Grounding the switch
连接保护地线
Correctly connecting the switch grounding cable is crucial to lightning protection and EMI
protection
.
交换机地线的正确连接是交换机防雷、防干扰的重要保障，请使用设备随机提
供的保护地线正确接地。
To use the grounding point on the rear panel of the chassis, install the grounding cable
by strictly following the figure below; otherwise, the installation and removal of power
supplies can be affected.
选用机箱后面板接地点接地时，请注意按照下面图示角度安装
地线，避免阻碍电源模块的安装和拆卸。
Method 1
—
Use the ground point on
the rear panel
交换机后面板接地
Method 2
—
Use the ground point on
the side panel
交换机侧面板接地

Installing a fan tray
安装可插拔风扇
Only the S5500-28SC-HI and S5500-52SC-HI support hot swappable fan trays.
LSPM1FAN blows air from the power side to port side, and LSPM1FANB draws air from
the port side to power side. Select a fan tray as needed.
仅
S5500-28SC-HI

52SC-HI
采用可插拔风扇，请您根据安装环境的需要选购合适的风扇：
LSPM1FAN
为吹风
风扇，风向为电源侧进风，端口侧出风；
LSPM1FANB
为抽风风扇，风向为端口侧进风，

安装电源模块
Method 1 - PSR150-A/PSR150-D/PSR150-A1/PSR150-D1
Method 2 - PSR360-56A/PSR720-56A/PSR1110-56A

Remove a power module: Press the latch inwards, and
pull the power module until it is part-way out. Hold the
handle to pull the power module slowly out of the slot.
拆卸电源模块：向拉手侧掰动锁闩，同时向外轻微用力
拉出部分电源模块，然后握住拉手拉出整个电源模块。
A PSR1110-56A adds 64 mm (2.52 in) to
the chassis depth, which includes the depth
of the power module handle.
如右图所示，
设备安装PSR1110-56A电源模块后，整机深
度会增加64mm（包含电源模块拉手深度）。
The switch provides one filler panel (filler module) for the power module slot. To prevent
dust and ensure good ventilation, promptly install a filler panel (filler module) for an
empty power module slot .
设备随机提供一个电源模块插槽假面板，若电源模块插槽
无须安装电源模块，为防止灰尘进入及保证交换机的正常通风，请及时安装假面板。
Remove a filler panel: Insert a flathead
screwdriver through the handle and pull the filler
module outward.
拆卸假面板：将一字螺丝刀插入
拉手，向外轻微用力拉出假面板
