Connecting Power to SBC 7000 Series and Powering On

After installing the 

chassis to a rack and attaching necessary cables, you are now ready to install power and ground cables and apply power to the SBC. The  is capable of dual redundant AC or DC power.

The standard

is shipped with two power supplies. Please contact your sales representative for more information.

Grounding SBC 7000 Chassis

The following procedure explains how to ground the

to local earth using a 7/16 inch wrench:

1. Locate the chassis grounding studs on the back of the chassis.

2. Attach the two hole chassis ground lug PN 501-00526 to

3. Secure the other end of the grounding cable to the earth ground in the building. You can secure the grounding cable to a proper grounding point on the rack, as long as the rack is properly grounded to the earth ground in the building.

Routing the Power Cables

Route the power cables so that the left power supply cables connect from left side and the right power supply cables connect from right. This prevents one power supply cable from getting in the way of the other one in case it needs to be removed individually.

Connecting to AC Power Source and Powering On

The following procedure explains how to connect to the AC power and powering on the switch:

1. For each AC power supply, insert the supplied AC power cord's female connector to the power supply AC receptacle at the rear of the chassis (shown in the following figure).

3. Turn on your local AC power source.

Disconnecting from AC Power Source

The following procedure explains how to disconnect from your local AC power source:

1. Perform a graceful shutdown of the

   system through BMC.
2. Turn off your local AC power source.
3. Remove the power cord.

Connecting to DC Power Source and Powering On

The following procedure explains how to connect an 

power supply to the DC Power and power on the switch. If two power supplies are installed, both need to be connected to a power source before powering on the system.

1. Remove the clear plastic terminal cover and set it aside. Check the chassis ground is connected to the 2-post terminal lug next to the power supply bay. 

2. Connect ground cable (green) to the lug to the right of the DC power terminal posts as shown in the below figure:

3. Use a voltmeter to verify that no voltage is present on DC input power cables.
4. Attach the DC return cable (black) to the "+" terminal.
5. Attach the -48V cable (red) to the "-" terminal.
6. Reattach the clear plastic terminal cover.

7. If applicable, attach the other end of the supplied DC power cables to DC power source.

   Do not apply DC power to the DC Power supply prior to hot-inserting the supply into the chassis.

8. Turn on DC power source.

Disconnecting from DC Power Source

The following procedure explains how to disconnect DC power from 

series chassis:

1. Perform a graceful shutdown of the 
   Unable to show "metadata-from": No such page "_space_variables"
   system through BMC.
2. Turn off the local DC power source.
3. Remove the clear plastic terminal cover and set it aside.
4. Remove the DC power cables from the terminals, and re-attach the nuts.
5. Remove the ground cable from the power supply, and re-attach the nut.

Removing the Power Supply

To remove the AC or DC power supply from the chassis, perform the following steps:

1. Push the green or black integrated lever towards your left to disengage the power supply module.
2. Pull the power supply out of the power supply slot.
