# Replacing an NVS Card

To replace an NVS card in slot 0 or slot 1 of an SRP module:

| Caution: Before you insert or remove an NVS card from a running SRP module, we strongly recommend that you halt the SRP module or shut down the router. Failure to do this can result in file corruption in one or both cards. See JunosE System Basics Configuration Guide, Chapter 6, Managing Modules for information about the halt command.

1. Obtain an antistatic container for the NVS card you plan to remove. (See Storing Modules and Components.)
2. Be sure you have halted the SRP module using the halt command. See Upgrading a System That Contains One SRP Module.
3. With a small flathead screwdriver, remove the faceplate from the NVS card slot on the SRP module.
4. Eject the NVS card. (See Figure 29.)
   - Slot 0—Insert a paperclip or similar device in the hole beneath slot 0 to eject the NVS card.
   - Slot 1—Use a screwdriver or similar device to depress the button beneath slot 1 and eject the card.

5. Remove the NVS card and place it in the antistatic container.
6. Insert the new NVS card into the slot and push it until it clicks into place.
7. Replace the faceplate on the NVS card slot.
