Chapter 3 Installing a Network Module

Installing a Network Module in the Switch

Warning 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

Tools and Equipment

You need to supply a number-2 Phillips screwdriver.

Installing Network Modules

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

Note 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.

Note 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 “SFP and SFP+ Modules” section on page 1-8.

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

Note 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.

Step 1 Attach an ESD-preventive wrist strap to your wrist and to an earth ground surface.

Step 2 Remove the module from the protective packaging.
