IBM - 1747-HC1 - IBM System Storage EXP2512 single ESM

IBM 1747-HC1 – System Storage EXP2512 Single ESM

The IBM 1747-HC1 is a single ESM (Environmental Service Module) for IBM System Storage EXP2512 expansion enclosures, used to maintain stable drive-shelf connectivity and enclosure services in enterprise storage environments. It is a practical replacement part when restoring an EXP2512 shelf to full operational status or keeping spares for maintenance windows.

In mixed IBM storage estates, this ESM is typically deployed alongside related infrastructure components such as CONTROLLER options and host-side connectivity. Depending on your architecture, it may also be used in environments where RAID CONTROLLER components handle volume management and data protection upstream.

Key Features

Key technical characteristics of the 1747-HC1 ESM for professional storage maintenance and lifecycle support:

• Single ESM module design to replace a failed or missing ESM in an IBM System Storage EXP2512 enclosure.
• Compatibility with IBM System Storage EXP2512 drive expansion shelves to support ongoing operation of attached disk enclosures.
• Enclosure services integration to help maintain stable shelf monitoring and service functions within the EXP2512 platform.
• Hot-serviceable field replacement concept (platform-typical) to reduce downtime during planned maintenance in data center racks.
• Designed for enterprise storage duty cycles to support 24/7 operation in production and backup environments.
• Suitable for spare-part stocking to support break/fix maintenance workflows for IBM System Storage expansion infrastructure.
• Works within EXP2512 shelf architectures used across IBM storage deployments to help extend the lifecycle of existing installations.

Refurbished Quality and Warranty

This unit is refurbished hardware, cleaned and tested by technicians before entering stock to help reduce the risk of hardware defects. Refurbished spares are a practical way to keep legacy IBM storage shelves operational, extend lifecycle, and reduce electronic waste while controlling budget compared to buying new.

All refurbished hardware from Direct Hardware Supply includes a one-year warranty from the date of purchase (batteries, tape drives and tape libraries: three-month warranty). Extended warranty options are available on request. For broader IBM platform builds, you can also source complementary items like RISER CARD components and other IBM hardware as part of a complete maintenance plan.
