Removing and Replacing the Chassis Cover
These are the steps to remove the chassis cover:
1. Confirm the router is turned off and disconnected from the power supply or power supplies.
2. Place the chassis on a flat surface.
3. Remove the screws at top of the chassis cover.
4. Remove the screws at the sides of the device (See Figure 11).
5. Lift the chassis cover once you have removed all the screws.

To replace the chassis cover, place the cover evenly on the top of the device and use the screws to secure it
to the device.
Note
Replacing the Power Supply
These are the steps to replace the power supply:
1. Disconnect the power cord from the power supply.
2. Remove the bezel. The bezel is secured with snap latches. To remove the bezel, hold the top and bottom,
and pull the bezel.
3. The latch that secures the power supply to the device is on the right. Press the latch to the left and pull
out the power supply using the handle.
Figure 2: Power Supply Latch and Handle
4. Insert the replacement power supply.
5. Replace the bezel.
Installing Drive Bays
There are two drive bays. You can use one of them, both of them, or none. Refer to Hardware Features -
Replaceable and Upgradable Units to know the types of storage module that each of this bay can hold. If you
had not ordered drives, the slots are closed with a blank cover as shown in the image.
These are the steps to install a drive in a drive bay:
1. The drive bays are in the front panel of the device. The bays are closed with a cover if there are no drives
in the slots.

Upgrading the M.2 Storage Module
The M.2 storage module is a hardware that is 22mm wide and 80mm long. This hardware comes with different
storage capacities.
These are the steps to upgrade the M.2 memory module:
1. Remove the chassis cover.
2. Locate the M.2 storage module. Refer to the Chassis - Internal View section to identify and locate the
module.
3. Remove the old storage module by unscrewing the screw that secures the hardware and removing out the
storage module.
4. Plug in the new storage module in the same location and secure it with the screw.

Installing and Removing a DIMM
There are two DDR4 DIMM slots. DIMMs have a polarization notch on the connecting edge to prevent
incorrect insertion.
Figure 5: DIMM Showing Polarization Notch
These are the steps to install a DIMM:
1. Remove the chassis cover.
2. Locate the DIMM module on the device.

These are the steps to remove a DIMM:
1. Remove the chassis cover.
2. Locate the DIMM module on the device. Refer to the Chassis - Internal View section to identify and locate
the DIMM module.
3. Pull the latches away from the DIMM at both ends to lift the DIMM slightly. Pull the DIMM out of the
socket.

Installing and Removing a NIM
These are the steps to install a NIM:
• Locate the NIM slot on the front panel.
• Loosen the screws to open the slot cover.
• Insert the NIM into the slot.
• Tighten the screws to secure the NIM in the slot.
These are the steps to remove a NIM:
• If the NIM is up and running, issue the following command to shut down the NIM gracefully before
removing it:
hw-module subslot slot 0/2 stop
If you do not shut down the NIM gracefully before removing it, the NIM card
could get damaged.
Caution
• Locate the NIM slot on the front panel.
• Loosen the screws that secure the NIM.
• Gently pull out the NIM from the slot.
ENCS supports hot swap or OIR (Online Insertion and Removal) for NIM. So, you can insert and remove the
NIM when ENCS is running; however, before removing the NIM, ensure that the NIM is shut down gracefully.
