HIMs and MIMs
You can install HIMs to provide 10-Gbps service processing capability and install MIMs to provide
high-density narrowband aggregation. The HIMs and MIMs can offer a variety of interfaces, including
serial, Ethernet, POS, and E1.
The H3C SR6604 and SR6608 routers support the mix of HIMs and MIMs.
Lightning protector for a port
Port protective unit–single port, maximum discharge current (8/20μs waveform): 5 kA, output voltage
(10/700μs waveform): core-core < 40 V, core-ground < 600 V.
For how to install the port lightning protector, see "
Installing a lightning protector for a network port ."
If part of the network cable of a copper Ethernet port must be routed outdoors, connect a lightning
protector to the cable before you plug the cable into the port.
• Lightning protector for 10/100 Mbps copper Ethernet ports—Single port, residual pulse energy
(8/20μs test pulse) 2.5 KA, output voltage (8/20μs waveform): core-core ≤ 15 V, core-ground ≤
300 V.
• Lightning protector for 1000 Mbps copper Ethernet ports—Single port, residual pulse energy
(8/20μs test pulse) 3 KA, output voltage (8/20μs waveform): core-core ≤ 15 V, core-ground ≤
300 V.
Power strip with lightning protection
If part of the AC power line is routed outdoors, use a power strip with lightning protection to connect the
AC power cord of the router to the AC power line to protect the router from being damaged by lightning
strikes.
You can attach the power strip to the rack, workbench, or wall of equipment room.
The specifications for the power strip with lightning protection that can be installed on the router are as
follows:
Maximum discharge current: 6500 A, protection voltage: 500 VAC to 220 VAC.
For how to install the power lightning protector, see "
Connecting the AC power supply to a power strip
with lightning protection ."
Surge lightning protector
Generally, you need to connect a surge protector before connecting a signal cable to the router. This can
protect electronic devices against surge over-voltage resulting from lightning strokes and other
interferences, and minimize impact on the router.
The router supports the following types of surge protectors:
• Surge protector—Maximum discharge current 2.5KA/protection voltage 25V--SMB-75J/
SMB-75J-1W-10Mbps
