Fastening adjacent frames together
Fasten adjacent NEBS 2000 frames together to maximize the use of floor
space between frames with the optional extended cable management
brackets.
Prerequisites
• You must be familiar with “Safety considerations and best practices”
(page 53).
• You must be familiar with the criteria for joining frames as described in
241-1501-205 Passport 15000, 20000 Site Requirements and
Preparation Guide.
• You need kits numbered NTRU0365 and NTHR0370. NTRU0365 keeps
the frames apart the minimum space to allow the optional extended cable
management brackets (kit number NTRU0368 or NTRU0369) to be
mounted on each side between the frames.
• When joining a pair of NEBS 2000 frames, you must either join them
first and position them for levelling together and anchoring, or position
one beside a frame that is already anchored, then level and join the added
one relative to it.
• When adjacent NEBS 2000 frames are fastened together using the frame
joining kits, the space between frames accommodates having the larger
optional extended cable management brackets on each frame and 1 cm
(3/8 in.) between each pair of brackets to enable cabling. Once the frames
are fastened together and installed (anchored and cabled), a frame would
have to be disconnected, moved, and re-installed in order to fit the
extended cable management brackets in between.
Procedure steps
1 Ensure the frames are positioned side by side and touching on the
footprints where they are to be anchored.
2 Remove the packaging from the contents of kits NTRU0365 and
NTHR0370. Keep the contents separate.
3 See the figure “Frame-to-frame joining brackets in kit numbers NTRU0365
and NTHR0370” (page 361). Observe the position of the upper and lower
pairs of brackets. The upper pair of brackets has the same orientation as
