This section describes how to replace the micro SD card and the precautions.

Precautions

If the micro SD card has one of the following conditions, replace the micro SD card:

The micro SD card is damaged. That is, the USG generates the micro SD card damage alarm: ENTEXT_1.3.6.1.4.1.2011.5.25.31.2.0.16 hwEntityExtDiskDamaged.
The micro SD card is full. That is, the USG generates the micro SD card full alarm: ENTEXT_1.3.6.1.4.1.2011.5.25.31.2.0.17 hwEntityExtDiskFull.

Read the precautions on using the micro SD card:

Micro SD cards are optional and are not delivered with the device. If required, purchase the micro SD card (part number: 06010308) from Huawei. The micro SD card model is SDSDQAE-064G, the capacity is 64 GB, and dimensions (H x W x D) are 1 mm x 15 mm x 11 mm (0.04 in. x 0.59 in. x 0.43 in.).
Make sure that you have worn an ESD wrist strap and the strap is well grounded before you hold the micro SD card. Otherwise, the micro SD card may be damaged.

The micro SD card can be replaced no matter when the USG is powered on or off. If the USG is powered off, skip the sd-card offline command. The following procedure guides you through micro SD card replacement while the USG is powered on.

Tools

Phillips screwdriver
ESD wrist strap

Procedure

Ensure that all configurations are saved.
In the system view, run the sd-card offline command. When the system displays a message indicating that the SD card is offline, remove the micro SD card to be replaced.
- Before replacing a micro SD card, run the sd-card offline command to prevent micro SD card damage and data loss.
- Do not use too much force; otherwise the micro SD or micro SD card slot might be damaged.
1. Loosen the screws on the anti-theft board and remove the anti-theft board.
2. Press the micro SD card along the guide rail to loosen the internal card clip. Then the micro SD card is ejected from the slot. You can then remove the micro SD card.
3. Place the replaced micro SD card properly.

1. Insert the micro SD along the guide rail to the micro SD card slot.
2. When you hear a click, the micro SD card is in position.
3. Hook the locating hook on the anti-theft board to the locating hole of the rear panel and tighten the captive screw on the anti-theft board.

In any view, run the display sd-card information command to check the micro SD card installation and file system mounting status. In the command output, SD Card Physical State should be Present, and SD Card File System State should be Mounted.
- If SD Card Physical State is Absent, re-install the micro SD card and try again. If SD Card Physical State remains the same, the USG may fail to identify the micro SD card. You are advised to use another micro SD card.
- If SD Card File System State is Unmounted, the micro SD card format might not be ext4. You need to run the reset sd-card command in the system view to format the micro SD card.

Follow-up Procedure

After replacing the micro SD card, collect all tools. If the replaced micro SD card is faulty, fill in the Repair Transmission Sheet and send the faulty module with the Repair Transmission Sheet to the equipment supplier or the specified repair service provider.
