Two power supply modules are required for redundancy. Each power supply can be connected to a separate circuit to mitigate the risk of down‐time during a localized power failure. When used in a redundant configuration, the dual power supplies have a load‐sharing capability that enables each power supply to operate at approximately 50 percent of full load. Using redundant power can minimize the power disruption during a power supply failure and extend the expected lifetime of each power supply by operating normally in a conservative power mode. For proper airflow when operating the switch with only one power supply module, the empty power supply bay must be protected by a blank cover module. There is no power switch on the G8332 power modules; the switch powers up when power is supplied through the power cord to one or both power supplies. © Copyright Lenovo 2017 Chapter 2: Switch Components...

Page 83: Default Configuration Files
Default Configuration Files The switch firmware contains default configuration files that are loaded at the factory. When the switch first initializes, the default configuration files are loaded into the active switch memory. The default settings allow the switch to perform basic functions with minimal effort by the system administrator. Custom configuration settings made by the administrator will override the default settings and can be saved so that they are retained if the switch is rebooted. However, if desired, you can revert the custom configuration settings to the original factory defaults. The original factory default configuration files are a permanent part of the firmware; you cannot deleted them or change their original definitions. © Copyright Lenovo 2017 Chapter 5: Initializing the G8332...
Page 84: Configuring The Management Interface For Remote Access
 IP address and subnet mask  Gateway address By default, DHCP is enabled on the management interface. If there is no DHCP offer received, the switch uses the default management IP address (192.168.50.50/24). This address is overwritten when a DHCP address is received for that interface. If DHCP is enabled and there is no static address configured for DHCP, requests will continue to be sent. This feature does not change existing DHCP functionality. To configure the management interface for remote management, complete the following steps. 1. Log onto the switch using the serial console port or management port on the G8332 front panel. 2. Enter management interface mode.  for Lenovo Enterprise Network Operating System (ENOS): G8332> enable G8332# configure terminal G8332(config)# interface ip 128 G8332(configipif)#  for Lenovo Cloud Network Operating System (CNOS): G8332> enable G8332# configure device G8332(config)# interface mgmt 0 G8332(configif)# 3.

Page 106: Important Notes
Important Notes Processor speed indicates the internal clock speed of the microprocessor; other factors also affect application performance. CD or DVD drive speed is the variable read rate. Actual speeds vary and are often less than the possible maximum. When referring to processor storage, real and virtual storage, or channel volume, KB stands for 1,024 bytes, MB stands for 1,048,576 bytes and GB stands for 1,073,741,824 bytes. When referring to hard disk drive capacity or communications volume, MB stands for 1,000,000 bytes and GB stands for 1,000,000,000 bytes. Total user‐accessible capacity can vary depending on operating environments. Maximum internal hard disk drive capacities assume the replacement of any standard hard disk drives and population of all hard‐disk‐drive bays with the largest currently supported drives that are available from Lenovo. Maximum memory might require replacement of the standard memory with an optional memory module. Each solid‐state memory cell has an intrinsic, finite number of write cycles that the cell can incur. Therefore, a solid‐state device has a maximum number of write cycles that it can be subjected to, expressed as total bytes written (TBW). A device that has exceeded this limit might fail to respond to system‐generated commands or might be incapable of being written to. Lenovo is not responsible for replacement of a device that has exceeded its maximum guaranteed number of program/erase cycles, as documented in the Official Published Specifications for the device. Lenovo makes no representations or warranties with respect to non‐Lenovo products. Support (if any) for the non‐Lenovo products is provided by the third party, not Lenovo.
