Additional notes
Brocade MLX Series and Brocade NetIron XMR routers support the following power supply options:
  • 4-slot router: Supports 1200W and 1800W AC and DC power supplies.
    • MLX and XMR devices can accommodate three 1200W power supplies. For power redundancy, users must purchase additional power supplies depending on how the router is populated.
    • MLXe devices can accommodate four 1200W or 1800W power supplies. For power redundancy, users must purchase additional power supplies depending on how the router is populated.
  • 8-slot router: Can accommodate up to four 1200W or 1800W AC and DC power supplies.
    • Because power is supplied over a common power bus, any power supply installed, in addition to the two required, provides backup for any supply that fails. For full redundancy for the required power supplies, users must add two additional power supplies.
  • 16-slot router: Can accommodate eight 1200W or 1800W AC and DC power supplies. Because power is supplied over a common power bus, any power supply installed, in addition to the four required, provides backup for any power supply that fails. For full redundancy for the required power supplies, users must add four additional power supplies.
NOTE: 1800W AC power supplies support low and high line operation. For line voltages between 90-180, the power supply operates at 1200W. For line voltages between 180-264, the power supply operates at 1800W.
  • 32-slot router: Supports 2100W AC, 2400W AC and DC, and 3000W AC and DC models.
    • Accommodates eight power supplies. The following redundancy configurations apply:
      • If using 2100W AC power supplies, five are required and three are redundant (200-240 volts AC only).
      • If using 2400W AC or 2400W DC power supplies, four are required and four are redundant (200-240 volts AC only).
      • If using 2100W and 2400W power supplies (AC or DC) in combination, five are required and three are redundant.
      • If using 3000W AC or DC power supplies, four are required and four are redundant. Because power is supplied over a common power bus, any power supply installed in addition to required power supplies provides backup for any power supply that fails
NOTE: The 2100W AC or DC power supply is no longer available.
