Rack Mounting
The NET5308T-EXP mounts into an industry-standard 19-inch (48 cm) equipment rack. The NET5308T-EXP occupies one rack unit (1.75 inches or
4.5 cm) of vertical rack space. The hardware necessary to mount the NET5308T-EXP into a rack is supplied with the unit.
NOTES:
• If you installed the NET5300B on a desktop, you can also place up to two NET5308T-EXP units on top of the NET5300B. (NET5308T-EXP
units do not include rubber feet.)
• You can mount a NET5300B and up to two NET5308T-EXP units to a wall using the WM5300 wall mount. Refer to the WM5300 Wall Mount
Kit Installation manual (C2663M) for more information.
The rack must meet the following requirements:
• 19-inch (48 cm) EIA-310-D compliant (rear column required to mount the NET5300B in the same rack).
• 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 columns.
• Door systems are acceptable. Front doors must have at least 2 inches (5.1 cm) between the NET5308T-EXP front bezel and the inside of the
door. Rear doors can only be used on rack columns that are more than 26 inches (66 cm) deep.
To install the NET5308T-EXP in a rack:
NOTE: Figure 3 identifies each piece of hardware for this procedure.
1. If chassis mounting brackets are not attached: Attach one chassis mounting bracket to each side of the NET5308T-EXP. Use three
6-32 x 0.25-inch Phillips flat head screws for each bracket.
Figure 6. Attaching Chassis Mounting Brackets
2. Attach one front-mount rail to one rear-mount rail. Make sure the rails are mounted back to back, as shown in Figure 7. Depending on the
rack, use two or three 8-32 x 0.375-inch Phillips truss head screws for each rail set. Leave the screws loose until step 9.
WARNINGS:
• Secure the front and rear screws to the support rails.
• Make sure the NET5308T-EXP is level.
• Slots and openings in the cabinet provide ventilation to prevent the unit from overheating. Do not block 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. Allow at least
one rack unit (1.75 inches or 4.44 cm) of spacing between units.
