SGI C1103-G15 (01) PDF Document

Before operating or servicing any part of your SGI C1103-G15 system, you must familiarize yourself with the following safety precautions to prevent personal injury or damage to the equipment:

ESD Precautions:

Observe all ESD (Electrostatic Discharge) precautions, as failure to do so can result in damage to the equipment. Wear an SGI approved wrist strap when handling any ESD-sensitive device to eliminate possible ESD damage. Connect the wrist strap cord directly to earth ground.

High-Voltage Warning:

Keep fingers and conductive tools away from high-voltage areas. These areas are indicated with high-voltage warning labels. Failure to follow this precaution can result in serious injury or death.

System Shutdown:

Power off the SGI C1103-G15 system only after the system software has been shut down in an orderly manner. If you power off the system before halting the operating system, data may be corrupted.

Lithium Battery Replacement:

If a lithium battery is installed as a soldered part, only qualified SGI service personnel should replace it. For other types of batteries, replace it only with the same or an equivalent type recommended by the battery manufacturer to avoid a potential explosion. Discard used batteries according to the manufacturer’s instructions.

First, inspect the shipping box for any damage. If the server itself shows damage, you should file a damage claim with the carrier who delivered it.

When choosing a location for the rack unit that will hold the SGI C1103-G15 system, ensure it meets the following criteria:

• It should be a clean, dust-free area.

• The area must be well ventilated.

• Avoid areas where heat, electrical noise, and electromagnetic fields are generated.

• The system must be placed near a grounded power outlet.

For proper access and airflow, follow these clearance guidelines:

• Leave approximately 25 inches (63.5 cm) of clearance in front of the rack to open the front door completely.

• Leave approximately 30 inches (76.2 cm) of clearance in the back of the rack for sufficient airflow and ease of servicing.

When installing and operating the SGI C1103-G15 in a rack, adhere to the following precautions for safety and stability:

Rack Stability:

• Ensure the leveling jacks on the bottom of the rack are fully extended to the floor with the full weight of the rack resting on them.

• For a single rack installation, stabilizers should be attached to the rack.

• For multiple rack installations, the racks should be coupled together.

• Always make sure the rack is stable before extending a component from it.

• Extend only one component at a time. Extending two or more simultaneously may cause the rack to become unstable.

Server Placement and Cooling:

• Install the heaviest server components on the bottom of the rack first, and then work your way up.

• Always keep the rack’s front door and all panels and components on the servers closed when not servicing to maintain proper cooling.

• Make sure all power and data cables are properly connected and not blocking the chassis airflow.

General Server Precautions:

• Review all electrical and general safety precautions before you begin.

• Allow hot-plug disk drives and power supply modules to cool before touching them.

To install the SGI C1103-G15 into a rack, follow these steps:

Step 1: Install the Inner Rails

The left and right side inner rails are pre-attached to the SGI C1103-G15 chassis. You can proceed to the next step.

Step 2: Install the Outer Rails into the Rack

• Measure the distance from the front rail to the rear rail of the rack.

• Attach a short bracket to the front side of the right outer rail and a long bracket to the rear side of the same rail.

• Adjust the brackets so the rail fits snugly into the rack.

• Secure the short bracket with two M4 screws and the long bracket with three M4 screws.

• Repeat this process for the left outer rail.

Step 3: Install the Server into the Rack

• Line up the rear of the chassis rails (attached to the server) with the front of the rack rails (installed in the rack).

• Slide the chassis rails into the rack rails, keeping the pressure even on both sides. You may need to depress the locking tabs when inserting the unit.

• When the server is pushed completely into the rack, you should hear the locking tabs “click” into place.

To access the inside of your SGI C1103-G15 while it is mounted in a rack, follow these steps:

1. Grasp the two handles on either side of the server and pull the system straight out until it locks. You should hear a “click”.

2. Remove the four screws that secure the top cover: two on the sides and two on the top.

3. Place your thumbs in the two rectangular recesses on the cover and push the cover away from you (toward the rear of the chassis) until it stops.

4. You can now lift the top cover from the chassis to gain full access to the internal components.

To remove the system completely from the rack, depress the locking tabs in the chassis rails (push the right-side tab down and the left-side tab up) and continue to pull the system out past the locked position.

