ZTEInstallation Requirement

Site Cleaned: The site, including the floor, should be cleaned, and no evident dust

can be felt by hand on any device. There are no sundries (installation materials

irrelevant to operation, like cartons or remnant cables or wastes left after construction.

All sites need install the same,there is no space between each device ,keep it

like the right side picture showing to us .

For the transmission signal cable to DDF,should be circle well and tie to the

side of the rack ,and make it tied well .

Cable compression modules is not installed and all the bolts should be fasten

well

For power cable go through the Right hole , the grounding cable and the Single

cable go through the left hole ,and every cable should be using the cable tier ,tie

with the cabinet well .

For the redundant fiber cable ,do not reverse the cable like the picture showing

to us.

For the redundant fiber cable ,do like

the picture showing to us, and must be

using the flexible hose for protection .

At the bottom of the RC rack ,the dust seal module should be

block by the silicona materials without leaving any blank holes .

For any RF connector must be FASTEN BY THE SPANNER .

Sliding window in cabinet base,for the power and grounding cables go through to

the back one ,and the signal cables go through an other one ,which depends on

the situation on site . Power & Grounding cable and Signal cable using separate

sliding window .

For any bolts should be fasten well and using the right tools to do the

work ,not only showing in this picture .

Cable route should be go with the CABLE

TRAY.and use tier separate the power and

signal cables ,tie with the cable tray ,and

the cable route should be go straight ,not

like the water waves up and down .

For the redundant cables must be well routed and organized ,and tied with

the cable tray . Careful with the RF cables ,they have the minimum circle

diameter .the minimum diameter for jumper is 120mm.

When there are redundant crimping positions on a ground busbar, one

bolt can only crimp one terminal. When there are inadequate crimping

positions on a ground busbar, one bolt can crimp two terminals at most.

For the redundant jumper cable ,we need deal with like the picture

showing to us ,first of all ,keep 200-300mm straight ,then we can circle

the redundant cables and tie this part nearby .

For waterproofing ,especially the jumper connector ,the Badge wrap

direction should like the picture showing to us ,and the waterproof

badge should make sure the waterproof in a good performance and

also the outlook should smoothly going from the big side to the smoler

ending like the right side of the picture show to us .

Waterprofing standard procedure ( 1+3+3) .

For waterproof,If every output is in use ,we do the standard

procedure( 1+3+3 ),If output is not in use,we also need to do the

waterproof ( 1+1+1 ) to ensure the connector will be carefully protected

for future.

The adjacent racks spacing should be aligned between 2 to 3mm.

Outdoor grounding terminals on grounding bar should be with

anti-corrosion treatment.

When the tie are tightened, the excessive part should be cut off leaving

no burr. When used outdoors, the tie end can be reserved properly

without any burr, but there should not be more than 10 knots.

White ties only used for indoor.Black ties only used for outdoor.

The labels should be pasted about 20mm away from joints. The

adjacent labels should be aligned on the same level with the tails

pointing to the same direction.
