C1-N3K-C3172TQ-XL is the higher-power and heavier Nexus 3172 configuration. The official table lists three-hundred-sixty-watt typical power, four-hundred-forty-watt maximum power and a twenty-two-pound chassis. Those infrastructure requirements distinguish it from C1-N3K-C3172PQ-XL despite their shared memory and dual-supply design.
