Installing and removing a network cable
CAUTION:
•
Make sure the two modular ends of a network cable are compatible with the ports into which
they will be inserted.
•
Do not touch the golden plating on the two modular ends of the network cable during the
installation or removal process.
•
To avoid network cable damage and signal loss, do not strain or tangle a network cable.
•
Before inserting a modular end of a network cable into a port, make sure the module aligns with
the port correctly.
A QSFP+ to 4 × SFP+ network cable has a 40G QSFP+ module at one end and four SFP+
transceiver modules at the other end. A QSFP28 to 4 × SFP28 network cable has a 100G QSFP28
module at one end and four 25G SFP28 transceiver modules at the other end.
The installation and removal procedure is the same for H3C network cables. The following
procedure uses a QSFP+ network cable as an example.
Installation procedure
1.
Remove the dust plug from the target fiber port.
2.
As shown in
, correctly orient the modular end of the network cable. Align the module
with the fiber port and push it gently into the port until you feel it snaps into place.
Transceiver modules and fiber ports have disorientation rejection structures. If you cannot
insert a transceiver module easily into a port, remove and reorient the transceiver module.

Removal procedure
1.
Putting your forefinger into the pull latch, carefully pull the network cable straight out of the
fiber port.
As shown in
, if you use force at an angle, you can hardly pull the network cable out
and the network cable or fiber port might be damaged.
