Class A 警语
Stromkabel. Dies muss von dem Land, in dem es benutzt wird geprüft
werden:
Schweiz Dieser Stromstecker muß die SEV/ASE 1011
Bestimmungen einhalten.
Europe Das Netzkabel muss mit IEC 60227 (IEC 60227

(”SCHUKO”).
Warning
:
This product does not contain any serviceable user
parts.
Warning
:
Installation and removal of the unit must be carried
out by qualified personnel only.
Warning
:
When connecting this device to a power outlet,
connect the field ground lead on the tri-pole power plug to a
valid earth ground line to prevent electrical hazards.
Warning
:
This switch uses lasers to transmit signals over fiber
optic cable. The lasers are compliant with the requirements of a
Class 1 Laser Product and are inherently eye safe in normal
operation. However, you should never look directly at a
transmit port when it is powered on.
Warning:
When selecting a fiber QSFP28 device, considering
safety, please make sure that it can function at a temperature
that is not less than the recommended maximum operational
temperature of the product. You must also use an approved
Laser Class 1 QSFP28 transceiver.
Caution
:
Wear an anti-static wrist strap or take other suitable
measures to prevent electrostatic discharge when handling this
equipment.
Caution
:
Do not plug a phone jack connector in the RJ-45 port.
This may damage this device.
Caution
:
Use only twisted-pair cables with RJ-45 connectors
that conform to FCC standards.
Caution:
The switch includes plug-in power supply (PSU)
and fan tray modules that are installed into its chassis. All
installed modules must have a matching airflow direction.
That is, if the installed power modules have a front-to-back
(F2B) airflow direction, all the installed fan tray modules
must also have a F2B airflow direction.
Caution:
Installing the switch into the rack-rails requires
two people. One person should hold the switch in position
close to the inner slide-rails, while the other slides the ends
of the slide-rail brackets into the rail assembly
.
警告:
此产品不含任何用户可维修的部件。
警告:
本机的安装和拆卸必须由专业人士来完成。
警告:
在将此设备连接到电源插座时,将三插片电源插头
上的接地导线连接到有效的接地线路,以防止电气危险。
警告:
此交换机使用激光器通过光纤线缆发射信号。这些
激光器符合 1 类激光产品的要求,在正常使用情况下对眼
睛无害。但是,切勿在电源开启状态下直接注视发射端口。
警告:
在选择光纤 QSFP28 设备时,为安全起见,请确保其
可以在不低于为产品建议的最大工作温度下工作。此外,还
必须使用经过认可的激光 1 类 QSFP28 收发器。
小心:
为防止静电释放,在操作此设备时,应戴上防静电
腕带或采取其他必要措施。
小心:
请勿将电话插头插入 RJ-45 端口。否则,可能损坏
此设备。
小心:
只应使用符合 FCC 标准且带有 RJ-45 接头的双绞线。
小心:
本交换机的机箱中安装有插入式电源 (PSU) 和风扇
架模块。所有后部安装模块都必须具有匹配的气流方
向。即,如果安装的电源模块有从前到后 (F2B) 的气流通
过,则所有安装的风扇架模块也必须有 F2B 气流通过。
小心:
在机架滑轨上安装交换机需要两个人。一个人应使
交换机靠近内侧滑轨就位,同时另一个人将滑轨支架端头滑
入滑轨装置。
警告:
此为 A 级产品,在生活环境中,该产品可能会造成
无线电干扰。在这种情况下,可能需要用户对其干扰采取切
实可行的措施。
