Removal and Replacement Procedures
Preventing ESD Damage
ESD damage might occur when modules or other FRUs are improperly handled, resulting in intermittent or complete failure of the modules or FRUs. Modules consist of printed circuit boards that are fixed in metal carriers. EMI shielding and connectors are integral components of a carrier. Although the metal carrier helps to protect the board from ESD, always use an ESD-grounding strap when handling modules. To prevent ESD damage, follow these guidelines:
-
Always use an ESD wrist or ankle strap and ensure that it makes good skin contact.
-
Connect the equipment end of the strap to an unfinished chassis surface.
-
When installing a component, use an available ejector lever or captive installation screws to properly seat the bus connectors in the backplane or midplane. These devices prevent accidental removal, provide proper grounding for the system, and help to ensure that bus connectors are properly seated.
-
When removing a component, use an available ejector lever or captive installation screws to release the bus connectors from the backplane or midplane.
-
Handle carriers by available handles or edges only; avoid touching the printed circuit boards or connectors.
-
Place a removed component board-side-up on an antistatic surface or in a static-shielding container. If you plan to return the component to the factory, immediately place it in a static-shielding container.
-
Avoid contact between the printed circuit boards and clothing. The wrist strap only protects components from ESD voltages on the body; ESD voltages on clothing can still cause damage.
-
Never attempt to remove the printed circuit board from the metal carrier.
Removing and Replacing a Supervisor Module
While Cisco Catalyst 9400 Series supervisor modules support hot swapping or Online Insertion and Removal (OIR), which lets you install, remove, replace, and rearrange supervisor modules without powering off the system, you must observe a wait time before removal or replacement.
 Note |
|
When the system detects that a supervisor module has been installed or removed, it runs diagnostic and discovery routines automatically, acknowledges the presence or absence of the module, and resumes the system operation with no operator intervention.
Warning |
Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030 |
Warning |
Ultimate disposal of this product should be handled according to all national laws and regulations. Statement 1040 |
Required Tools
You will need these tools to install or remove supervisor modules and line cards:
-
Your own ESD-prevention equipment or the disposable grounding wrist strap included with all upgrade kits, field-replaceable units (FRUs), and spares.
-
Antistatic mat or antistatic bag
-
Number 1 and number 2 Phillips screwdrivers for the captive installation screws on most modules
-
3/16-inch flat-blade screwdriver for the captive installation screws on some modules
Installing a Supervisor Module
Warning |
Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when servicing. Statement 1034 |
 Caution |
To prevent ESD damage, handle supervisor modules by the carrier edges only. |
Before you begin
-
Verify chassis compatibility and slot restrictions.
-
Verify that both the supervisor modules (in a redundant configuration) are of the same type.
-
You will need a Phillips screwdriver to tighten the captive installation screws.
Procedure
| Step 1 |
Take the necessary precautions to prevent ESD damage. Wear a grounded ESD wrist strap while handling the modules, and keep them in ESD-protective bags when they are not installed in a chassis. |
||||||
| Step 2 |
Ensure that you have enough clearance to accommodate any interface equipment that you will connect directly to the supervisor module ports. |
||||||
| Step 3 |
If a slot blank cover (C9400-S-BLANK=) is present, loosen the two captive installation screws that secure the cover and remove it. Save it for future use. |
||||||
| Step 4 |
Remove the new supervisor module from the shipping packaging, being careful to handle the module using only the module’s metal tray or the front panel. Do not touch the printed circuit board or the connector pins. |
||||||
| Step 5 |
Pivot the two module ejector levers out and away from the faceplate |
||||||
| Step 6 |
Grasp the supervisor module's front panel with one hand and place your other hand under the carrier to support the module. |

Removing a Supervisor Module
Warning |
Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when servicing. Statement 1034 |
Warning |
Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 1051 |
Caution |
To prevent ESD damage, handle supervisor modules by the carrier edges only. |
Before you begin
-
You will need a Slot Blank Cover (C9400-S-BLANK) if the slot is to remain empty.
-
You will need a Phillips screwdriver to loosen the captive installation screws.
Procedure
| Step 1 |
Take the necessary precautions to prevent ESD damage. Wear a grounded ESD wrist strap while handling the modules, and keep them in ESD-protective bags when they are not installed in a chassis. |
||||
| Step 2 |
Disconnect any network interface cables attached to the ports of the supervisor module that you intend to remove. |
||||
| Step 3 |
If the module is equipped with removable optical transceivers, immediately install dust plugs into the transceiver’s optical bores. This prevents possible dust contamination, which can affect port performance. |
||||
| Step 4 |
Loosen the two captive installation screws on either end of the supervisor module faceplate. |
||||
| Step 5 |
Grasp the left and right ejector levers at either end of the supervisor module faceplate and simultaneously pivot the levers outward to disengage the supervisor module from the backplane connector. 
|
||||
| Step 6 |
Grasp the front panel of the supervisor module with one hand and place your other hand under the carrier to support and guide it out of the slot. Do not touch the printed circuit boards or connector pins. |
||||
| Step 7 |
Carefully slide the supervisor module straight out of the slot, keeping your other hand under the carrier to guide it. |
||||
| Step 8 |
Place the supervisor module on an antistatic mat or in an antistatic bag. |
||||
| Step 9 |
Install a replacement supervisor module, or if the chassis slot is to remain empty, install a blank slot cover (C9400-S-BLANK).
