RACK MOUNTING
The NSM5200 mounts into an industry-standard 19-inch (48 cm) equipment rack. The NSM5200 occupies three rack units (5.25 in. or 13.3 cm) of
vertical rack space. The hardware necessary to mount the NSM5200 into a rack is supplied with the unit.
The rack must meet the following requirements:
• 19-inch (48 cm) EIA-310-D compliant (rear column required)
• Rack column depth: 24 to 30 inches (61 to 76 cm)
• Column mounting hole provisions: 10-32 UNF-2B threaded holes or square window holes on front and rear columns
• Door systems are acceptable. Front doors must have at least 2 inches (5.1 cm) between the NSM5200 front bezel and the inside of the door.
Rear doors may only be used on rack columns that are more than 26 inches (66 cm) deep.
To install the NSM5200 in a rack:
NOTE: Figure 3 on page 11 identifies each piece of hardware for this procedure.
Figure 6. Fastening Mounting Brackets to Chassis
1. If chassis mounting brackets are not attached: Attach one mounting bracket to each side of the NSM5200. Use six 10-32 x 0.25-inch Phillips
pan head screws for each bracket. Attach the brackets so that the tapered ends are positioned toward the rear of the unit.
2. Remove the rubber feet from the underside of the unit if they are attached.
WARNINGS:
• Secure the front and rear screws to the support rails.
• Make sure the NSM5200 is level.
• Slots and openings in the cabinet provide ventilation to prevent the unit from overheating. Do not blo ck these openings. Never place
the unit near or over a radiator or heat register. When placing the unit in a rack, be sure to provide proper ventilation.
• Four of the six redundant fans are located in the upper-middle portion of the unit. If the unit must be pulled out to replace a fan, make
sure that all cables connected to the unit have sufficient length to avoid being disconnected.
