If you do not use the bases provided by Huawei, choose bases of appropriate specifications
for various cabinets to ensure the matching between bases and cabinets. For detailed

If you do not use the bases provided by Huawei, design the bearing requirements for bases
according to the service plan.

The bearing capacity of each base is 2 tons or more.
Assume that each row of cabinets is configured with N bases:
− If N is less than 5, you can install all the bases at a time. After installation, check
that the total length of each row of bases is the sum of nominal widths of all bases
(tolerance –3 mm to 0 mm).
− When N is greater than or equal to 5, you are advised to install five bases at a time.
After installation, check that the total length of each row of bases is the sum of
nominal widths of all bases (tolerance –3 mm to 0 mm). After installing five bases,
check whether the total length of the five bases and the difference between their
diagonal lengths meet the requirements, as shown in Figure 3-42. If the difference
meets the requirements, tighten the bolts and continue to install next five bases. If
the difference does not meet the requirements, adjust the bases to meet the
requirements before tightening the bolts to prevent supports secured in a
parallelogram or trapezoid shape.
To ensure accurate locations, you are advised to determine base locations using a laser
locator before installing bases.
