You can use the Hardware Compatibility Tool to find information about the pluggable transceivers
supported on your Juniper Networks device.
•
Review the maximum distance allowed for each cable. Choose the length of cable based on the
distance between the hardware components being connected. See:

MX2010 Cabinet Airflow Requirements
Before you install the router in a cabinet, you must ensure that ventilation through the cabinet is sufficient
to prevent overheating. Consider the following requirements to when planning for chassis cooling:
•
Ensure that the cool air supply you provide through the cabinet can adequately dissipate the thermal
output of the router.
•
Ensure that the cabinet allows the chassis hot exhaust air to exit from the cabinet without recirculating
into the router. An open cabinet (without a top or doors) that employs hot air exhaust extraction from
the top allows the best airflow through the chassis. If the cabinet contains a top or doors, perforations
in these elements assist with removing the hot air exhaust. For an illustration of chassis airflow, see
Figure 51 on page 128 .
•
Install the router as close as possible to the front of the cabinet so that the cable manager just clears
the inside of the front door. This maximizes the clearance in the rear of the cabinet for critical airflow.
•
Route and dress all cables to minimize the blockage of airflow to and from the chassis.
