IBM SurePorts Point of Sale connections Updated October 31, 2007 Attention Hot plugging of powered USB devices is not supported. USB-only configuration: Figure 6 shows the configuration with only USB connections. HGF ED CBA Figure 6. USB-only configuration (models 7x1) HGF ED CBA Figure 7. USB-only configuration (models 7x2) H, G, F, E, D, and C, B, A All 12-V powered USB ports, except C, which is a 24-V USB port. Note: The letters shown on the USB connectors are used to identify the connector space and the order of connection per card. As an example, for each card, the system first recognizes a device connected to the A USB port before recognizing the device connected to the B USB port. This auto-sensing feature applies to each card; therefore, the system could recognize card 1, USB port B, then C, before recognizing the USB port D on card 2. 3A, 3B IBM cash drawer ports.
