Plan Eight Powered Copper Connections and Cabinet Supply Capacity with Hirschmann BRS42-00089999-TPDY99HHSESXX.X.XX EEC BOBCAT Industrial Ethernet Switch
Hirschmann BRS42-00089999-TPDY99HHSESXX.X.XX identifies Type BRS42-8TX-EEC, part number 942170051. All eight RJ45 interfaces in this configuration are listed as PoE(+) ports and support 10/100/1000BASE-TX. This is an eight-port all-copper arrangement, not a twelve-port switch with four extra SFP uplinks. Include the connections to other network equipment when allocating the available physical ports.
Allocate ports and power together
A network connection consumes a physical port whether it serves a field device, an upstream switch or maintenance equipment. Record those uses first, then assign the powered loads. Review each device requirement against the applicable per-port limits and the 240 W aggregate PoE allowance. A shared maximum does not mean that every connected device can demand the entire budget independently.

Distinguish power-source demand from heat
The exact source lists a maximum of 249 W with 240 W PoE. Much of that energy is supplied onward to connected loads. Use the manufacturer thermal guidance for enclosure calculations and the complete load schedule for source sizing. The voltage reference is 48 V DC for PoE or 54 V DC for PoE+, with two supply inputs.
Review the EEC metal housing
The device is specified at 123 × 140 × 115 mm, IP30 and -40 to +70 °C. Check cabling and terminal clearances using the current installation drawing. Retain the complete code, port map and load schedule for future maintenance and quotation requests.
Prepare a configuration-specific enquiry
Ask HKXY to quote the specified device reference with quantity and destination. For replacement work, include a device-label photograph and identify retained components. Confirm the supply scope, documentation and delivery timing before purchase.
