JL670A - Aruba X372 54VDC 1600W 110-240VAC Power Supply

Aruba JL670A — X372 54VDC 1600W Power Supply (high-line, PoE-capable) for CX 6300

What it is

JL670A isn’t a switch — it’s a power supply module.
It’s the Aruba X372 54VDC 1600W hot-plug AC PSU designed for Aruba CX 6300 PoE-capable switches. This is the “big PoE budget” supply: it powers the system and provides a large 54V rail for PoE.

Why buyers pick JL670A (plain English)

• Max PoE power for CX 6300 closets
  Built to support heavy PoE loads (lots of APs/phones/cameras) on 6300 PoE models.

• Redundancy and load sharing
  CX 6300 supports dual PSUs — adding JL670A gives N+1 resiliency and increases overall PoE pool.

• Hot-plug serviceability
  Swap or add without shutting down the switch (as long as another PSU is present).

• Correct PoE keying
  PoE-keyed PSU so it won’t fit non-PoE chassis, preventing mismatches.

Type

• Hot-plug AC power supply for Aruba CX 6300 PoE platforms

Total output power

• 1600W

Output rail

• 54VDC (system + PoE)

PoE contribution

• Up to ~1440W PoE budget available to the switch (platform/PSU-count dependent)

Input power

• High-line only (typically 200–240VAC)

• Auto-ranging within high-line range

Cooling

• Integrated PSU fan (chassis-managed)

Compatibility (common use)

• Aruba CX 6300 PoE switch models (6300F/6300M PoE variants)

Where it fits (and when to choose something else)

Perfect for:

• CX 6300 deployments that need large PoE+ / PoE budgets

• Adding redundancy or boosting PoE pool capacity

• Replacing a failed high-watt PoE PSU in a CX 6300

Choose something else if:

• You’re on non-PoE CX 6300 → use the non-PoE PSU option for that chassis

• You don’t have high-line power available → pick a PSU that supports low-line (if your model allows)

TL;DR

JL670A is the Aruba X372 1600W 54VDC hot-plug PoE power supply for CX 6300:
high-line AC input, big PoE budget, and designed for redundant, PoE-heavy 6300 access/edge stacks.
