Cooling Options

Great Lakes EN Cooling Options

Filler panels and brush grommet kits to prevent bypass airflow within the enclosure

Great Lakes Baffle Kits create proper airflow for switches, and side-to-side airflow equipment, as suggested by manufactures such as Cisco Nexus or Catalyst Switches. Cool air is channeled into the equipment along the right side and exhaust air is directed out along the left side. Kits are tool-less and easily attach to rails outside of EIA mounting profile.

Ganged Enclosure

2x Great Lakes EN Ganged Together

EN Enclosures are designed so that the front doors open to the left or right. When two enclosures are ganged together, doors can open in opposite directions, creating a large space where cables are easily accessible and able to be routed up, down, or to the next enclosure.

Power & Grounding

  • PDU mounting brackets that allow button mounting of major industry PDUs
  • Optional zero RMU mounting brackets allow vertical mounting of 19" power strips
  • Grounding kit with quick disconnect wires are included with each EN configuration

Cable Management "Fingers"

  • Fingers (made up of 7 RMU sections) are pre-installed on all rails and align with RMUs for clean cable pathways
  • Additional kits (or single finger sections) are available

Additional Cable Management

  • Large top knockouts for top cable access
  • Additional kits (or single finger sections) are available

Optional Accessories include:

  • 19" cable organizers
  • Overhead cable accessories, including troughs and ladder rack brackets
  • Horizontal cable manager for front to rear cables
