Aggregation layers in large campuses usually run out of rack space before they run out of bandwidth. The S6750-H36C answers that directly: thirty-six 100GE QSFP28 ports in a single rack unit, 8 Tbps of system switching capacity, and dual pluggable 1200 W power supplies for 1+1 redundancy — all in a chassis 43.6 mm tall.
What separates it from a generic high-density switch is MACsec. Ethernet frames are authenticated, encrypted, integrity-checked and protected against replay at the link layer, which is what government, banking and defence tenders in the Kingdom increasingly ask for by name. Note the constraint: MACsec runs on ports 1–16 or ports 25–36, so the encrypted links must be planned into the port map at design stage, not patched in afterwards.

Where it fits best
Aggregation layer in large enterprise campuses, universities and data centres — and in particular any deployment where encrypted links are a tender requirement. Two numbers deserve attention before the room is chosen: the 45 °C operating ceiling, and the 86.4 dB(A) noise figure at high temperature. This switch belongs in a properly cooled room, not a converted office cupboard.
Service: Fast Vision supplies, configures, stacks and warranties this switch as an authorised Huawei distributor in Saudi Arabia.
