hub, but can also be used for the chassis' front panel USB, auxiliary ports that
mount in the card slots, and certain devices that directly connect to the header.
The USB 3.1 Header on the H370 Stinger is a shielded USB 3.1 Header and
supports up to 10Gb/s with USB3.1 Gen2.
This USB 3.1 Header has a power limit of 3000ma (3A) @ 5V.
18. Rear Panel IO (Figure 2)
This is the section referred to as the I/O Hub. This panel contains the
hardwired USB, Sound, and Ethernet connections. Please see Page 11 for a
component level breakdown.
* There are two numeric references for PCIe: one is mechanical, which is the actual slot-
length footprint, and the second is electrical, which is a reference of how many PCIe
lanes are routed to the slot.
Because PCI Express is designed to be a universal architecture, you can install x1 cards,
such as sound cards or USB controllers into an x16 slot. Many types of cards can use
different amounts of PCIe lanes, while some applications use only certain parts of a
card, such as compute apps that allow a card to run off a single PCIe lane. This is why
there are x16 mechanical slots with an x1 electrical PCIe lane. Using the entire length of
a PCIe slot is unnecessary, nor does it cause an adverse effect to use a shorter form-
factor bus card in a slot that physically can hold a larger form-factor bus card.