Blanks should only be removed when installing a module and must be replaced if a module is ever removed.

Removing and Replacing an M.2 SATA SSD Module
The Serial Advanced Technology Attachment (SATA) is a computer bus interface that connects host bus adapters to mass storage devices such as hard disk drives, optical drives, and solid-state drives.
The supervisor module provides a SATA port that is connected to the CPU SATA port0. An M.2 connector is used to accommodate a 22 x 80 mm M.2 SATA SSD module on the supervisor board.
Prerequisites for Removal and Installation
-
If you are installing a new SATA module, we recommend that you install it - as is (raw SATA module, without partitioning). The system partitions the module as required.
-
If you are installing a previously used SATA module, before installing, ensure that the filesystem is ext2.
If the filesystem is the wrong format or is unrepairable, then the system creates a new ext2 filesystem; this will likely make any previously existing files unreadable and unrecoverable.
-
If you are creating partitions in a SATA module (new or used), we recommend that you use a Linux system to perform this task, ensuring that the first partition is a usable partition when connected to the switch.
-
Power down the system.
Note
The M.2 SATA SSD Module does not support hot-swapping; you must power down the system to install a new SSD module or to replace an SSM module on the supervisor board.
Warning |
Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030 |
Warning |
Ultimate disposal of this product should be handled according to all national laws and regulations. Statement 1040 |

Replacing a Battery
Warning |
Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030 |
Warning |
There is the danger of explosion if the battery is replaced incorrectly. Replace the battery only with the same or equivalent type recommended by the manufacturer. Dispose of used batteries according to the manufacturer’s instructions. Statement 1015 |
The Cisco Catalyst 9400 Series Supervisor Modules use a lithium battery. This is not a field replaceable unit. The following battery models are supported:
-
Panasonic, Model 1632
-
Renata, Model 700296 (CR1632)
-
Varta, Model 06632 101 501 (CR1632)
Module Interfaces
The supervisor module has the following interfaces or ports: USB ports, console ports, management port, and uplink ports.
Warning |
To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables. Statement 1021 |
USB Type A Host Port
The USB 2.0 and USB 3.0 Type A host port (disk0) is the only external storage interface for this switch. The port is connected to the route processor, which allows the Cisco IOS software to access the port. A flash memory device can plug into this connector. Cisco IOS software provides standard file system access to the flash device: read, write, erase, and copy. The software also provides the ability to format the flash device with a FAT file system (FAT32 and FAT16).
Observe these guidelines when using USB flash drives:
-
There must be at least one partition on the USB flash drive. If the drive has more than one partition, then only the first partition is visible in the system (Cisco IOS).
-
If you partition the flash drive, we recommend that you use a Linux system to perform this task. This ensures that the first partition is a usable partition when connected to the switch.
Using a Windows or MacBook machine utility to perform this task may result in two partitions on the drive by default (partition for system information + actual usable partition). When such a flash drive is connected to the switch, the system displays only the first system information partition, and not the actual usable partition.
Console Ports
The supervisor module provides two types of console ports on the supervisor module front panel:
-
USB Console Port—This is the USB mini Type B Console Port.
-
Console Port (RJ-45 connector)—This console port allows you to access the switch either locally (through a console terminal) or remotely (through a modem). The console is an EIA/TIA-232 asynchronous, serial connection with hardware flow control and an RJ-45 connector.
Only one of the consoles is active at a time. When a USB host (PC) is plugged into the USB console port the hardware automatically switches over to use the USB console. Only a PC which has the necessary USB console device driver causes the USB console to become active. Plugging in a PC that does not have the USB console driver support does not cause a switchover. When the USB cable is removed or the PC deactivates the USB connection, or a host is not detected on the USB console, the hardware automatically switches to the RJ45 console interface.
The default console port setting is 9600 baud, 8 data bits, no parity, 1 stop bit, and no flow control.
The console port allows you to perform the following functions:
-
Configure the switch from the CLI
-
Monitor network statistics and errors
-
Configure SNMP agent parameters
Ethernet Management Port
The supervisor module provides a standard 10/100/1000 BASET Ethernet management port. When managing a switch, connect the PC to the Ethernet management port of a Cisco Catalyst 9400 Series switch supervisor module.
