SUPERMICRO MBE-628L-416 (01) PDF Document

The SUPERMICRO MBE-628L-416 is a 6U enclosure that can house up to 28 MicroBlade servers. It supports server blades based on Intel Atom processors. The capabilities are as follows:

Notes for the MBE-628L series:

• Supports server blades based on Intel Atom processors.

• The blade BMCs are deactivated as they are redundant with the CMM.

• Supports 1G or 2.5G.

• The MBI-6418A blade provides up to 112 nodes per enclosure. Each node will have two NICs—it will require a total of 224 ports. The second NIC for each node will be deactivated and the speed will be 2.5G.

The front of the SUPERMICRO MBE-628L-416 enclosure features status indicators, a LAN port, and a console port.

If the master CMM fails, the front LAN port and Console port are connected to the slave CMM.

First, inspect the box in which the enclosure was shipped and note if it was damaged. If so, file a claim with the carrier. The box should include the rackmount hardware needed to install it into the rack.

When choosing a setup location:

• The system should be situated in a clean, dust-free area that is well ventilated. Avoid areas where heat, electrical noise and electromagnetic fields are generated.

• Leave enough clearance in front of the rack so that you can open the front door completely (~25 inches) and approximately 30 inches of clearance in the back of the rack to allow sufficient space for airflow and access when servicing.

• This product should be installed only in a Restricted Access Location (dedicated equipment rooms, service closets, etc.).

• This product is not suitable for use with visual display workplace devices according to §2 of the German Ordinance for Work with Visual Display Units.

Please follow these rack precautions and mounting considerations for your safety and the proper operation of the SUPERMICRO MBE-628L-416.

Rack Precautions:

• Ensure that the leveling jacks on the bottom of the rack are extended to the floor so that the full weight of the rack rests on them.

• In single rack installations, stabilizers should be attached to the rack. In multiple rack installations, the racks should be coupled together.

• Always make sure the rack is stable before extending a server or other component from the rack.

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

• Determine the placement of each component in the rack before you install the rails.

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

• Use a regulating uninterruptible power supply (UPS) to protect the server from power surges and voltage spikes and to keep your system operating in case of a power failure.

• Allow power supply modules to cool before touching them.

• When not servicing, always keep the front door of the rack and all covers/panels on the servers closed to maintain proper cooling.

Rack Mounting Considerations:

• Ambient Operating Temperature: If installed in a closed or multi-unit rack assembly, the ambient operating temperature of the rack environment may be greater than the room’s ambient temperature. Therefore, consideration should be given to installing the equipment in an environment compatible with the manufacturer’s maximum rated ambient temperature (TMRA).

• Airflow: Equipment should be mounted into a rack so that the amount of airflow required for safe operation is not compromised.

• Mechanical Loading: Equipment should be mounted into a rack so that a hazardous condition does not arise due to uneven mechanical loading.

• Circuit Overloading: Consideration should be given to the connection of the equipment to the power supply circuitry and the effect that any possible overloading of circuits might have on overcurrent protection and power supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.

• Reliable Ground: A reliable ground must be maintained at all times. To ensure this, the rack itself should be grounded. Particular attention should be given to power supply connections other than the direct connections to the branch circuit (i.e. the use of power strips, etc.).

Before installation, remove all blades, power supplies, switches, and management modules. Install these modules after the enclosure is mounted. This rail set fits a rack between 28.5 and 33.7 inches in depth.

Step 1. For each rail, sections are screwed together to keep them immobile during shipping. Release these screws just enough to allow the rails to slide apart.

Step 2. Slide the rails apart far enough to match the depth of the rack. Note the arrow on the rail, which indicates the end that attaches to the front of the rack. Position each rail and secure the front to the front post of the rack with two flathead screws. Then secure the back of each rail to the rear of the rack with two flathead screws.

Step 3. Lift the enclosure and slide it into the rack. Use two roundhead screws on each side of the server to lock it into place.

