Cisco Systems C3850NM210G Manual De Usuario

Do not reach into a vacant slot or chassis while you install or remove a module. Exposed circuitry 
could constitute an energy hazard. Statement 206

You need to supply a number-2 Phillips screwdriver.

Although network modules are hot-swappable, we recommend installing a network module before 
powering the switch. 

The switch can operate without a network module, but a blank module (with no ports or SFP slots) is 
available and should be installed when uplink ports are not required. 

The switch generates logs when you insert or remove a network module with SFP slots. 

Use only supported network modules and SFP or SFP+ modules. Each module has an internal serial 
EEPROM that is encoded with security information. For information about supported SFP modules, see 
the 

.

The network module is hot-swappable. If you remove a module, replace it with another network module 
or a blank module.

The switch complies with EMC, safety, and thermal specifications when a network module is present. 
If no uplink ports are required, install a blank network module. 

When installing network modules, observe these precautions:

Do not remove the EMC plug from the 10-Gigabit Ethernet slot until you install an SFP or SFP+ 
module. Either a module or a dust plug must be in the slot at all times.

Do not remove the dust plugs from the fiber-optic SFP modules or the rubber caps from the 
fiber-optic cable until you connect the cable. The plugs and caps protect the module ports and cables 
from contamination and ambient light.

Removing and installing a network module can shorten its useful life. Do not remove and insert a 
network module more often than is necessary.

To prevent ESD damage, follow your normal board and component handling procedures when 
connecting cables to the switch and other devices.

Attach an ESD-preventive wrist strap to your wrist and to an earth ground surface.

Remove the module from the protective packaging.
