Router modules
1
• 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, you 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, you 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 you are using 2100W AC power supplies, five are required and three are redundant
(200-240 volts AC only).
- If you are using 2400W AC or 2400W DC power supplies, four are required and four are
redundant (200-240 volts AC only).
- If you are using 2100W and 2400W power supplies (AC or DC) in combination, five are
required and three are redundant.
- If you are 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.
Power supply interoperability
For Brocade MLXe routers, power supplies for the 4-slot, 8-slot, and 16-slot devices are
interchangeable. Power supplies for the Brocade MLXe 32-slot devices cannot be used in Brocade
MLXe 4-slot, 8-slot, or 16-slot devices.
For Brocade MLX Series and Brocade NetIron XMR 32-slot devices, you can mix 2400W and
3000W power supply units.
For Brocade MLX and Brocade NetIron XMR devices, only the 8-slot and 16-slot router power
supplies are interchangeable. The 4-slot and 32-slot power supplies cannot be used in 8-slot or
16-slot Brocade MLX or Brocade NetIron XMR devices.
For power supply specifications, refer to “Power specifications” on page 384.
Power supplies are installed in slots along the bottom of 8-slot, 16-slot, and 32-slot routers. Power
supplies are installed in slots in the rear of 4-slot routers.
Power supplies provide power to all router components, share the workload equally, and report
status to the management module. If the management module detects that a power supply has
failed or overheated, the management module redistributes the workload of the failed power
supply to the remaining power supplies.
Power supplies generally have three LEDs on the faceplate that provide status for input power,
output power, and notification of alarms. If the input power and output power LEDs are on (steady
green), the power supply is providing power to the router components. For more information about
power supply LEDs, refer to the AC and DC power supply sections in Table 39 on page 229.
