Network Module Overview

Table 1 Network Modules 

Network Module 1	Description
C3KX-NM-1G (Figure 1)	The module has four 1-Gigabit SFP module slots. Any combination of standard SFP modules is supported. SFP+ modules are not supported. If you insert an SFP+ module in the 1-Gigabit network module, the SFP+ module does not work, and the switch logs an error message.
C3KX-NM-10G (Figure 2)	The module has four slots. Two slots support only 1-Gigabit SFP modules. Two slots support either 1-Gigabit SFP or 10-Gigabit SFP+ modules. Note The GLC-T SFP is not supported on the SFP+ slots of C3KX-NM-10G. The four slots are grouped as two pairs, with each pair consisting of one SFP slot and one SFP+ slot. Each pair supports either two 1-Gigabit SFP modules or one 10-Gigabit SFP+ module. A 10-Gigabit SFP+ module cannot operate at the same time as the corresponding 1-Gigabit SFP module in the pair. Supported combinations of SFP and SFP+ modules: •Slots 1, 2, 3, and 4 with 1-Gigabit SFP modules •Slots 1 and 2 with 1-Gigabit SFP modules and Slot 4 with one 10-Gigabit SFP+ module •Slot 2 with one 10-Gigabit SFP+ module and Slots 3 and 4 with 1-Gigabit SFP modules •Slot 2 and Slot 4 each with 10-Gigabit SFP+ modules A 10-Gigabit SFP+ module takes precedence over a 1-Gigabit SFP module except when an SFP module is first inserted in Slot 1 and has link. When you insert an SFP+ module in Slot 2, the SFP in Slot 1 retains link. The SFP+ module in Slot 2 does not operate. When the SFP module in Slot 1 is shutdown, loses link, or is removed, the SFP+ module in Slot 2 turns on. The SFP module in Slot 1 does not work as long as an SFP+ module is in Slot 2, whether it has link up or not. The same precedence applies to Slots 3 and 4.
C3KX-NM-10GT (Figure 3)	This module has two (copper) ports that support speeds of 1Gps or 10Gps. To change the speed, see the hw-module switch command in the Catalyst 3750-X and 3560-X Switch Command Reference.
C3KX-SM-10G (Figure 4)	This module has two slots that support either 1-Gigabit SFP or 10-Gigabit SFP+ modules. The service module supports Net Flow and MACSec Uplink Encryption (switch- to-switch encryption between uplinks). To configure the service module, refer to the Catalyst 3750-X and 3560-X Switch Software Configuration Guide.
C3KX-NM_BLNK (Figure 5)	The module has no ports.

Safety Warnings

This section includes the installation cautions and warnings. Translations of the safety warnings appear in the Regulatory Compliance and Safety Information for the Catalyst 3750-X and 3560-X Switches on Cisco.com:

http://www.cisco.com/go/cat3750x_hw

Read this section before you install a network module.

---

Caution Proper ESD protection is required whenever you handle equipment. Installation and maintenance personnel should be properly grounded by grounding straps to eliminate the risk of ESD damage to the equipment. Equipment is subject to ESD damage whenever you remove it.

---

Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030

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.

The network module is hot-swappable. If you remove a module, replace it with another network 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 a bare metal surface.

Step 2 Remove the module from the protective packaging.

Step 3 Remove the 10-Gigabit Ethernet module slot EMC plug, and save it.

---

Caution Verify the correct orientation of your module before installing it. Incorrect installation can damage the module.

---

---

Caution Do not install the network module with connected cables or installed SFP modules. Always remove any cables and modules before you install the network module.

---

---

Caution A module interface might become error-disabled when a network module with connected fiber-optic cables is installed or removed. If an interface is error disabled, you can re-enable the interface by using the shutdown and no shutdown interface configuration commands.

---

Step 4 Position the module face up to install it in the module slot. Slide the module into the slot until the back of the module faceplate is flush with the switch faceplate. Fasten the captive screws to secure the network module in place.

Figure 7 Installing the Network Module in the Switch

---

Removing a Network Module

---

Note The switch meets the applicable compliance and thermal specifications when a network module is present. If no uplink ports are required, install a blank network module.

---

---

Step 1 Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface.

---

Caution Do not remove the network module with installed SFP cables or modules. Always remove any cables and modules before removing the network module from the slot.

---

---

Caution A module interface might become error disabled when a network module with connected fiber-optic cables is installed or removed. If an interface is error-disabled, you can re-enable the interface by using the shutdown and no shutdown interface configuration commands.

---

Step 2 Disconnect the cables from the SFP modules.

Step 3 Remove the SFP modules from the network module.

Step 4 Loosen the captive screws that hold the network module in place.

Step 5 Carefully press the tab on the right side of the network module to release it. Grasp the edges of the module, and carefully slide it out of the slot.

Step 6 Install a replacement network module or a blank module in the slot.

Step 7 Place the module that you removed in an antistatic bag or other protective environment.

Installing SFP and SFP+ Modules

You must have an installed network module to use SFP and SFP+ modules.

See Table 3, Table 4, and the switch release notes on Cisco.com for the list of supported SFP and SFP+ modules. Use only supported SFP modules on the switch.

For cable specifications, see Appendix B in the switch hardware installation guide.

Observe these precautions:

Warning Class 1 laser product. Statement 1008

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

•Removing and installing an SFP module can shorten its useful life. Do not remove and insert any SFP 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.

---

Caution To avoid damage to the network module, install the network module before you install the SFP or SFP+ modules.

---

---

Step 1 Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface.

Step 2 Find the send (TX) and receive (RX) markings that identify the top of the SFP module.

On some SFP modules, the send and receive (TX and RX) markings might be shown by arrows that show the direction of the connection.

Step 3 If the SFP module has a bale-clasp latch, move it to the open, unlocked position.

Step 4 Align the module in front of the slot opening, and push until you feel the connector snap into place.

Figure 10 Installing an SFP Module in the Network Module

Step 5 If the module has a bale-clasp latch, close it to lock the SFP module in place.

Step 6 Remove the SFP dust plugs and save.

Step 7 Connect the SFP cables.
