Table 19: Cabinet Requirements and Specifications
Guideline
Cabinet
Requirement
You can mount the JRR200 route reflector in a cabinet that contains a 19-in.
rack as defined in Cabinets, Racks, Panels, and Associated Equipment
(document number EIA-310–D) published by the Electronics Industry
Association (
http://www.ecianow.org/standards-practices/standards/ ).
Cabinet size
•
The outer edges of the mounting brackets extend the width of the chassis
to 19 in. (48.2 cm).
• The minimum total clearance inside the cabinet is 30 in. (76.2 cm) between
the inside of the front door and the inside of the rear door.
Cabinet
clearance
When you mount JRR200 route reflector in a cabinet, you must ensure that
ventilation through the cabinet is sufficient to prevent overheating.
• Install the JRR200 route reflector as close as possible to the front of the
cabinet so that the cable management system clears the inside of the
front door. Installing the chassis close to the front of the cabinet maximizes
the clearance in the rear of the cabinet for critical airflow.
• Ensure adequate cool air supply to dissipate the thermal output of the
JRR200 route reflector.
• Route and dress all cables to minimize the blockage of airflow to and from
the chassis.
• A cabinet larger than the minimum required provides better airflow and
reduces the chance of overheating.

Pluggable Transceivers Supported on JRR200 Route Reflector
The ports on the JRR200 Route Reflector supports SFP+ transceivers. You can find the
list of transceivers supported on JRR200 route reflector and information about those
transceivers at the
The Hardware Compatibility Tool
.
NOTE: We recommend that you use only optical transceivers and optical
connectors purchased from Juniper Networks with your Juniper Networks
device.
CAUTION: If you face a problem running a Juniper Networks device that uses
a third-party optic or cable, the Juniper Networks Technical Assistance Center
(JTAC) can help you diagnose the source of the problem. Your JTAC engineer
might recommend that you check the third-party optic or cable and potentially
replace it with an equivalent Juniper Networks optic or cable that is qualified
for the device.
