2.1 Rail Installation
The OWC Jupiter Kore comes with rack mount slide rails attached to the sides of the unit and the necessary screws and cage nuts for installing into 4-post square-hole rack systems. To install the slide rail brackets into your rack, do the following:
- The Jupiter Kore requires two (8-bay) or three (16-bay) rack units of space. Take note of which units in your rack that you will install your Jupiter Callisto into.
- Install the included cage nuts into your rack. Use as a guide for cage nut placement for an 8-bay Jupiter Kore; use for a 16-bay Kore.

-
On the OWC Jupiter Kore, remove the securing screw from the rail on the left and right sides as seen in Figure 2.1c.
-
Once the securing screws have been removed, remove the rail arm by sliding it toward the rear of the unit as seen in When the rail arm stops, push the release tab while continuing to slide the rail arm off. After removing the rails, set them aside taking note of the side from which they were removed.

Figure 2.1c

Figure 2.1d
- Remove the rail arm extensions from the accessories box and match them to the rails. Use as a guide for proper matching of rails and the extension pieces.

Figure 2.1e
- Install the front rails, first making sure the bottom of the rail lines up with the bottom of the designated rack units. Using Figure 2.1f as a guide for an 8-bay and for a 16-bay unit, secure the rail using two of the included M5 pan head screws.

- Before securing the rear rail extension to the back of your rack, make sure to slide the extension into the rail as seen in Figure 2.1h.

- After repeating the steps for the other side, you can now move on to installing the Jupiter storage system into the rack as found in Section 2.2, Unit Rack Installation and Removal below.
2.2 Rack Installation & Removal
After installing the rails, the Jupiter Kore can be installed into the rack. The Jupiter Kore is heavy even when no drives are installed. Never lift heavy equipment by yourself and always use proper lifting techniques. It is recommended that you remove all drives from the Jupiter Kore before installing into or removing from a rack in order to avoid personal injury or damage to equipment.
Rack Installation
-
Before lifting and installing the Jupiter Kore into the rack, make sure all people involved in lifting know where the unit rails are attached to the Jupiter Callisto and how they will slide into the rack rails.
-
Using proper lifting techniques and keeping the Jupiter Kore level, lift up to the rack rails where the unit will be installed into.
-
Visually align the unit rails with the rack rails.
-
Once aligned, evenly slide the unit rails into the rack rails. Do not release the unit until it has been inserted all the way or until an audible click is heard. The click indicates that the Jupiter Kore has been inserted past the security latches as illustrated in

Figure 2.2.1a
- If not already done, insert the Jupiter Kore all the way into the rack until the rack ears touch the rack posts.
- Install the four included rack securing screws to finish the unit installation into the rack as seen in The 16-bay version is shown, but the screw placement is similar on the 8-bay version.

Figure 2.2.1b
Rack Removal
-
Before removing the Jupiter Kore from your rack, it is recommended that you remove all drives to make it easier to remove the Jupiter Kore from the rack and to reduce the risk of personal injury and/or equipment damage.
-
Make sure all cables including data and power are disconnected from the Jupiter Kore.
- Remove the four rack securing screws from the front of the Jupiter Kore as shown in

-
Using the handles, pull the rack toward you until it is stopped by the security latches.
-
It is recommended to have a second person assist the removal at this point. Press the security latches while simultaneously sliding the unit out just past the security latch as illustrated in

Figure 2.2.2b
- Make sure both people removing the unit have a firm grip on the rack front and base and are prepared to support the full width of the unit. Continue slowly pulling the rack out until it is free from the rails.
2.3 Drive Installation & Removal
The OWC Jupiter Kore comes with drives already installed into the individual trays to provide quicker setup time. Use the following instructions to install and remove drives from the drive bays.
Drive Installation
- Begin by placing the OWC Jupiter Kore on a static free work surface. Careful remove the drive trays from the packaging.
- Each drive tray is labeled with a number. Additionally the drive trays have locking mechanisms. Press down on the locking mechanism to lock the drive tray. A small amount of red will show indicating the drive tray is locked. Press up to unlock the drive tray. The small amount of red will no longer appear indicating the drive tray is unlocked.

5.1 Troubleshooting
• Networking Issues
- Make sure Drivers are installed if needed for Client machines. This would be apparent if an Adapter or NIC card didn't show on the Client machine for configuration.
- Check Patch Cables, swap out cable with known good one.
- Double check IP address on Server/Client. Make sure they are on the same IP range and Subnet. (Static IP: 192.168.0.010/ 255.255.255.0, DHCP IP: 172.27.x.x/ 255.255.255.0)
- Swap out Adapters on Client machine (MacBookPro / MacBookAir / Windows PC)
- Plug in monitor to check if the OS is reporting an issue via Shell.
• Double check Jumbo Frames on Server/Client. - Check Link speed of hardware on Client NIC. May need to Manually set 10G speeds or higher depending on the NIC in question.
• Share Issues
- Double check all IP addresses involved with testing the Share. Check Both the Server and Client.
- Check Permissions on the dataset.
- Check Share path to make sure it is set appropriately.