The Ethernet management port can be used (in ROMMON mode only), to recover a switch software image that has been corrupted or destroyed due to a network catastrophe. You can use the ethernet management port for out of band (OOB) ethernet network connectivity. It can be used for SSH/Telnet access and image download through the OOB IP network.
The specific implementation of Ethernet management port depends on the redundancy model you are applying.
The switch cannot route packets from the Ethernet management port to a network port, and from the network port to the Ethernet port. To obtain these, the GigabitEthernet 0/0 interface is automatically placed in a separate routing domain (or VRF domain), called Mgmt-vrf. (Observe the vrf forwarding Mgmt-vrf in the running configuration when you boot.)
Uplink Ports
The supervisor module has uplink ports that can be used to provide additional port capacity for a fully configured switch or can reduce the need to use a chassis slot for a module. These ports use hot-swappable optical transceivers.
Some uplink ports use small form-factor pluggable (SFP) transceivers, or SFP+ transceivers, or SFP28 transceivers, and some use Quad Small Form-Factor Pluggable (QSFP), or QSFP28 transceivers.
For more detailed information about uplink port configuration, see the Configuring Interface Characteristics chapter of the Interface and Hardware Components Configuration Guide of the required release.
SFP and SFP+ Ports
-
SFP and SFP+: Numbered 1 to 8 on C9400-SUP-1, C9400-SUP-1XL, and C9400-SUP-1XL-Y.
These ports are divided into two groups where port numbers 1 through 4 form one port group and port numbers 5 through 8 form a second group.
-
SFP+ only: Numbered 1 to 4 on C9400X-SUP-2 and C9400X-SUP-2XL.
These ports can be configured with SFP transceivers for 1-GE operations or SFP+ transceivers for 10-GE operations. 1 and 10-GE uplink ports operate in full-duplex mode only. Both transceivers use LC-type connectors (optical) or RJ-45 (copper). The SFP transceivers have LC connectors to interface with multimode fiber (MMF) cable and single-mode fiber (SMF) cable and RJ-45 connectors for the copper interfaces.
Each SFP module has an internal serial EEPROM that is encoded with security information. This encoding provides a way for Cisco to identify and validate that the SFP module meets the requirements for the device.
SFP28 Ports
-
Numbered 1 and 5 on C9400-SUP-1XL-Y.
-
Numbered 1 to 4 on C9400X-SUP-2 and C9400X-SUP-2XL.
These ports use SFP28 transceivers to support 25-GE uplinks.
QSFP Ports
-
Numbered 9 and 10 on C9400-SUP-1, C9400-SUP-1XL, and C9400-SUP-1XL-Y.
-
Numbered 5 to 8 on C9400X-SUP-2 and C9400X-SUP-2XL.
These ports can be configured with QSFP transceivers for 40-GE operations. QSFP transceivers use LC, copper, or MPO-12 connectors.
Note |
Breakout cables are not supported. |
QSFP28 Ports
Numbered 5 to 8 on C9400X-SUP-2 and C9400X-SUP-2XL.
These ports can be configured with QSFP28 transceivers for 100-GE operations.
Uplink Port Configuration for C9400-SUP-1, C9400-SUP-1XL, and C9400-SUP-1XL-Y
Guidelines
These guidelines apply to a non-redundant (single supervisor) setup:
-
SFP or SFP+ port numbers 1 through 4 and QSFP port 9 form a mutually exclusive set; Only one of them can operate at any given time – either the SFP/SFP+ port group or the QSFP port.
-
SFP or SFP+ port numbers 5 through 8 and QSFP port 10 form a mutually exclusive set; Only one of them can operate at any given time – either the SFP/SFP+ port group or the QSFP port.
From the above, it follows that
-
To use all 8 SFP or SFP+ ports, all QSFP ports must be disabled.
-
To use both QSFP ports, all SFP or SFP+ ports must be disabled.
-
To use SFP or SFP+ ports 1 through 4, QSFP port 9 must be disabled, and vice versa.
-
To use SFP or SFP+ ports 5 through 8, QSFP port 10 must be disabled, and vice versa.
In addition to the above, this guideline applies to a redundant setup (dual supervisor) setup:
SFP or SFP+ port numbers 5 through 8 and QSFP port 10 of the active and standby supervisor modules are always inactive.
From the above, it follows that
-
If QSFP port 9 is active on supervisor module 1 and inactive on supervisor module 2, SFP or SFP+ ports 1 through 4 are inactive on supervisor module 1 and active on supervisor module 2.
-
If QSFP port 9 is active on supervisor module 2 and inactive on supervisor module 1, SFP or SFP+ ports 1 through 4 are inactive on supervisor module 2 and active on supervisor module 1.
-
If QSFP port 9 is active on supervisor modules 1 and 2, SFP or SFP+ ports 1 through 4 on both supervisor modules are inactive.
-
If QSFP port 9 is inactive on supervisor modules 1 and 2, SFP or SFP+ ports 1 through 4 on both supervisor modules are active.
