Sophos XGS 4500 Redundant Power Supply

Sophos XGS 4500 Redundant Power Supply adds a second internal power module to the Sophos XGS 4500. It supports redundant firewall power for companies seeking less dependence on a single power supply. It is intended for this specific appliance model.

Reduce a potential point of failure

The XGS 4500 has a bay for the additional module. Two correctly connected, functioning modules enable redundant power. Benefits also depend on infrastructure: two cables connected to the same unprotected source do not protect against that source failing. Suitable feeds and, where appropriate, an uninterruptible power supply belong in the plan.

Prepare the upgrade correctly

According to Sophos installation instructions, the second module can be inserted while the existing primary supply powers the appliance. This differs from removing or replacing an installed module. Follow the appropriate manufacturer instructions for those tasks. After installation, check the connection and status of both modules.

Choose the right firewall accessory

This internal supply is exclusively intended for the XGS 4500. It differs from external redundant supplies for other XGS models. Confirm the precise model, existing equipment and planned power connections before ordering.

An additional supply improves power resilience within an appliance. Complete device failure or loss of the entire network connection requires further measures in the availability plan.
