Downlink Ports; Lan Interconnect Module Uplink Ports - HP 279720-B21 - ProLiant BL p-Class F-GbE Interconnect Overview

Users can independently disable or enable the switch ports as desired. Auto-MDI/MDIX with auto-
negotiation of speed and duplex mode is supported. Each GbE Interconnect Switch includes the
following Ethernet ports:
Sixteen dedicated internal 10/100 Mb/s Ethernet downlink ports connecting the server NICs to the
switch.
Six external Ethernet ports for data, interconnect switch A and B management, Integrated Lights-out
(iLO) management, and/or pre-boot execution environment (PXE) remote configuration.
– Two 10/100/1000T and two 10/100T uplink ports (C-GbE) or two 1000SX and two 10/100T
uplink ports (F-GbE) on the rear-mounted LAN interconnect module.
– Two 10/100T ports on the switch front panel.
Two dedicated internal 10/100 Mb/s Ethernet crosslink ports bundled as a multi-port trunk for
switch-to-switch communication and failover, if desired.
These Ethernet ports are described in the following subsections.

Downlink ports

Each GbE Interconnect Switch includes sixteen pre-assigned, internal 10/100 Mb/s Ethernet
downlink ports connecting the server blade network adapters signals to the switch. The signals are
routed as Ethernet from the server blades, across individual category 5e (CAT5e) specified signal
traces on the passive backplane assembly of the server blade enclosure, and then to the switches.

LAN interconnect module uplink ports

The LAN interconnect module uplink ports are typically used to connect the interconnect switches to
the network infrastructure; however, they are standard Ethernet switch ports and may be used as
desired. The GbE interconnect kits are identical with exception of the LAN interconnect modules. The
C-GbE Interconnect Kit includes two QuadT interconnect modules, each with two 10/100/1000T
