BMC of T4048-IX2
T4048-IX2 has a built-in baseboard management controller (BMC) that plays the role of
monitoring the whole system. The BMC is an independent subsystem with its own processor and
memory so that it can run well even if the switch system hangs or powers down.
BMC Features
BMC supports the following features:
• Support IPMI v1.5 and v2.0 partial
• Serial over LAN
• HTTPS support
• Health status and hardware monitoring report
• Events log
• Event notication via LED indicator (on the chassis) and PET (Platform Event Trap)
• Platform Event Filtering (PEF) to perform the selected action
• Chassis management
• Watchdog, auto system re-start and auto recovery
To access BMC, the system allows the out-of-band management port which is shared between
the switch and BMC. The system administrator can manage BMC remotely via Web by entering
the its default IP address. By default, the BMC IP address is pre-congured to 192.168.0.120.
[BMC default IP address]
192.168.0.120
BMC supports two network connection options: Static IP and DHCP. For static IP connection, the
administrator can change the BMC IP address via Web. Once the IP address is changed, re-login
is required.
The console port is set only for the switch conguration. Although the hidden pin is accessible
through the hole on the chassis, it is reserved specically for debugging purpose by the
manufacturer and is not intended for end users operation. The hidden pin is located in
between 38 and 39 port LEDs as shown in the illustration below.

Airow Direction
The switch ships with four fan modules and two AC power supplies. The direction of the airow
varies depending on the color of the fan module handle/plug retainer.
• Red: indicates front-to-back airow (air inlet module).
• Blue: indicates back-to-front airow (air outlet module).
• Do not mix power supplies and fan modules with dierent airow in the same
chassis.
CAUTION
Front-to-Back Airow
The air intake is located on the front panel of the switch. The cool air is sucked in from outside
the chassis and pushed toward the rear of the chassis. The hot air exhausts through the vents on
the rear panel of the switch.
