Preparing for installation
The H3C S6850 Switch Series and S9850 Switch Series are high-density intelligent 100G access
switches with powerful hardware forwarding capacity and abundant data center features. They are
developed for data centers and high-end campus networks.
The H3C S6850 Switch Series includes the following models:
•
S6850-56HF
•
S6850-2C
The H3C S9850 Switch Series includes the following models:
•
S9850-4C
•
S9850-32H
The switch supports the following ports and FRUs:
•
100G QSFP28 ports, 40G QSFP+ ports, 25GE SFP28 ports, and 10G SFP+ ports.
•
Two 1G management Ethernet ports (one fiber port and one copper port).
•
Removable fan trays in redundancy mode and flexible airflows.
•
Removable power modules in redundancy mode.
Safety recommendations
To avoid any equipment damage or bodily injury caused by incorrect use, read the following safety
recommendations before installation. Note that the recommendations do not cover every possible
hazardous condition.
•
Before cleaning the switch, remove all power cords from the switch. Do not clean the switch
with wet cloth or liquid.
•
Do not place the switch near water or in a damp environment. Prevent water or moisture from
entering the switch chassis.
•
Do not place the switch on an unstable case or desk. The switch might be severely damaged in
case of a fall.
•
Ensure good ventilation of the equipment room and keep the air inlet and outlet vents of the
switch free of obstruction.
•
Connect the yellow-green protection grounding cable before power-on.
•
Make sure the operating voltage is in the required range.
•
To avoid electrical shocks, do not open the chassis while the switch is operating or when the
switch is just powered off.
•
When replacing field replaceable units (FRUs), including power modules and fan trays, wear an
ESD wrist strap to avoid damaging the units.
Examining the installation site
The switch must be used indoors.
Mount your switch in a rack and verify the following items:
•
Adequate clearance is reserved at the air inlet and outlet vents for ventilation.
•
The rack has a good ventilation system.
