Connecting Cables - Huawei CloudEngine 8800 Series Quick Start Manual

8 Connecting Cables

Before You Start
Ground cable.
The switch must be reliably grounded.
Attach the M4 lug to the switch and the M6 lug to the ground point.
Ethernet cable.
Category 5E or higher category Ethernet cables are recommended for GE electrical ports.
Category 6A shielded or higher category Ethernet cables are recommended for 10GE electrical ports.
To protect the switch from lightning, route outdoor cables underground or in steel pipes. Do not route cables aerially.
Optical fiber.
Optical fibers must be used with optical modules. Connectors of fibers and cables must be clean.
Cover idle optical ports with dust plugs. All optical ports on a newly delivered switch are covered with dust plugs.
The bend radius of optical fibers must be larger than 40 mm.
10GE optical ports use SFP/SFP+ optical modules and optical fibers, SFP+ AOC cables, or SFP+ copper cables.
25GE optical ports use SFP/SFP+ optical modules and optical fibers, SFP+ AOC cables, SFP+ copper cables, SFP28 optical
modules and optical fibers, SFP28 AOC cables or SFP28 copper cables.
40GE optical ports use QSFP+ optical modules and optical fibers, QSFP+ AOC cables, or QSFP+ copper cables.
100GE optical ports use QSFP+/QSFP28 optical modules and optical fibers, QSFP+/QSFP28 AOC cables, or QSFP+/QSFP28
copper cables.
Country-specific AC power cable.
Power cables must be more than 10 cm away from signal cables.
The country-specific AC power outlet must have a current rating of 10 A and comply with local standards.
The AC power cable must be locked using a locking strap or bundled to the power module handle using a velcro strap.
C13 straight female to C14 straight male AC power cable.
Choose this type of power cable when the switch uses AC power modules and receives power from an AC PDU, or when it
uses 600 W/1200 W AC&240 V DC power modules and receives power from a 240 V high-voltage DC PDU or power
distribution box.
If a 240 V high-voltage DC power distribution box is used, make OT or cord end terminals for the cable. Cut the C14 straight
male connector off and crimp OT or cord end terminals on the bare wires. Connect the brown wire to a negative terminal on
the DC power distribution box, the blue wire to a positive terminal, and the yellow-green wire to a protection ground.
Notice the positive and negative tags on DC power cables and power terminals.
380 V high-voltage DC power cable.
Choose this type of power cable when the switch uses high-voltage DC power modules and receives power from a 380 V
high-voltage DC power distribution box or frame.
The delivered cable has bare wires on one end, and OT or cord end terminals must be made for them onsite. Connect the
brown wire to the positive pole, blue wire to negative pole, and yellow-green wire to protection ground.
The power cable must be locked using a locking strap or bundled to the power module handle using a velcro strap.
Mini USB port.
The CE8860, CE8861, CE8868, CE8850-64CQ-EI, CE6850HI, CE6855-48T6Q-HI, CE6856-48T6Q-HI, CE6850U-HI and CE6875EI
have a Mini USB port, which provides the same functions as a console port and uses a Mini USB cable.
The Mini USB port and console port cannot be used together. Select either of them according to your needs. When both the
two ports are connected, only the Mini USB port is active.
The USB port is used to transfer upgrade files and configuration files during a USB-based deployment.
