Vertiv SC127948 79-Inch Side CAR Rack Enclosure Extension
Overview
The Vertiv SC127948 is a 79-inch-tall side cabinet accessory (CAR) measuring 12 inches wide by 48 inches deep, designed to extend the usable space alongside compatible Vertiv Enclosure System (ES) racks. If your data center row or server room uses Vertiv Vertiv rack enclosures and you need structured side capacity for cable management, PDUs, or ancillary equipment without breaking into the primary rack footprint, the SC127948 is the purpose-built fit. It matches the 79-inch height profile of the compatible ES family, keeping your row at a consistent elevation — no mismatched panel gaps, no improvised filler panels.
Key Features
- 79″H × 12″W × 48″D Form Factor: The 12-inch width is purpose-sized for side-cable management runs or shallow ancillary hardware — narrow enough to avoid consuming a full rack bay, deep enough at 48 inches to align flush with full-depth rack enclosures in your row.
- Matched ES Compatibility: The SC127948 is verified compatible with the 79-inch, 48-inch-deep ES enclosure family — including SC127948, SC67948, and SCP7948 — so you can plan a consistent row without guessing fit. If your site runs the 42-inch-deep ES variant instead, the SC127942 is the correct alternate; confirm your ES depth before ordering.
- Row Coherence: Matching height across your cabinet row matters for blanking panels, airflow containment, and physical security — a side CAR that matches the ES height keeps hot-aisle/cold-aisle containment intact without custom fabrication.
- Scalable Family: Vertiv's ES CAR lineup spans 79″, 84″, and 91″ heights in both 42″ and 48″ depths, so if your site later standardizes on a different ES height, the side CAR upgrade path is clear within the same product family.
Integration and Compatibility
According to manufacturer specifications, the SC127948 is compatible with the following Vertiv ES enclosure models at the 79-inch height: SC127948, SC67948, and SCP7948 (all 79″H × 48″D ES). It is also cross-referenced alongside LRB-12, LRB-12A1, LRB-12A2, LRB-24, LRB-24A1, and LRB-24A2 accessories, which are listed as compatible across all ES sizes. If your deployment uses rack accessories from the LRB series, confirm compatibility against your specific ES model prior to installation. For the 42-inch-depth ES variants at the same 79-inch height, specify SC127942, SC67942, or SCP7942 instead of SC127948 — depth mismatch is the most common ordering error on this product line.
Frequently Asked Questions
Q: What Vertiv ES enclosure models is the SC127948 compatible with?
A: The SC127948 is compatible with Vertiv ES enclosures at the 79-inch height and 48-inch depth — specifically SC127948, SC67948, and SCP7948. It is not designed for 42-inch-depth ES enclosures; for those, the correct part is SC127942.
Q: What are the exact dimensions of the SC127948?
A: The SC127948 measures 79 inches high, 12 inches wide, and 48 inches deep.
Q: Will the SC127948 work with Vertiv LRB-series accessories?
A: Yes — the LRB-12, LRB-12A1, LRB-12A2, LRB-24, LRB-24A1, and LRB-24A2 accessories are listed as compatible with all ES sizes, including the ES enclosures that pair with the SC127948.
Q: What is the difference between the SC127948 and the SC127942?
A: Both are 79-inch-tall Side CARs, but the SC127948 is 48 inches deep and the SC127942 is 42 inches deep. Match the depth to your ES enclosure to ensure flush alignment in the row.
The SC127948 is a 79″H × 12″W × 48″D Side CAR — and the depth dimension is the critical number. At 48 inches, it aligns flush with full-depth ES enclosures in the row. I've seen sites order the 42-inch variant and end up with a 6-inch gap at the rear that breaks airflow containment and forces a custom filler. Verify your ES depth before you finalize the PO.
Technical Highlights:
- 12-Inch Width: Narrow enough to avoid consuming a standard 19-inch or 23-inch rack bay — keeps side cable management or shallow gear out of your primary equipment space.
- 48-Inch Depth: Matches full-depth ES enclosures exactly, so hot-aisle/cold-aisle containment systems close cleanly at the row end without gaps or panel adapters.
- ES Family Alignment: Compatible across SC127948, SC67948, and SCP7948 — the three ES variants at 79-inch height and 48-inch depth — so it integrates consistently whether your baseline enclosure is a standard, short, or performance ES configuration.
Deployment Considerations:
- Confirm your ES enclosure's depth is 48 inches before ordering — the 42-inch-depth ES family requires SC127942, not SC127948. This is the most common ordering mistake on this product line.
- If LRB-series cable management arms are already deployed on your ES enclosures, verify LRB compatibility against your specific ES model since the LRB line is listed as compatible with all ES sizes — but installation clearance with the side CAR in place should be confirmed at the rack level.
The SC127948 is the right call for data center rows where full-depth Vertiv ES enclosures are already standardized and you need flush, height-matched side capacity — particularly where airflow containment is engineered and a 6-inch depth mismatch would require custom panel work to close.