Warning: The rack stabilizing mechanism must be in place, or the rack must be bolted to the floor before you slide the unit out for servicing. Failure to stabilize the rack can cause the rack to tip over. Always install enclosures at the bottom of the rack first.

Use the following procedure to ensure that power has been removed from the system. This step is necessary when removing or installing non-hot-swap components, such as the only CMM in an enclosure.

Step 1. Use the operating systems to power down all blades.

Step 2. Disconnect all the power cords from the power strip or outlet.

Step 3. Disconnect the power cords from the power supply modules.

MicroBlade modules can be hot-plugged into the enclosure. Use caution when inserting a blade into the enclosure, and do not damage the power connector.

Step 1. Fully open the locking lever on the blade and slowly push it into its bay.

Step 2. When the blade is seated in the bay, push the locking lever into its locked position, making sure the notches in both handles catch the lip of the enclosure.

This section is a brief description of how to get your MicroBlade system up and running.

Step 1. Unpack the components of your MicroBlade system and check the packing list for damaged or missing components.

Step 2. Mount the MicroBlade enclosure in your server rack.

Step 3. Install the power supply modules into the rear of the MicroBlade chassis.

Step 4. Install the CMM module and any other modules into the rear of the MicroBlade chassis.

Step 5. Install networking modules, such as switches.

Step 6. Prepare each blade server with memory, storage drives, add-on cards, etc. Install them into the enclosure.

Step 7. Connect the power cords for your MicroBlade enclosure power supply and plug them into your power source only after you have installed and secured all system components.

Step 8. Power up your MicroBlade system. Check all fault indicator LEDs to be sure all components are operating normally.

Step 9. Install an operating system for each blade module.

The LED status indicator on the power and fan module, located near the locking lever, indicates the module’s operational status.

To prevent compatibility issues, only use components that match the specifications or part numbers.

Step 1. Insert the power module into the empty power bay. Be sure that the orientation is correct. If you inadvertently put a power supply upside down, it can be very difficult to remove.

Step 2. Push unit all the way in until it is firmly seated.

Step 3. Push the locking handle into the closed position until it clicks into position.

Step 4. Move the locking clip away from the socket and reconnect the power cord.

Step 1. Remove the power cord from the power supply unit.

Step 2. Release the locking clip to unlock the power supply module.

Step 3. Pull out the locking handle and remove the unit. To release the handle, squeeze the two metal plates of the handle with your thumb and fingers, and then pull the module out.

If a power module or a fan in a power module fails, the system management software will provide an alert. Replace the power module with another identical one. Note that if a power supply fails, its fans will continue to operate. For this reason, a failed power supply should remain installed in the enclosure until a replacement unit is ready.

If some bays in an enclosure are not filled with power supply modules, they can house similar sized fan modules. If a power supply fails, its fan will continue to operate to provide continuous cooling. For this reason, a failed power supply should remain installed in the enclosure until a replacement unit is ready.

For overheating problems, check that:

• There are no obstructions, such as poorly routed cables.

• All fans are operating normally.

• The ambient room temperature is not too warm.

Also, either of the blade management software utilities can increase the fan speed and maximize system cooling.

The LED status indicators for the MBM-CMM-001 (EOL) module provide visual cues about the system’s status.

Follow anti-static precautions when handling the CMM module.

Installing the Module:

Step 1. Remove the dummy cover from the bay in which you want to place the module.

Step 2. Place the module locking lever in the open position.

Step 3. Slide the module into the module bay until it stops.

Step 4. Push the locking lever to the closed position.

After the module has been installed and the handle locked, it will turn on and a POST test will run to verify it is working properly.

Removing the Module:

Step 1. Pull out the release handle to the open position.

Step 2. Pull the module out of the bay.

Step 3. Replace immediately with another module or with a dummy module cover to maintain airflow integrity.

To access and configure the Chassis Management Module (CMM), you first need to configure its IP settings based on your network environment. The CMM access topology is as follows:

DHCP Access:

• Connect a network cable to the CMM module.

