iAccess Controller

Rack access control manages and monitors access to individual server cabinets within a data centre or IT environment.

Typically, organisations use technologies such as smart cards, keypads or biometric authentication to identify authorised users. As a result, they can control exactly who has permission to access each cabinet.

Building or room-level access control protects the wider data centre. However, it does not necessarily prevent someone inside that secure area from accessing an individual server rack.

Rack-level access control adds another security layer. It restricts access to specific cabinets and, therefore, helps reduce the risk of unauthorised access, accidental interference and insider threats.

Data centre access control usually secures the building, room or technical area. In contrast, rack access control protects individual server cabinets.

This additional level of control allows organisations to assign access permissions according to individual racks. Consequently, it can provide particular value in colocation facilities, shared IT environments and locations where different teams manage different equipment.

Rack-level access control improves physical security, accountability and traceability.

For example, organisations can restrict users to specific cabinets rather than giving them unrestricted access to every rack within a secure room. In addition, electronic access records provide evidence of who accessed equipment and when.

These capabilities can support security policies, compliance requirements and incident investigations.

iAccess controls access to individual server cabinets using Wiegand-compatible authentication devices.

It can also support remote locking and unlocking while recording access events. As a result, organisations gain greater control over who can access critical equipment and can maintain a historical record of that activity.

Yes. iAccess uses SNMP to integrate with compatible DCIM, BMS and NMS platforms.

This integration allows organisations to bring rack security information into a wider infrastructure management system. For example, Sensorium DCIM can combine iAccess information with data from environmental monitoring, PDUs and other connected infrastructure.

iAccess supports Wiegand-compatible access control devices, including smart card readers and compatible biometric readers.

In addition, organisations can use an optional keypad for PIN-based authentication. Authorised personnel can also control access remotely through the built-in web interface or an integrated management platform.

Yes. iAccess records access activity, including authorised and unauthorised attempts.

When you integrate the controller with a central management platform, SNMP information creates a detailed historical audit trail. Therefore, security and operations teams can review who accessed individual cabinets and when access occurred.

iAccess records rack access activity, including successful and unsuccessful access attempts.

These time-stamped records help security teams investigate unusual activity and establish an accurate history of cabinet access. In addition, iAccess can pass information to compatible DCIM, BMS or NMS platforms, where organisations can retain and review it as part of their wider security records.

Yes. You can connect up to two optional temperature and humidity sensors directly to iAccess.

However, if you need more extensive environmental monitoring, the iSensor Controller supports additional temperature and humidity sensors together with particle, CO2 and volt-free contact monitoring.

Yes. Its compact 1U design makes iAccess suitable for central data centres as well as remote IT rooms and distributed infrastructure.

Furthermore, the built-in web server and SNMP connectivity allow authorised teams to monitor and manage the controller remotely.

The 1U iAccess Controller mounts directly into a standard server cabinet.

You then connect the controller to the cabinet door locks, Wiegand-compatible readers, network and any optional environmental sensors. ADS can also provide bespoke harnesses when a project uses different compatible reader or handle configurations.

iAccess can send SMTP email notifications and SNMP traps when configured events occur.

For example, alerts can report access activity, changes in contact status or environmental threshold breaches. Consequently, operations teams can identify potential security or environmental issues quickly.

Security cages provide an important physical barrier around a group of racks. However, once an authorised person enters the cage, they may have physical access to every cabinet inside it.

Rack-level access control adds another layer of protection by restricting users to specific cabinets according to their permissions. In addition, it records individual access events, which provides greater accountability and traceability.
