What is the form factor of the 3Com Switch 5500G-EI PSU 24?

It is an internal hot-swap power supply module designed for the Switch 5500G-EI 24-port chassis. This allows field replacement without system shutdown, integrating into the 440mm x 450mm 1U rack unit. Ideal for maintaining high availability in enterprise Gigabit networks with up to 184 Gbps switching capacity.

Is this PSU compatible with PoE configurations?

This is the standard AC PSU (3C17266) for non-PoE 24-port Switch 5500G-EI, consuming up to 74W. For PoE, use the dedicated 3C17264 PSU which supports up to 300W additional for powered devices. Both are hot-swappable in the same chassis for flexible upgrades.

What are the input power requirements?

Requires 90-240 VAC at 50/60 Hz with 3.0A maximum current. Supports AC/DC dual-input in chassis, with 74W max consumption for non-PoE 24-port model and 253 BTU/hour heat dissipation. Rated for 0-40°C operation up to 4572m altitude.

Does it support the full performance of the 24-port switch?

Yes, it powers the 24-port Switch 5500G-EI to 192 Gbps switching capacity base, upgradable to 184 Gbps with modules and 107.1 Mpps forwarding. Ensures wirespeed Gigabit performance across 24 ports plus 4 SFP combo ports without frame loss.

Can this PSU be used in 48-port models?

No, the PSU 24 (3C17266) is specified for 24-port Switch 5500G-EI chassis. 48-port models require the PSU 48 variant. Both are field-replaceable AC supplies, but chassis power stages differ for their respective port densities and capacities.

What is the SKU and product line?

SKU 3C17266 belongs to the Switch 5500G-EI product line as an AC power supply for 24-port models. It features enterprise-level reliability for Layer 3 Gigabit switches with expansion slots for SFP and 10G modules.
