Locations — model 561 and 570

Map location codes to hardware.

Mapping physical location codes

Note: The known logical location codes for this unit are listed next to the corresponding physical location in the following information. If you are working with a logical location code for this unit and it is not listed in the following information, contact your next level of support.

For address information, see Addresses – model 561 and 570.

Use the following illustrations to help you map a location code to a position on the server.

Figure 1. Front view of the system unit. P4-D1 and P4–D2 positions are for a 561. The 570 only has the top slot, the P4–D1 location.

Number	Name	Description
1	Display	Displays current status of system startup, or diagnostic information in the event of a hardware problem.
2	Front serial port	Port uses RJ-45 connector. Use to plug in external devices at the front of the system unit.
3	Increment up	Scrolls the information in the display up.
4	Enter	Enter
5	Increment down	Scrolls the information in the display down.
8	System reset button	Resets the system
9	Power LED	Blinking - When connected to the power source (System is in standby mode). Solid - When power button has been pressed. Note: There is approximately a 30-second transition period from the time the power-on button is pressed to when the power LED goes from blinking to on solid. During the transition period, you may observe the blinking intervals speed up.
10	Power-on button	Turns the system power on and off.
11	Service processor reset switch (pinhole)	Service Personnel Use
12	Serial number label	Displays the system serial number

The following table contains location codes for the parts that make up the server.

Attention: After replacing any part on a server or expansion unit, perform Verifying the repair.

Input/output adapter (IOA) assignment rules for i5/OS®

The following table provides information necessary to identify the input/output processor (IOP) to which IOAs are assigned. The left column indicates the bridge set in which IOA assignment is allowed. Use the right column to determine the IOP to which an IOA is assigned. The first position in the list must be an IOP. The remaining positions might be IOPs or IOAs. IOAs are assigned to the first IOP located to their left in the list. Although IOAs can be manually reassigned using system service tools (SST)/dedicated service tools (DST), the IOA assignments return to the default order after each initial program load (IPL).
