Determining Installation Positions
Before installing controller enclosures and disk enclosures, determine their installation positions in a cabinet. This greatly improves installation efficiency.
Prerequisites
The following installation tools and materials are ready:
- 2 U installation template (available in the accessory box)
- 4 U installation template (available in the accessory box)
- Marker
Context
- To facilitate the operation and maintenance of a controller enclosure, you are advised to install a controller enclosure between the 19th U and the 20th U in a cabinet. This section uses the recommended installation positions in a 42 U cabinet as an example. You can plan device positions based on site requirements.
- Below the controller enclosure, reserve a 2 U space for installing a cable tray and facilitating removing and inserting interface modules.
- You are advised to keep a 1 U (44.45 mm) space between storage devices. If the space is limited, it is recommended that five disk enclosures form a group, and at least a 1 U space be reserved between groups within the same cabinet to facilitate management and mitigate vibration transfer.
- You are advised to reserve a 2 U space at the bottom of the cabinet to facilitate cabling, ventilation, heat dissipation, and maintenance of the devices located in the lower part of the cabinet.
You are advised to install disk enclosures from the bottom up in descending order of weight.
Procedure
- Check the installation positions of the controller enclosure and disk enclosures in a cabinet, as shown in Figure 5-41.
Each three square holes correspond to 1 U height. Each 1 U height is lined out with a scale mark. If no 1 U scale mark is lined out on the front and rear columns of the cabinet, line out scale marks to facilitate locating installation positions.
- Align the bottom of the installation template with the integer U mark on the mounting bar of the cabinet, as shown in Figure 5-42 and Figure 5-43.
- Following the instructions on the installation template, insert the mounting ear of the installation template into the mounting bar to fasten the installation template.
The installation template can be regarded as the front panel of the device. The four indentations of the installation template are the positions of the screw holes that are used to secure a device.
- Use a marker to mark the positions of the screw holes where a device will be fastened on the mounting bar. Then, the installation positions of the controller enclosure and the disk enclosures are located.
