Hardware Installation Guide for Cisco 8300 Series Secure Routers
Outlines how to remove and install an M.2 USB|NVMe module, including electrostatic discharge prevention and task-specific steps for safe module removal and installation.
This section describes installing and replacing an M.2 USB|NVMe module on the Cisco 8300 Series Secure Routers.
The M.2 module is sensitive to electrostatic discharge (ESD) damage, which can occur when electronic cards or components are handled improperly. ESD results in complete or intermittent failures.
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.
Place the M.2 storage devices on an anti-static surface or in a static shielding bag. If you have to return the device to the factory, immediately place it in a static shielding bag.
Avoid contact between the device and clothing. The wrist strap protects the device from ESD voltages on the body only; ESD voltages on clothing can still cause damage.
Do not remove the wrist strap until the installation is complete.
For safety, periodically check the resistance value of the anti static strap. The measurement should be between 1 and 10 megohms (Mohms).
To remove a M.2 USB|NVMe module, perform these steps:
The M.2 USB|NVMe module installation for C875-E-G2. The M.2 USB|NVMe modules are flipped upside down.
| 1. | The device should be powered down and the power supply disconnected before you perform any module replacement. |
|||
| 2. | Loosen 2 mounting screws using a #1 Philips screwdriver. |
|||
| 3. | Gently pull the M.2 USB|NVMe module out and remove it from the device. 
|
To install the M.2 USB|NVMe module, perform these steps:
For the C8375-E-G2, the PCB faces down.
| 1. | Read all Safety Warnings, ensure that the C8375-E-G2 is not powered on. |
|||
| 2. | Insert the M.2 USB|NVMe module into the slot of the device (as shown in the figure). The slide should engage the internal card guides. |
|||
| 3. | Gently slide the M.2 USB|NVMe module all the way in until the faceplate is flush with the device. |
|||
| 4. | Screw down and tighten the two Philips head screws. Torque it to 4-6 in lbs. |
|||
| 5. | The device can now be powered on.
