• Rack Advanced

What do I have to bring when I install my servers?

The rack is completely empty, so you have to bring everything you need in the rack. This includes power strips / PDUs, cables and screws.

We provide the power supply via protective contact sockets (CEE 7/3 type F).

For the uplink, we usually provide a 1G RJ45 module, unless you have decided to use another uplink.

Can I send hardware to Hetzner Online?

Yes, you can send hardware to us.

After we have received your hardware, we can store it for you for a short time, or we can install it for you.

Please open a support request via your Robot account BEFORE sending us your hardware. In the support request, you will also find our postal address.

Can Hetzner Online install my hardware?

Yes, we can offer to install / exchange hardware or do general work on your hardware in the rack.

For this, we will charge you for a Remote Hands fee. We charge the Remote Hands fee based on 15-minute periods. If you go over 15 minutes, we will charge you an additional Remote Hands fee. So, for example, if it takes us 20 minutes to do the work, we will charge you for 2 fifteen-minute increments = two Remote Hands. You can find the current price for Remote Hands here.

If you want us to ship you any hardware that you have removed or switched out, please send us suitable packaging material and a prepaid package label.

How is the rack connected to the network?

The default connection to our racks is 1 GBit/s RJ45.

If you need a different connection, you will find additional options here.

You can also open a support request on Robot or, if you are not yet a customer, use our contact form.

How do you invoice the traffic?

We calculate monthly traffic consumption only from outgoing traffic. We do not charge you for incoming and internal traffic.

If you go over the traffic limit for your rack, we will charge you for each 1 TB that you go over.

How do you invoice the electricity?

We charge for electricity in monthly periods, and our price is per kWh of power that your rack consumes. You can find the current electricity price here: Colocation offers

What are the considerations for colocation rack power usage in terms of redundancy and maximum power capacity?

Depending on the model, your colocation rack is equipped with two or four power circuits. For racks with four circuits, the distribution is as follows:

1. A1 Feed
2. A2 Feed
3. B1 Feed
4. B2 Feed

Each circuit is protected by a 16 A circuit breaker, but the maximum allowable load per circuit is 10 A. You can use the circuits either redundantly to increase operational security or non-redundantly to utilize the maximum power capacity.

1. Redundant Usage (Recommended for Maximum Fail-Safety)

Racks with 2 Circuits

With redundant usage, you distribute the power load evenly across the A and B feeds, ensuring that each connected device continues operating even if one feed fails.

• Advantage: High availability. If the B feed fails, the A feed takes over the entire load.
• Disadvantage: The maximum usable power is 10 A per rack.

Example:

• 5 servers with 2 A each are connected to both the A and B feeds (dual power supply).
• If one feed fails, the remaining feed takes over the entire 10 A load.

Racks with 4 Circuits

The power load is evenly distributed across the A1/A2 and B1/B2 feeds.

• Advantage: Higher fail-safety.
• Option: Maximum redundant power capacity of 20 A, as the load can be distributed across two circuits.
• Disadvantage: Requires precise load balancing.

Example:

• 10 servers with 2 A each are connected to A1, A2, B1, and B2 (5 A per circuit).
• If one or more circuits fail, the remaining circuits can handle the load, provided the total load does not exceed 20 A.

2. Non-Redundant Usage (Maximum Power Capacity of 20 A or 40 A)

Racks with 2 Circuits

With non-redundant usage, you use the A and B feeds independently to achieve a maximum power capacity of 20 A.

Example:

• 5 servers (2 A x 5 = 10 A) are connected to the A feed.
• Another 5 servers (2 A x 5 = 10 A) are connected to the B feed.

If the B feed fails, only devices on the A feed remain operational.

Racks with 4 Circuits

The load is distributed independently across the A1, A2, B1, and B2 feeds to achieve a maximum power capacity of 40 A.

Example:

• 5 servers (2 A x 5 = 10 A) are connected to A1.
• 5 servers (2 A x 5 = 10 A) are connected to A2.
• 5 servers (2 A x 5 = 10 A) are connected to B1.
• 5 servers (2 A x 5 = 10 A) are connected to B2.

If one circuit fails, only devices on the remaining circuits remain operational.

Important Notes

• For redundant usage in racks with four circuits, it is possible to achieve a redundant power capacity of up to 20 A by distributing the load across all four circuits.
• For non-redundant usage, ensure that a circuit failure does not critically impact your environment.
• In all cases, the maximum load of 10 A per circuit must not be exceeded.

Is there equipment that I can use in the DC so I can set up my rack?

The following equipment is available in the DC:

• Service cart with monitor, keyboard and mouse
• Ladders
• Basic tools
• Workbench

Note: We urge you to bring your own tools. That way, things will go more smoothly for you when you set up your rack in the DC. We only provide a limited amount of basic tools.

Is WLAN available in the DC?

Yes, WLAN is available in the DC. You should only use the WLAN for your maintenance work. Please do not use it for personal use.

Warning: Do not use the WLAN as a backup uplink for your rack.

With Rack Basic, can I choose if I would like a key or code lock?

If you order Rack Basic, and you have a preference for what kind of lock you'd like, please write a quick comment in the comment field at the end of the ordering process.

Otherwise, we will assign you a rack based on availability. So it might have a key lock or a code lock.

(We cannot guarantee that we will have racks available with the kind of lock you prefer.)

How many transponders and keys can I get?

You can get up to two transponders per account and up to two keys per rack for free.

If you need more transponders or keys, please open a support request on Robot.
