Equipped with two redundant field-replaceable 650W AC power supplies (90-264 VAC input), typical consumption 182W at 10% traffic, maximum 489W. Five field-replaceable fans with front-to-back airflow (134 CFM), operating temperature -5°C to 50°C, and acoustic noise of 52 dBA at 25°C.

What scaling capabilities does the switch support?

Supports up to 96,000 MAC addresses, 4,096 VLANs, 48,000 IPv4 unicast routes, 16,000 IPv6 routes, and 80,000 total routes in hardware. Additional features include 2,000 ACLs, 36 standard LAG members, mLAG spanning 2 switches, and 8 per-port priority pause levels.

What are the physical dimensions and environmental specs?

1U rackmount form factor, dimensions 44.0 cm W x 44.5 cm D x 4.37 cm H (17.3 x 17.5 x 1.72 in), weight 9.00 kg (19.8 lb). Operating humidity 5% to 95% non-condensing, altitude up to 4,000 m, storage -40°C to 70°C, MTBF 324,414 hours at 25°C.

Is it suitable for datacenter top-of-rack deployment?

Yes, designed as a fixed 25/100 GbE top-of-rack leaf switch with high-density ports, 3.6 Tbps throughput, low latency, and redundant components. Ideal for scale-out fabrics handling east-west traffic in virtualized or cloud environments with support for advanced L2/L3 features.
