Hirschmann BRS30-20042T2T-TTDY99HHSESXX.X.XX Twenty-Four-Port EEC Copper Network Procurement with Metal Housing and Explicit Mixed-Speed Port Allocation
Hirschmann BRS30-20042T2T-TTDY99HHSESXX.X.XX is the BRS30-24TX-EEC configuration in the Hirschmann BOBCAT range. A metal housing and a -40 to +70 °C operating range distinguish this EEC copper configuration from the standard-temperature selection. Twenty Fast Ethernet RJ45 connections and four Gigabit-capable RJ45 connections provide the twenty-four-port layout; the exact ordering code should stay attached to the environmental and network requirements.
Keep environmental and traffic requirements separate
The EEC rating addresses operating temperature, while the port list defines Ethernet connection speeds. Evaluate both against the intended installation. A temperature-qualified switch can still have the wrong interface mix for the network, and four Gigabit-capable ports do not turn the remaining twenty Fast Ethernet connections into Gigabit interfaces.
Request the precise installation drawing
When rail space is restricted or an installed switch is being replaced, obtain the current drawing for this complete configuration. Do not carry over dimensions from adjacent catalog entries. Check terminal accessibility, connector clearance and cable routing against the actual enclosure layout before the installation design is released.

How should a maintenance purchase be prepared?
Retain the existing configuration, port labels and a clear image of the device nameplate. Compare the proposed replacement code, software requirements and operating conditions with the accepted equipment specification. Any change should be identified and reviewed before the purchase order rather than discovered during a scheduled network shutdown.
Give HKXY the complete EEC copper-network request
Provide quantity, destination and the required delivery schedule, together with cabinet conditions and documentation requirements. If physical fit is critical, request the exact mechanical drawing and identify the constraint explicitly so it can be resolved before ordering.
