Cabinet Layout and Temperature-Graded Optical Selection for Hirschmann BRS40-0024OOOO-TTDY99HHSESXX.X.XX Twenty-Four-Port EEC Managed Ethernet Switch
Hirschmann BRS40-0024OOOO-TTDY99HHSESXX.X.XX identifies Type BRS40-20TX/4SFP-EEC, part number 942170068, in the Hirschmann BOBCAT range. This EEC configuration combines twenty Gigabit-capable copper ports and four 100/1000 Mbit/s SFP slots in a metal enclosure. The -40 to +70 °C operating range makes it a specific environmental selection within the BOBCAT family. The switch, fitted optics and cabinet arrangement should be reviewed together rather than treating the environmental suffix as a complete installation specification.
Plan the metal enclosure in the actual cabinet
The published dimensions are 123 × 140 × 115 mm. Compare the current mounting drawing with the available rail space and leave room for a heavily populated front panel. Optical patch leads, RJ45 plugs and terminal access can require more space than the housing alone. Do not assume identical packaging from the same port count on a standard-temperature unit.
Match each optical module to the route and environment
Confirm that the proposed SFP is supported by this switch and suitable for the required temperature. Then assess fiber type, wavelength, connector, route attenuation and the remote interface. The port specification is 100/1000 Mbit/s; it does not establish 2.5-Gigabit operation or a universal transmission distance. Record the chosen module reference in the final equipment list.

What should be retained for an eventual replacement?
Keep the complete switch code, the installed module list, the port map and the approved network settings. Include the required environmental range and any mechanical constraints in the spare-parts record. These details let a future quotation be reviewed against the real installation instead of relying on a generic twenty-four-port description or a shared stock photograph.
Configuration-specific quotation
Request the exact EEC switch from HKXY with quantity, destination and a defined optical scope. Identify enclosure constraints and required documents, and confirm the supplied modules and delivery schedule in the written quotation.
Technical reference: Belden catalog for BRS40-20TX/4SFP-EEC. Confirm the current documentation and supplied revision before final engineering approval.
