HW setup

Instructions on how to setup a parallel connection of hardware devices.

Connecting devices

Devices are connected using either:

  • HIL404: 2 SFP+ ports on the back plate of the devices and standard SFP+ optic module with cables.
  • HIL602+/HIL604: 2 PCIe 4X connectors on the back plate of the devices and standard PCIe 4X v2 or better cables.
  • HIL606: 2 QSFP28 ports on the back plate of the devices and standard QSFP28 optic module with optic cables or passive direct attach copper QSFP28 cable.
  • Recommended cable part numbers are given in Table 1.

Connection mode for HIL602+ and HIL604 devices

HIL602+ and HIL604 devices should be connected over Daisy chain to establish a Link.

Daisy chaining is ensured by connecting TXN -> RXN and TXP -> RXP connectors between devices until the ring is closed.

Figure 1. Example of a 3-unit HIL602+/604 setup
Note: In order to ensure proper link operation, use only cables recommended by Typhoon HIL.

Connection mode for HIL404 and HIL606 devices

HIL404 and HIL606 devices should be connected point to point from the HSSL1 and HSSL2 connectors on one device to another device. Figure 2 represents one way of connecting devices. HIL device 1 is connected to HIL device 2, HIL device 2 to HIL device 3, and so on. Lastly, HIL device 1 can be connected to the HIL device 4, to minimize transfer delay between HIL devices.

Additionally, connections to third-party devices on HIL404 can be done over the SFP Simulation Link protocol through the upper HSSL connector, while on HIL606 this is done via the dedicated SFP connector, as shown in Figure 3.

Device IDs

Device ID numbers in a multi-HIL configuration should be continuous starting from zero. For example, in a 2-unit system: IDs should be 0 and 1; in a 3-unit system: 0, 1 and 2; and so on. The Device ID number is completely independent of the device position in the ring.

Note: Device ID number is set using the rotary switch on the back plate of the device.
