Metal-Housing Cabinet Planning and EEC Optical Module Checks for Hirschmann BRS40-0020OOOO-TTDY99HHSESXX.X.XX Twenty-Port BOBCAT Managed Switch
Hirschmann BRS40-0020OOOO-TTDY99HHSESXX.X.XX identifies Type BRS40-16TX/4SFP-EEC, part number 942170066, in the Hirschmann BOBCAT range. This EEC version places sixteen Gigabit-capable RJ45 interfaces and four 100/1000 Mbit/s SFP slots in a metal housing. Its operating range is -40 to +70 °C. Those characteristics are relevant to cabinet selection, but they do not automatically qualify every connected component for the same temperature range or establish compatibility with an existing installation.

Use the metal-version mechanical reference
The source lists enclosure dimensions of 123 × 140 × 115 mm. Review the mounting drawing and installation clearances for this exact configuration, particularly when replacing a standard-temperature PC-ABS version. Leave access to the terminal block, fiber connectors and removable modules. Matching port count should not be used as evidence that the physical installation envelope is unchanged.
Check the optics across the required temperature range
Each proposed SFP needs its own compatibility and temperature check. Record the optical type, wavelength, connector and link-loss allowance alongside the intended remote interface. An extended-temperature switch does not raise the operating limit of a separately supplied module. Confirm the complete assembly before specifying an environmental acceptance condition for the network connection.

Retain the copper and fiber distinction
The sixteen copper ports support 10/100/1000BASE-TX; the four SFP positions support 100/1000 Mbit/s. Do not replace this with a generic claim of 2.5-Gigabit uplinks taken from another family configuration. Network design should use the speeds and media of the ordered code, together with the actual modules and endpoint settings selected for the project.
Information for your purchase request
Provide HKXY with the full EEC code, quantity, cabinet environment and SFP requirements. Include mounting constraints or an existing device label where relevant, and confirm documentation and delivery scope before ordering.
