air flow to meet this requirement. Testing should be done in your shelf to find the quantity of air flow needed. 100 LFM is the recommended minimum quantity of air flow.


The switch might contain materials that require regulation upon disposal. Please dispose of this product in accordance with local rules and regulations. For disposal or recycling information, please contact your local authorities or the Electronic Industries Alliance at http://www.eiae.org/.


1.2 Unpacking

Check the shipping carton for damage. If the shipping carton or contents are damaged, notify the carrier and Sun. Retain the shipping carton and packing material for inspection by the carrier. Obtain authorization before returning any product to Sun. Refer to the Netra CP3240 Switch Getting Started Guide (820-3254) for return instructions.



caution icon Caution - This board must be protected from static discharge and physical shock. Never remove any of the socketed parts except at a static-free workstation. Use the anti-static bag shipped with the product to handle the board. Wear a wrist strap grounded through one of the system's ESD ground jacks when installing or servicing system components.



1.3 Handling Switches



caution icon Caution - The system is sensitive to static electricity. To prevent damage to the assembly, always connect an antistatic wrist strap between you and the system.




caution icon Caution - Do not flex the switches; the surface-mounted components can break if the switch is bent.


To minimize the amount of switch flexing, observe the following precautions:



caution icon Caution - The heat sinks on a switch can be damaged by incorrect handling. Do not touch the heat sinks while installing or removing a switch. Hold a switch only by the edges. If a heat sink is loose or broken, obtain a replacement switch.




caution icon Caution - The heat sinks on a switch can be damaged by improper packaging. When storing or shipping a switch, ensure that the heat sinks have sufficient protection.



1.4 Connectors

The switch includes several connectors to interface to application-specific devices. Refer to the Chapter B for complete connector descriptions and pin outs.


1.5 Jumper Options

The switch provides several jumper configuration options for features. Location figures and descriptions are provided in Chapter 3.

1.8 Removing and Installing Switches

This section describes how to remove and install switches.

If you are hot-swapping the rear transition module for a switch, you must remove the switch from the front of the system before removing the rear transition module from the rear of the system. Do not remove the rear transition module without first removing the accompanying switch from the front.

1.8.1 Removing a Switch Set

Following are the instructions for removing a switch and, if necessary, the accompanying rear transition module.

1.8.1.1 Removing a Switch From the Front of the Server

1. Move the front cable management bracket to the lower position (FIGURE 1-6).

FIGURE 1-6 Front Cable Management Bracket in Lower Position


This figure shows how to move the front cable management bracket to the lower position.

2. Disengage the injector/ejector mechanisms at the top and bottom of the board to notify software that the board is about to be removed. Wait for the Hot-Swap LED to light.

FIGURE 1-7 shows the proper way to remove or insert a hot-swappable board into a system.

FIGURE 1-7 Injector/Ejector on the Switch (Open Position)


3. Disconnect all cables connected to the switch.

4. Loosen the two board retention screws that fasten the board to the enclosure.

5. Open the ejectors fully, rotating the handles outward until the board disengages from the midplane.

6. Slide the board evenly out of the enclosure.

7. Determine if you are going to replace the rear transition module.



Note - As long as the switch is removed from the slot, and the system is running with only the single remaining switch, you do not have redundancy for that component. Both switches must be installed and running to have redundancy for that component.


1.8.1.2 Removing a Rear Transition Module for a Switch

1. Remove the switch from the front of the server, if you have not already done so.

Refer to Removing a Switch From the Front of the Server for those instructions. Do not remove the rear transition module until you have first removed the switch.



Note - Opening the handle on the RTM shuts down both the RTM and the switch.


2. Disconnect any cables connected to the rear transition module for the switch.

3. Loosen any retention screws that fasten the module to the enclosure.

4. Open the ejectors fully, rotating the handles outward until the board disengages from the midplane.

5. Slide the module evenly out of the enclosure.

6. Install a replacement rear transition module or a filler panel to maintain the enclosure’s shielding and cooling performance.

Refer to Section 1.8.2.1, Installing the Rear Transition Module for a Switch.



caution icon Caution - Failure to cover all rear panel slots with rear transition modules or filler panels can negatively impact the cooling of the system.


1.8.2 Installing a Switch Set

If you have a rear-access server, you must install the rear transition module before installing the front switch.

1.8.2.1 Installing the Rear Transition Module for a Switch

1. Choose an appropriate slot for the rear transition module.

Rear transition modules must be installed inline behind the accompanying front board. For example, if the accompanying front board is installed in slot 7, its rear transition module must be installed at the back of the system in slot 7.

2. Remove the filler panel, if necessary.

3. Prepare the rear transition module by opening its injector/ejector handles.

4. Carefully align the edges of the board with the guides in the slot.

Look into the enclosure to verify correct alignment of the rails in the guides.



caution icon Caution - Do not force the module into the slot. If it does not fit properly, check to ensure that you have the correct matching RTM for the switch.


5. Keeping the board aligned in the guides, slide the board in until the injector/ejector mechanisms engage the retention bar.

6. Simultaneously push in the board and rotate the injector/ejector handles to their closed positions (rotate inward) to seat the midplane connectors.

7. Tighten the board retention screws to anchor the board in the shelf.

8. Connect the cables to the rear transition module.

1.8.2.2 Installing a Switch

1. Locate the switch slots.

The switches can be inserted only in slot 7 or slot 8 in the Netra CT 900 server.

2. Move the front cable management bracket to the lower position (FIGURE 1-6).

3. Remove the filler panel, if necessary.

4. Prepare the switch by opening its injector/ejector handles (FIGURE 1-7).

5. Carefully align the edges of the board with the guides in the slot.

Look into the enclosure to verify correct alignment of the rails in the guides.

6. Keeping the board aligned in the guides, slide the board in until the injector/ejector mechanisms engage the retention bar.

7. Simultaneously push in the board and rotate the injector/ejector handles to their closed positions (rotate inward) to seat the midplane connectors.

If system power is on, the Hot-Swap LED should light up. The Hot-Swap LED should blink for several seconds, and then go off. If the Hot-Swap LED does not go off after several seconds, push harder on the injector/ejector handles to verify that they are pushed in all the way.

8. Tighten the board retention screws to anchor the board in the shelf.

9. Connect the cables to the switch.
