Overview & Thematic Scope

Welcome to the comprehensive FAQ guide for storage expansion enclosures. Whether you are a network architect planning a capacity upgrade or a field engineer troubleshooting a deployment, this article addresses the critical pre-sales and post-sales questions we receive from professionals. We cover hardware specifications, compatibility, field-replaceable unit (FRU) procedures, and integration with existing systems. This guide is designed to provide definitive answers to ensure your storage scaling projects succeed.

Frequently Asked Questions

Q1: Does Telecomate offer storage expansion enclosures for data centers?

Yes, Telecomate offers a range of storage expansion enclosures designed to scale your existing storage infrastructure. These are not just empty chassis; they are high-performance modules like the 03033EMW expansion module, which features 4x100GE ports and a multi-core processor for high-throughput SAS disk array expansion . Additionally, Telecomate provides system motherboard boxes such as the 02357ADW, a 2U, 25-slot empty disk enclosure designed for custom drive population .

Q2: What are the physical specifications and rack unit (RU) sizes of these enclosures?

Telecomate enclosures are primarily available in standard 2U and 5U rack-mountable form factors. For instance, the 2U12 and 2U24 enclosures measure 87.90mm in height and approximately 630mm in depth, while the larger 5U84 models measure 220.00mm in height and 933.00mm in depth . These are designed to fit standard 19-inch racks, ensuring seamless integration into existing datacenter infrastructure .

Q3: What is the maximum drive capacity and backplane support for Telecomate storage enclosures?

Capacity depends on the specific model. High-density options include the 02352PAQ, a 2U controller enclosure supporting up to 25 disk drives . For expansion, the 03023PRM module supports a 12G SAS interface, offering high-bandwidth connectivity for scaling storage arrays . The enclosures also support system motherboard boxes like the 02357ADW, which is configured for 25 slots using 2.5-inch disk units .

Q4: How do I replace a field-replaceable unit (FRU) like a power supply or fan in an enclosure?

FRUs are designed for hot-swappable replacement to maintain uptime. For a power supply unit (PSU), ensure the partner PSU is functioning (no amber LED), retrieve the new unit, and replace the faulty one within a strict 7-minute window to prevent overheating . For fan cooling modules (FCM), the process involves releasing the latch, gently withdrawing the faulty module, and sliding the new one in until it locks. Always verify the green OK LED post-replacement .

Q5: What are the compatibility and substitution requirements for Telecomate enclosure parts?

When replacing components, it is critical to check for unidirectional or complete substitution compatibility. For example, the system motherboard box BOM 02357ADW is a unidirectional substitute for 02352XLV, meaning it can replace the older part but not vice versa . Similarly, the expansion module 03033EMW is a finished board specifically designed for OceanStor models like the 5500F V5 and Dorado 6000 V6 series .

Q6: What are the critical safety and installation warnings I need to know?

Always use a mechanical lift for installation—never attempt manual lifting of a fully populated chassis . Install enclosures from the bottom of the rack to the top to prevent tipping. It is critical that if you remove a FRU while the enclosure is powered up, you must replace it within the allotted time (e.g., 7 minutes for a PSU) to avoid voiding the warranty and causing overheating or data loss .

Q7: Is thermal management a concern for these expansion enclosures?

Yes, thermal management is a critical operational aspect. Telecomate enclosures feature redundant and replaceable fan cooling modules (FCMs) to ensure proper airflow . Removing a power supply unit (PSU) for extended periods significantly reduces airflow, which is why the replacement time limit is strictly enforced to prevent overheating and potential equipment failure .