The front control panel of the SGI C1103-G15 provides system status through buttons and LEDs.

Control Panel Buttons:

• Reset: Pressing this button will reboot the system.

• Power: This is the main power button used to apply or turn off the main system power. Depressing this button removes the main power but keeps standby power supplied to the serverboard.

Control Panel LEDs:

• Universal Information LED (Overheat/Fan fail/UID): This LED is bi-color (Red/Blue). Its status indicates the following:

• NIC 1 and NIC 2 activity LEDs: These LEDs flash to indicate network activity on LAN1 and LAN2, respectively.

• HDD activity LED: This light flashes to indicate disk drive activity on the server.

• Power LED: This LED indicates that power is being supplied to the system’s power supply unit. It should normally be illuminated when the system is operating.

Before handling memory modules, ensure you are taking proper ESD precautions, such as using a grounded wrist strap. The serverboard has sixteen 240-pin DIMM slots.

To install a DIMM:

1. Insert the memory DIMM vertically into an empty slot. Pay attention to the alignment notch along the bottom of the DIMM to prevent inserting it incorrectly.

2. Gently press down on the DIMM until it snaps into place and the release tabs on both ends of the slot lock the module.

3. Repeat for all DIMMs you wish to install.

To remove a DIMM:

1. Use your thumbs to gently push the release tabs near both ends of the memory module outwards.

2. This will release the DIMM from the slot, allowing you to lift it out.

Due to memory allocation to system devices, the amount of memory that remains available for operational use is reduced. The following table shows a possible system memory allocation and availability with a total of 4 GB of RAM installed:

The SGI C1103-G15 includes pre-installed riser cards for adding PCIe cards. The PCIe card cannot be “hot installed,” so the system must be powered down. Follow these steps to add a PCIe add-on card:

1. Power down the system and disconnect the power cord.

2. Pull the unit straight out of the rack until it locks.

3. Remove the top cover of the chassis to gain full access to the inside of the server.

4. Remove the screws for the PCIe carrier.

5. Remove the carrier from the chassis.

6. Install your PCIe add-on card into the carrier.

7. Reinstall the PCIe carrier into the chassis and secure it with its screws.

8. Replace the top cover, push the server back into the rack, and reconnect power.

If a fan fails on your SGI C1103-G15, the red overheat/fan fail LED on the control panel will blink on and off.

The system can continue to run with a failed fan, but you should replace it at your earliest convenience with the same type and model. To identify the failed fan, you can remove the top chassis cover while the system is still running. Once identified, power down the system before replacing the fan. Removing the power cord is also recommended as a safety precaution.

The SGI C1103-G15 features hot-swap drive bays, allowing you to replace drives without powering down the system. Note that your operating system must have RAID support to enable this capability.

To mount a drive in a carrier:

1. Obtain a new or replacement hard disk drive.

2. Install the drive into the carrier with the printed circuit board side facing down, ensuring the mounting holes align.

3. Secure the drive to the carrier with the side screws.

To install or remove a drive carrier:

1. To remove a carrier, push the release button located beside the drive LEDs.

2. Swing the handle fully out and use it to pull the carrier straight out of the chassis.

3. To install a carrier, simply slide it into an empty bay and push it in until it is fully seated. Close the handle to lock it in place.

Note: When installing the hard drive carrier that is next to the power supply, the power supply handle must be lifted before extending the hard drive carrier handle or before inserting the carrier into the drive bay. Regardless of how many drives are installed, all three drive carriers must remain in the chassis to maintain proper airflow.

If the power supply unit fails, the system will shut down. The LED on the front of the power supply should be off (unlit) in case of failure.

To Remove a Failed Power Supply:

1. Power off the system and unplug the AC power cord from the system. The power supply may be hot; allow at least 5 minutes for it to cool down.

2. Push the release tab on the front of the power supply.

3. Pull up the power supply handle.

4. Extract the supply from the chassis by pulling it outward.

To Install a New Power Supply:

1. Obtain an exact replacement model power supply.

2. Insert the new unit into the chassis and push it in until it is fully seated. You should hear an audible “click”.

3. Reconnect the AC power cord and then press the power button on the front of the chassis to resupply power to the system.
