Mounting 3U SteelHead xx50 appliances in a rack
The SteelHead xx50 appliances ship with rails preinstalled to the appliance for mounting to a four-post rack. This section describes how to install the appliance in a four-post rack.
Before you begin the installation process:
• Unplug the AC power cords.
• Remove all external devices and connectors.
If your rack has square holes, use the included square post-hole adapters. For details, see “Square post-hole adapters” on page 9.
All 3U appliances must be mounted to a four-post rack; they can’t be mounted to a two-post rack.
3U appliances weigh from 59 to 71 lb (27 to 33 kg). At least two people are required to move a 3U appliance. Lift the appliance using both hands and with your knees bent.
The outer rails aren’t required to install the appliance in a shelving unit. Remove the outer rails before attempting to install the SteelHead xx50 in a shelving unit.
To detach the outer rails from the inner rails
• To detach the outer rails, slide the outer rail to the end of the appliance, pull the outer rail release tab toward the front of the appliance and pull the outer rail completely away from the appliance.
Figure 7‑16. Releasing the outer rail
To adjust the length of the outer rails
1. To adjust the length of the outer rails to fit the distance between your rack posts, loosen the screws on the longer rear bracket of the outer rails. You can tighten and secure the bracket screws after you have affixed the outer rails to the rack posts.
In some environments, you can’t reach the bracket screws after the rails have been installed. In this case the length of the outer rails should be adjusted and secured before mounting the outer rails into the rack.
Figure 7‑17. Adjusting the length of the outer rails
The screws on the front bracket are preadjusted, do not loosen those screws.
To install the outer rails to a rack
After you have detached the outer rails from the inner rails on the appliance and adjusted the length of the outer rails to fit your rack posts, you are ready to install the outer rail assemblies to the rack.
• Install the outer rails to the rack posts with the included screw set.
Figure 7‑18. Attaching the outer rails to the rack
The sliding part of the outer rails should not be extended when inserting or removing the appliance.
To mount the appliance in a rack
1. With two people lifting the appliance, gently slide the inner rails into the outer rails until you get to a hard stop.
The inner and outer rails must meet precisely, and the appliance must be held level to join the rails. The sliding part of the outer rails should not be extended when joining the inner and outer rails.
2. When the appliance has reached a hard stop, pull the release tabs on both of the inner rails and push the appliance all the way into the rack.
Figure 7‑19. Sliding the appliance into the rack and pulling the inner rail release tab
To operate the rails
• To pull out the appliance from the rack without removing it, pull it until it stops.
• To push the appliance back into the rack, use the inner rail release tab.
• To remove the appliance from the rack, pull until the outer rail release tab shown in Figure: Releasing the outer rail is visible.
Use caution when the appliance is mounted in a rack and the outer rails are extended. Do not place objects or additional weight on the appliance.
