Unused connectors

CEC enclosure control panel

Table 1 describes the unused connector shown in Figure 1.

Table 1. Unused connectors for the CEC enclosure control panel
Index	Unused Connector	Quantity (Minimum/Maximum)	Description
1	Ethernet	2	The network connection is through the HMC. The RJ45 network connectors on the two 9117's are not used by the DS8000.

Table 2 describes the unused connectors in Figure 2.

Table 2. Unused connectors - front CEC enclosure
Index	Unused Connector	Quantity (Minimum/Maximum)	Description
1, 2	System processor card expansion bus	2/4	The front system bus connectors are used to attach multiple 9117's on the same bus to increase the number of processors. The 9117's in the DS8000 are used for redundancy only and will never be connected in parallel. Use of these connectors is not supported by the DS8000 and will cause system failures if connected.

Table 3 describes the unused connectors shown in Figure 3.

Table 3. Unused connectors - rear CEC enclosure
Index	Unused Connector	Quantity (Minimum/Maximum)	Description
1, 2, 3, 4, 5, 6	Ethernet port	0/4	The DS8000 supports Ethernet network adapters for system partitioning, but only in a LPAR system configuration.
7, 8, 9, 10	USB/serial port	4/4	The 9117's are redundant controllers for the DS8000. The USB and serial ports of the 9117's are not supported in the DS8000 operating system and will cause system errors if connected.
11	External system bus	2/2	The front system bus connectors are used to attach multiple 9117's on the same bus to increase the number of processors. The 9117's in the DS8000 are used for redundancy only and will never be connected in parallel. Use of these connectors is not supported by the DS8000 and will cause system failures if connected.

Table 4 describes the unused connectors shown in Figure 5.

Table 4. Unused connectors - I/O enclosure, device adapter card
Index	Unused Connector	Quantity (Minimum/Maximum)	Description
1, 2, 3, 4	Fibre channel arbitrated loop port	4/4	The device adapter (DA) cards are plugged in slot 3 or 6 of the I/O enclosure Figure 4. The number of DA cards varies with the installed features. DA card ports 1/2 and 3/4 are each an FC-AL loop. Both ports for a loop will have cables if there are storage enclosures installed using those ports. Both ports for a loop can also be unused and available for potential future use. It is not necessary to externally terminate unused ports.

Table 5 describes the unused connectors in Figure 6.

Table 5. Unused connectors - I/O enclosure, Fibre Channel host card
Index	Unused Connector	Quantity (Minimum/Maximum)	Description
1, 2	Fibre channel host connection port	0/64	The Fibre Channel host adapter cards are plugged in slot 1, 2, 4, or 5 of the I/O enclosure Figure 4. The number of Fibre Channel host cards varies with the installed features. The customer provides Fibre Channel host cables and determines how many ports to use. It is not necessary to externally terminate unused ports.

Table 6 describes the unused connectors in Figure 7.

Table 6. Unused connectors - x336 (front)
Index	Unused Connector	Quantity (Minimum/Maximum)	Description
1	USB port	2	DS8000 has one network connection. Cable entry to the DS8000 is from the rear of the system. Therefore, the network connection is to the rear of the HMC and this connector is not used.

Table 7 describes the unused connectors in Figure 8.

Table 7. Unused connectors - x336 (rear)
Index	Unused Connector	Quantity (Minimum/Maximum)	Description
1	Ethernet port	2	The PCI Ethernet card has two ports; only one is needed for the DS8000.
2, 4, 5, 6, 7	USB/Modem phone port	2	The rear Ethernet, firewire, serial, RS232, mouse, and keyboard of the HMC are unsupported in the application of the 8837 and not supported by DS8000 system hardware.
3	Proprietary outgoing multi-drop keyboard/display port	2	Not used for DS8000. The incoming port is used, but since there are no multiple display connections, the outbound port is not needed.

Table 8 describes the unused connectors in Figure 9.

Table 8. Unused connectors - RPC card
Index	Unused Connector	Quantity (Minimum/Maximum)	Description
1	Rack power control port	4	Only used if optional expansion racks 1 or 2 are installed.
2, 3	Rack power control port	10	Reserved for potential future use. A system error may occur if cables are connected to any of these ports under the current configuration.

Table 9 describes the unused connectors in Figure 10.

Table 9. Unused connectors - rack ID card
Index	Unused Connector	Quantity (Minimum/Maximum)	Description
1	Rack identify signals	4	Cabled on a base rack (first rack). Not used on an expansion rack.

Table 10 describes the unused connectors in Figure 11.

Table 10. Unused connectors - fan sense card
Index	Unused Connector	Quantity (Minimum/Maximum)	Description
1	Fan sense control signals port from storage enclosures	8	Not used on a base rack (first rack). Ports are used in an expansion rack depending on how many optional storage enclosures are installed in the bottom half of the rack.

Table 11 describes the unused connectors in Figure 12.

Table 11. Unused connectors - primary power supply
Index	Unused Connector	Quantity (Minimum/Maximum)	Description
1	Signals to rack ID card	2	Cables are connected for expansion racks only.

Table 12 describes the unused connectors in Figure 13.

Table 12. Unused connectors - storage enclosure
Index	Unused Connector	Quantity (Minimum/Maximum)	Description
1	Card build test port	2 per storage enclosure	Used for card build test or debug port.
2, 3	Fibre channel arbitrated loop	4 per storage enclosure	The Fibre Channel in the storage facility is configured in strings. The ends of the strings will always be open. Connecting cables will cause system errors.

Table 13 describes the unused connectors in Figure 14.

Table 13. Unused connectors - Ethernet switch
Index	Unused Connector	Quantity (Minimum/Maximum)	Description
1, 2, 3, 4, 5, 6, 7, 8	Ethernet port	12	Reserved for potential future use. A system error may occur if cables are connected to any of these ports under the current configuration.