• The system should boot into the default Fail Over mode. The DHCP mode will appear on the CLI mode screen.

• If the system failover and CLI is not active, it will proceed to the default IP access.

• If the CMM cannot enter the default IP, an RJ45/USB cable can be connected from the CMM RJ45 Ethernet LAN Port to a Desktop Host using the USB Port in Serial Port mode with a speed set at 115200. The DHCP IP can be manually set at the same subnet-mask for gateway access at 192.168.100.100.

Default IP Access:

The requirements are a computer with an RJ45 port and an ethernet cable.

Step 1. Connect a network cable to the network port at the CMM. The default IP of the CMM is 192.168.100.100.

Step 2. Configure the connected computer to the same address range, such as 192.168.100.101. The default mode is Fail Over mode. If DHCP fails, the CMM will automatically default to the IP address of the CMM.

Step 1. Go to Start > Control Panel > Network Connections.

Step 2. Right-click on LAN to View Properties.

Step 3. On the General tab page, choose “Internet Protocol (TCP/IP)” and click Properties.

Step 4. Manually configure the IP address of the computer system to be in the same address range as the CMM. For example:

IP address: 192.168.100.101

Subnet Mask: 255.255.255.0

Default Gateway: 192.168.100.1

Once the IP address for the computer system is configured, the CMM can be accessed through the web browser by entering the default IP address 192.168.100.100 of the CMM into the browser’s address bar. The IP address, subnet mask and default gateway of the CMM can then be changed according to the network environment.

To reset the CMM, push the reset button for one minute until the blue LED flashes (quick flash), then release the button. The CMM is reset to the following default values:

• IP Address -> 192.168.100.100

• Gateway Address -> 0.0.0.0

• Subnet Mask -> 255.255.255.0

The firmware for the CMM resides in the module and can be updated with the web-based management utility.

Within the utility, go to the Maintenance > Update Firmware screen. Here you can enter the name of the firmware you want to update or click Browse to select the firmware file. Finish by clicking the Upload button.

Note: This process is not reversible once the firmware is updated, so proceed with caution. It might take a few minutes to complete this procedure.

To log into the Web-based Management Utility:

Step 1. Launch a web browser.

Step 2. In the address field of the browser, enter the IP address that you assigned to the system and hit the <Enter> key.

Step 3. When the browser makes contact with the CMM, enter your user name and password, then click Login.

Note: Supermicro ships standard products with a unique password for the BMC ADMIN user. This password can be found on a label on the motherboard.

The CMM default addresses are:

• IP Address – Reset to 192.168.100.100

• Gateway Address – Reset to 0.0.0.0

• Subnet Mask – Reset to 255.255.255.0

The address can be changed using the Web-based Management Utility.

The network interface card (NIC) ports on the blades are mapped to specific switch slots in the enclosure. The mapping is as follows:

Before working on any equipment, be aware of the hazards involved with electrical circuitry and be familiar with standard practices for preventing accidents.

• Installation: Read the installation instructions before connecting the system to the power source.

• Circuit Breaker: This product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that the protective device is rated not greater than: 250 V, 20 A.

• Power Disconnection: The system must be disconnected from all sources of power and the power cord removed from the power supply module(s) before accessing the chassis interior to install or remove system components. The unit may have redundant power sources; disconnect all power cords before servicing.

• Equipment Installation: Only trained and qualified personnel should be allowed to install, replace, or service this equipment.

• Restricted Area: This unit is intended for installation in restricted access areas. A restricted access area can be accessed only through the use of a special tool, lock and key, or other means of security.

• Backplane Voltage: Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when servicing.

• Hot Swap Fan: Hazardous moving parts. Keep away from moving fan blades. The fans might still be turning when you remove the fan assembly from the chassis. Keep fingers, screwdrivers, and other objects away from the openings in the fan assembly’s housing.
