3 FRUs and compatibility matrixes
CAUTION:
•
Select fan trays and power supplies with airflow directions that meet the ventilation requiremen
ts
at the installation site. As a best practice, make sure the power supplies and fan trays have the
same airflow direction.
•
Do not install fan trays of different models on the same switch. To guarantee adequate heat
dissipation, install five fan trays of the same model on the switch.
•
Do not install power supplies of different models on the same switch. As a best practice, install
two power supplies of the same model on the switch for 1+1 power supply redundancy.

powering off the switch.
To avoid device damage and body injury, make sure the power supply
to be
replaced is powered off before you replace it.

IMPORTANT:
•
As a best practice, use H3C transceiver modules and cables for the switch.
•
The H3C transceiver modules and cables are subject to change over time. For the most
up-to-date list of H3C transceiver modules and cables, contact H3C Support or marketing staff.

USB port
The switch has one OHC-compliant USB2.0 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 file system of the switch,
for example, to upload or download application and configuration files.
IMPORTANT
:
•
USB devices from different vendors vary in compatibility and driver. H3C does not guarantee
correct operation of all USB devices on the switch.
If a USB device fails to operate on the switch,
replace it with one from another vendor.
•
The USB port on the switch is designed to output current in strict accordance with the USB 2.0
standard. For a USB storage device to be identified by the USB port, make sure the USB device
fully complies with USB 2.0.
SFP+ port
An S6805-54HF switch provides 48 SFP+ ports. The SFP+ ports support the following transceiver
modules and cables:
•
Gigabit SFP transceiver modules in Table4-5.
•
10-Gigabit SFP+ transceiver modules in Table4-6.
•
10-Gigabit SFP+ copper cables in Table4-7.
•
10-Gigabit SFP+ fiber cables in Table4-8.

4-13
IMPORTANT:
•
To use a Gigabit SFP transceiver module except for an SFP-GE-T or SFP-GE-T-D transceiver
module to connect an SFP+ port on the switch to the peer end, disable autonegotiation on the
peer end.
•
Installed with an SFP-GE-T or SFP-GE-T-D transceiver module, an SFP+
port can operate only
at 1 Gbps.

1/10GBASE-T autosensing Ethernet port
An S6805-54HT switch provides forty-eight 1/10GBASE-T autosensing Ethernet ports.
When a 10GBase-T Ethernet interface on an S6805-54HT switch operates at 1 Gbps, you must
configure the speed 1000 command on the local end.
If you execute the speed and duplex commands or their undo forms on a 10GBase-T Ethernet
interface on an S6805-54HT switch or its peer interface, the interface will go down and then come
up.

Transmission medium and max
transmission distance
•55 m (180.45 ft) over category-6 unshielded twisted pair cable
•100 m (328.08 ft) over category-6 shielded twisted pair cable
•100 m (328.08 ft) over category-6A or above twisted pair cable
Compatible standards •IEEE 802.3ab
•IEEE 802.3an
To avoid interference between cables, layer cables as follows:
•
Use category-6A or above cables and connectors.
•
Do not bundle cables in their first 20 m (65.62 ft).
•
Separate power cords and twisted pair cables at and around the distribution frame.
•
For ports adjacent to one another on the device, the peer ports on the distribution frame are
preferably not adjacent, for example:
If the device connects to one distribution frame, connect port 1 on the device to port 1 on the
distribution frame, port 2 on the device to port 3 on the distribution frame, and port 3 on the
device to port 5 on the distribution frame.
If the device connects to two distribution frames, connect port 1 on the device to port 1 on
distribution frame 1, port 2 on the device to port 1 on distribution frame 2, and port 3 on the
device to port 2 on distribution frame 1.
LEDs
System status LED
The system status LED shows the operating status of the switch.

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 POST, or a fault has occurred.
Flashing red Some ports have failed POST.
Flashing blue (3 Hz) Helps you to locate the device.
To locate the device, execute the locator blink command on
the device. Then the SYS LED will be in this state.
Off The switch is powered off or has failed to start up.
SFP+ port LED
Each SFP+ port has a status LED to show its operating status and activities.
