1 Product model and technical
specifications
Product model
The H3C S9820-64H switch is a high-density intelligent 100G switch developed for data center and
high-end campus networks, providing powerful hardware forwarding capacity and abundant data
center features.
The switch provides the following ports and removable components:
•
100G QSFP28 ports.
•
Two 1G management Ethernet ports (one fiber port and one copper port).
•
Removable fan trays in redundancy mode. By using different fan trays, you can change the
airflow direction of the chassis to adapt to ventilation needs.
•
Removable power supplies in redundancy mode.
NOTE:
The
S9820-64H switch model is available with multiple product codes. To
identify the product code
of your switch
, use the product barcode on its rear panel. The S9820-64H
switch model is available
with the LS
-9820-64H or LS-9820-64H-H1 product code. If the switch is referred to as the
S
9820-64H switch, the information applies to the S9820-64H switch with either of the codes. If the
switch is referred to as the S
9820-64H (LS-9820-64H) or LS-9820-64H switch, the information
applies only to the S9820-64H switch with the LS-9820-64H product code.

Power supplies
WARNING
!
When the switch has power
supplies in redundancy, you can replace a power supply without
powering off the switch. To avoid device damage and personal injury, make sure the power
supply
is
powered off before you replace it.
The switch can operate correctly with two power supplies. You can install three or four power
supplies on the switch for 2+1 or 2+2 redundancy, respectively.
You can install both LSVM1AC650 and LSVM1DC650 power supplies on the switch.

USB port
The switch has one OHCI-compliant USB 2.0 port that can upload and download data at a rate up to
480 Mbps. You can use this USB port to access the file system on the Flash of the switch, for
example, to upload or download application and configuration files.
The USB port supplies power as per USB 2.0 specifications. Use only USB 2.0-compliant USB
devices for the USB port. The port might not identity USB devices that are not compliant with USB
2.0.
NOTE:
USB devices from different vendors vary in compatibilities and drivers. H3C does not guarantee
correct operation of USB devices from other vendors on the switch. If a USB device fails to operate
on the switch, replace it with one from another vendor.
QSFP28 port
The switch provides 64 QSFP28 ports. A QSFP28 port with a split-capable 100-GE transceiver
module or cable installed can be split into four 25-GE breakout interfaces to improve port density. A
QSFP28 port with a split-capable 40-GE transceiver module or cable installed can be split into four
10-GE breakout interfaces to improve port density.
On the S9820-64H switch, only odd-numbered interfaces can be split. When an odd-numbered
interface is split, the interface with the number as the odd number + 1 is deleted.
You can install the following transceiver modules and cables in the QSFP28 ports:
•
QSFP28 transceiver modules in Table4-5.
•
QSFP28 copper cables in Table4-6.
•
QSFP28 fiber cables in Table4-7.
•
QSFP28 to SFP28 copper cables in Table4-8.
•
QSFP+ transceiver modules in Table4-9.
•

NOTE:
•
You can use a QSFP-40G-SR4-MM850 or QSFP-40G-CSR4-MM850 transceiver module to
connect a QSFP+ port to four SFP+ ports. The QSFP+ transceiver module and SFP+ transceiver
modules to be connected must be the same in specifications, including central wavelength and
fiber type.
•
MPO connectors include physical contact (PC) connectors with a flat-polished face and
angle-polished contact (APC) connectors with an angle-polished face (8°).
•
The QSFP-40G-LR4L-WDM1300 and QSFP-40G-ER4-WDM1300 transceiver modules are
supported only in E6553 and later.
• The QSFP-40G-BIDI-WDM850 transceiver module is supported only in R6607 and later.

LEDs
System status LED
The system status LED shows the operating status of the switch.
Table4-13 System status LED description
LED mark Status Description
SYS
Steady green The switch is operating correctly.
Flashing green The switch is performing power-on self test (POST).
Steady red The system has failed to pass POST or a fault has occurred.
Flashing blue (3 Hz)
Helps you to locate the switch.
To locate the switch in the rack, execute the locator blink
blink-time command. The LED then flashes blue at 3 Hz.
Off The switch is powered off or has failed to start up.
QSFP28 port LED
Table4-14 QSFP28 port LED description
LED status Description
Steady green A transceiver module or cable has been correctly installed in the port. The port
has a link and is operating at 100 Gbps.
Flashing green The port is sending or receiving data at 100 Gbps.
Steady yellow A transceiver module or cable has been correctly installed in the port. The port
has a link and is operating at 10 Gbps, 25 Gbps, or 40 Gbps.
Flashing yellow (3 Hz) The port is sending or receiving data at 10 Gbps, 25 Gbps, or 40 Gbps.
Off No transceiver module or cable has been installed in the port, or no link is
present on the port.
Management Ethernet port LEDs
The switch provides a LINK/ACT LED for each management Ethernet port to indicate their operating
status.
Table4-15 Management Ethernet port LED description
LED mark Status Description
LINK/ACT
Off No link is present on the port.
Steady green The port is operating at 1000 Mbps.
Flashing green The port is receiving or sending data at 1000 Mbps.
Steady yellow The port is operating at 100 Mbps.
Flashing yellow The port is receiving or sending data at 100 Mbps.

Fan tray alarm LEDs
The LSWM1BFANSC, LSWM1BFANSC-SN, LSWM1BFANSCB, and LSWM1BFANSCB-SN fan
trays each provide an alarm LED.
Table4-16 Description for the alarm LED
Status Description
On The fan tray is faulty.
Off The fan tray is operating correctly or no power is present.
5 Cooling system
CAUTION:
The chassis and power
supplies use separate air aisles. Make sure the two aisles are not blocked
when the switch is operating.
To dissipate heat timely and ensure system stability, the switch uses the front-rear air aisle cooling
system. Consider the site ventilation design when you plan the installation site for the switch.
