3. FUNCTIONAL DESCRIPTION
Port Description
- This Ethernet port is not functional.
0...18 General purpose, full-duplex RJ45 Ethernet copper ports configurable for 100Base-TX.
19...24 General purpose, full-duplex RJ45 Ethernet copper ports configurable for
100/1000Base-T.
19...24 General purpose SFP ports configurable for 1000Base-X, suitable to operate 1000Base-
X-compliant SFP modules.
Table 1: Ports of the TTE-Switch Lab Space
NOTE
Each of the 1000Base Ethernet ports can either be used as RJ45 port or as SFP port, but not as an RJ45
and SFP port at the same time.
NOTE
Hot-plugging SFP modules (i.e., inserting a module during runtime) is only supported if the switch is con-
figured to use the 1000Base-X ports. Otherwise, a reset is required to configure SFP modules.
Port LED Description
The Link LED illuminates steadily when a link is established with the connected internal
end system.
The Activity LED flashes when communication activity is detected (frame transmission
or reception).
No link and no activity detected.

3.2.2 Debug and Maintenance Interfaces
The TTE-Switch Lab Space interfaces described in this section are not meant for static cable installations
and serve for debug and maintenance purposes only.
3.2.2.1 GPIO Interface
The GPIO interface is used to access the GPIO interface of the TTE-Controller HiRel. This interface is
used for general purposes as can be seen in Table 3 on the next page.
Figure 6: GPIO
The GPIO pins (see Figure 6 on this page) are used to select which configuration
will be loaded at boot.
When using a jumper between the pins 9 and 10, the default con-
figuration is loaded. If no jumper is used, the user configuration is
loaded.
Pin No. Feature Description Default
1 IRQ0 Internal end system external trigger 0. Output high
3 IRQ1 Internal end system external trigger 1. Output high
5 IRQ2 Integration cycle start interrupt. Output high
7 NA NA Input
