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.
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 SFP Simulation Link or Egston SFP Link through the upper HSSL connector, while on HIL606 this is done via the dedicated SFP connectors, 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.
