Materials
In general, a node is composed of Rack + Power Supply Unit + OCP servers + Switch. Please find below detailed explanations, feel free to check on the Rapid.Space Shop for purchase.
Rack
- 21' OCP Rack is the preferable option, if the hosting DC only provide 19' traditional rack, ESA Kit (supplied by Mitac) can be used to adapt the existing 19' rack to OCP servers.
- A power cable supply should be prepared with the rack:
- For one-phase power supply hosting site, the schema is Rack Input Cable Schema For Single Phase 20190712.
- For three-phase power supply hosting site, the schema is XX.
- Attention: on both schema, replace the Phoenix connector with reference 1967508 and adapt the component No.2 to the hosting site plug type.
Power Supply Unit
- There is one or several powershelf per rack. Usually for ESA kit there is only one powershelf.
- A powershelf is made of:
- 1 RMU
- up to 5 PSU (up to 6 PSU for a powershelf in OCP rack)
- One PSU is 3kW
- The number of PSU inside the powershelf is related to the quantity of ESA Kit and quantity of OCP servers installed in the ESA Kit. Usually, one 16OU ESA kit should use 2+1 PSU (6kW+3kW) for 19"EIA: 6kW for normal usage and 1 backup PSU in case one of the other 2 fails.
Switch
- In DC with existing traditional rack, a switch may already be equipped (double-check if it support the 10 Gbps between servers and has SFP+ ports).
- In DC without existing rack, a Switch should be purchased (from Edgecore, etc) to ensure the 10 Gbps between servers, it is recommended to purchase the Edgecore Switch AS5812.
- C13-C14 cables to power on the Switch (the powershelf has 2 C13 outlets directly powered from the input feed).
- SFP+ Cable ET5402-DAC-2M to connect Switch to each OCP servers.
OCP server
- Tiogapass OCP server (Mitac - New)
- Recycled OCP server (IT Renew - Recycled)
- Capri OCP Server (Mitac - New)
The number of servers are depending on which and how many rack will be installed. For example, a 21' Open Rack can filled with maximum 36 OCP servers, a 16OU ESA Kit rack can filled with maximum 16 OCP servers. In addition, please make sure the maximum kw available per rack is being strictly followed.
OCP server should meet at least the following standard concerning the configuration:

| SFP+ to RJ-45 transceiver |
If the internet connection in the hosting environment is a coper cable in RJ45 format, it is needed (reference: https://www.amazon.fr/Compatible-SFP-Ge-T-1000Base-T-Transceiver-connecteur/dp/B01AW5EHKG). If the internet connection in the hosting environment is a fiber cable directly in SFP format, then no need to prepare this tool. |

Remote Maintenance Device
Remote maintenance are required from time to time. The main tools that should be kept on-site to assist maintenance are:
- "Raspberry Pi"(with power supply +SD card)
- Ethernet cable
- Normal socket around to power on the RPi
