Acx5400 Grounding Cable And Lug Specifications - Juniper ACX5448-D Hardware Manual

Maintain ambient airflow for normal router operation. If the airflow is blocked or restricted, or if the
intake air is too warm, the router might overheat, leading to the router temperature monitor shutting
down the device to protect the hardware components.
Table 30 on page 68 provides the required environmental conditions for normal router operation.

ACX5400 Grounding Cable and Lug Specifications

For installations that require a separate grounding conductor to the chassis, you must ground the router
properly before connecting power to ensure proper operation and to meet safety and electromagnetic
interference (EMI) requirements. To ground an ACX5400 router, connect a grounding cable to earth ground
and then attach it to the chassis grounding points.
