For Your Safety
Your new Kontron product was developed and tested carefully to provide all features necessary to ensure its
compliance with electrical safety requirements. It was also designed for a long fault-free life. However, the life
expectancy of your product can be drastically reduced by improper treatment during unpacking and installation.
Therefore, in the interest of your own safety and of the correct operation of your new Kontron product, you are
requested to conform with the following guidelines.
High Voltage Safety Instructions
As a precaution, in case of danger, the power connector is the product’s main disconnect device and must be easily
accessible.
Warning!
The power connector is the product’s main disconnect device and must be easily
accessible.
Warning!
All operations on this device must be carried out by sufficiently skilled personnel only.
Caution, Electric Shock!
Before installing a not hot-swappable Kontron product into a system always ensure that
your mains power is switched off. This applies also to the installation of piggybacks. Serious
electrical shock hazards can exist during all installation, repair and maintenance operations
with this product. Therefore, always unplug the power cable and any other cables which
provide external voltages before performing work.
Earth ground connection to vehicle’s chassis or a central grounding point shall remain
connected.
The earth ground cable shall be the last disconnected or the first connected during
operations of cabling.
Special Handling and Unpacking Instructions
ESD Sensitive Device!
Electronic boards and their components are sensitive to static electricity. Therefore, care
must be taken during all handling operations and inspections of this product, in order to
ensure product integrity at all times
Do not handle this product out of its protective enclosure while it is not used for operational purposes unless it is
otherwise protected.
Whenever possible, unpack or pack this product only at EOS/ESD safe work stations. Where a safe work station is not
guaranteed, it is important for the user to be electrically discharged before touching the product with his/her hands
or tools. This is most easily done by touching a metal part of your system housing.
It is particularly important to observe standard anti-static precautions when changing piggybacks, ROM devices,
jumper settings etc. If the product contains batteries for RTC or memory backup, ensure that the board is not placed
on conductive surfaces, including anti-static plastics or sponges. They can cause short circuits and damage the
batteries or conductive circuits on the board.

1/ Introduction
The RES2404-PTP-PoE is a standalone Rugged Ethernet Switch (RES) family, supporting 24 Gigabit Ethernet Ports
and four 10 Gigabit Ethernet Ports. It is specifically designed for working reliably under harsh environmental
conditions.
There are two different RES2404-PTP-PoE product options (see table below), each using the Ethernet Switch Core
Module ESC2404-PTP.
Table 1: Product Variants
Product Name Description
RES2404-AC-PTP-PoE 24x GbE ports, 4x 10GbE ports, PTP module, PoE+, 300 W power supply
RES2404-AC-PTP 24x GbE ports, 4x 10GbE ports, PTP module, no PoE+, 100 W power supply
Each switch interface is able to run at full wire speed regardless of the status of other interfaces. The switching fabric
does not limit the throughput of the interfaces. The product is defined as non-blocking switch fabric with line rate
switching. The number of interfaces and the corresponding speed define the maximum bandwidth. For 24 x GbE ports
+ 4 x 10GbE ports operating at full duplex rate, the resulting bandwidth is 64Gbit/sec (24Gbit/sec + 40Gbit/sec).
The key features of the Rugged Ethernet Switch are:
1U System
24 Ports 10/100/1000Base-T RJ45
four 10 Gigabit Ethernet Ports
Power Suppy AC 110/230 with 100 W without PoE or 300 W PoE version
10/100/1000Base-T and RS232 for switch management
Rotary Dip Switch for configuration of 8bit Carrier ID (CID)
Designed to meet military and transportation norms
Temperature range from -20°C to +50°C (RES2404-AC-PTP)
Temperature range from -20°C to +55°C (RES2404-AC-PTP-PoE)

Signal Description
MDI[0]+ / MDI[0]- In MDI mode, this is the first pair in 1000Base-T, i.e. the BI_DA+/- pair,
and is the transmit pair in 10Base-T and 100Base-TX.
In MDI crossover mode, this pair acts as the BI_DB+/- pair,
and is the receive pair in 10Base-T and 100Base-TX.
MDI[1]+ / MDI[1]- In MDI mode, this is the second pair in 1000Base-T, i.e. the BI_DB+/- pair,
and is the receive pair in 10Base-T and 100Base-TX.
In MDI crossover mode, this pair acts as the BI_DA+/- pair,
and is the transmit pair in 10Base-T and 100Base-TX.
MDI[2]+ / MDI[2]- In MDI mode, this is the third pair in 1000Base-T, i.e. the BI_DC+/- pair.
In MDI crossover mode, this pair acts as the BI_DD+/- pair.
MDI[3]+ / MDI[3]- In MDI mode, this is the fourth pair in 1000Base-T, i.e. the BI_DD+/- pair.
In MDI crossover mode, this pair acts as the BI_DC+/- pair.

2.2.2. Small Form-Factor Pluggable (SFP+) connector for 10GbE
The RES2404-PTP-POE supports four SFP+ fabric switch uplinks to the front panel. The SFP+ uplink ports are
according the Small Form-factor Pluggable (SFP) Transceiver Multi-Source Agreement (MSA), Sept. 14th, 2000. The
connector fits for GbE/10GbE Copper/Fiber and Direct Attached Copper Cables.
