High-speed switch fabric modules
Generation 2 (G2) high-speed fabric (HSF) modules support wire-speed forwarding for all packet
sizes, including jumbo frames.
HSF modules are supported on PowerConnect B-MLXe routers and are interoperable with all
existing interface modules.
HSF modules are hot-swappable, which allows you to install or replace them while the system is
powered up and running.
Power supplies
PowerConnect B-MLXe routers support the following power supply options:
•
•
•
For power supply specifications, refer to
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 have three LEDs on the faceplate. These LEDs provide status for input power,
output power, and notification of alarms that have been sent. If the input power and output power
LEDs are on (a steady green), the power supply is providing power to the router components. For
more information about the power supply LEDs, refer to the AC power supply sections in
on page 207.
NOTE
After a power supply is removed from a router, the software determines if there is enough power to
operate all of the interface modules. If it determines that there is not enough power, some interface
modules will be powered off.
DANGER
Power supplies are hot-swappable, which means they can be removed and replaced while the
router is powered on and running. However, Dell recommends that you disconnect a power
supply from its power source before removing and replacing the supply. The 4-, 8-, and 16-slot

4-slot router: Ships with one power supply, but can accommodate three AC power supplies (one
required and two redundant). To equip your router for redundancy, you must purchase one or
two additional power supplies.
8-slot router: Accommodates four AC power supplies (two required and two redundant).
Because power is supplied over a common power bus, any power supply installed in addition to
the two required will provide backup for any supply that fails. For full redundancy for both of the
required power supplies, you must add two additional power supplies.
16-slot router: Accommodates eight AC power supplies (four required and four redundant).
Because power is supplied over a common power bus, any power supply installed in addition to
the four required will provide backup for any power supply that fails. For full redundancy for all
of the required power supplies, you must add four additional power supplies.
