• Panduit crimping tool with optional controlled-cycle mechanism (model CT-720, CT-920, CT-920CH,
• Wire-stripping tools.
• 12-gauge copper ground wire (insulated or not) for the single-hole ground connection.

Installing Network Modules

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
Modules, on page
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.
Before you begin
When installing network modules, observe these precautions:
• Do not remove the blank module from the slot unless you are installing an SFP or SFP+ module. Either
