Lenovo RackSwitch G7052
Product Guide (withdrawn product)
The Lenovo RackSwitch G7052 is a low-cost, entry-level Layer 2 1/10 Gb Ethernet switch that is designed for the data center. Data center customers continue to deploy applications by using 1 GbE networking switches while 10 GbE continues to grow upstream in the network as clients require greater I/O bandwidth. The RackSwitch G7052 is an ideal solution for data center customers who need an economical 1 Gb and 10 Gb connectivity solution.
The RackSwitch G7052 (see the following figure) is a top-of-rack data center switch that delivers excellent non-blocking, wire speed performance at an attractive price point. It supports 48x 10/100/1000BASE-T RJ-45 ports and four 10 Gigabit Ethernet SFP+ ports standard, while typically using only 76 watts of power. The RackSwitch G7052 is also designed with rear-to-front airflow, which allows for flexible mounting of the switch in a rack cabinet and provides convenient cable management and significant savings in cooling costs.

Did you know?
The RackSwitch G7052 is designed with performance in mind with latency at 3.3 microseconds.
The RackSwitch G7052 supports an optional external redundant power supply with the Lenovo RackSwitch G7000 Redundant Power Supply (RPS) option.
The RackSwitch G7052 is designed specifically for the data center environment with server-matching airflow, cost-effective Layer 2 switching, and ease of configuration management.
Networking Operating System software features deliver seamless, standards- based integration into existing upstream switches.

Key features

The RackSwitch G7052 switch is considered particularly suited for the following customers:

• Customers who want to use GbE in their infrastructure (servers and networking)

• Customers who are implementing a virtualized environment and require multiple GbE ports Customers who require investment protection for 10 GbE ports

• Customers who want to reduce total cost of ownership (TCO) and improve performance while maintaining high levels of availability and security

• Customers who want to avoid or minimize oversubscription, which can result in congestion and loss of performance

• Customers who want to implement a converged infrastructure with NAS or iSCSI
  The switch offers the following key features and benefits:

• Increases network performance
  The RackSwitch G7052 provides up to 176 Gbps of switching throughput, supports four SFP+ 10 Gb uplink ports, and has a port to port latency of 3.3 microseconds.

• Lower power and exceptional cooling
  The RackSwitch G7052 typically uses only 76 W of power. Unlike side-cooled switches, which can cause heat recirculation and reliability concerns, the RackSwitch G7052 switch’s rear-to-front cooling design reduces data center air conditioning costs by matching airflow to the server’s configuration in the rack.

• Fault tolerance
  These switches learn alternative paths automatically and perform faster convergence if there is a link, switch, or power failure. The switch uses technologies, such as Virtual Link Aggregation, L2 trunk failover, and Hot Links.

• Seamless interoperability}
  RackSwitch switches interoperate seamlessly with other vendors’ upstream switches.

The RackSwitch G7052 supports an optional external redundant power supply with the Lenovo RackSwitch G7000 Redundant Power Supply (RPS) option that is shown in the following figure.

Figure 2. Lenovo RackSwitch G7000 Redundant Power Supply
The G7000 RPS option has the following features:

• Form factor: 1U rack mount
• Power connections: Four DC connections in the rear of the rack to connect to the G7028 and G7052 switches; one AC inlet connector to connect to the power source (rack PDU or wall connector)
• Airflow: Rear-to-front cooling
• Power: Approximately 55 – 276 W, which varies depending upon operating conditions and number and types of switches connected
• Rack installation: Generic rack-mount kit (2-post); optional flexible 4-post mounting option for the server rack and the communications rack
• LEDs: System LEDs to indicate status

• For 10 GbE links (supported on SFP+ ports), customers can use direct-attached copper (DAC) SFP+ cables for in-rack cabling for distances up to 7 meters or SFP+ active optical cables (AOCs) for distances up to 20 meters. These cables have SFP+ connectors on each end, and they do not need separate transceivers. For distances up to 30 meters, the 10GBASE-T SFP+ transceiver can be used with Category 6a or 7 RJ-45 UTP cables.
  For longer distances, the 10GBASE-SR transceiver can support distances up to 300 meters over OM3 multimode fiber or up to 400 meters over OM4 multimode fiber. The 10GBASE-LR transceivers can support distances up to 10 kilometers on single mode fiber.

Warranty and maintenance

The RackSwitch G7052 comes with a 3-year Customer Replaceable Unit (CRU) hardware limited warranty with 9×5 Next Business Day (NBD) Parts Delivered and includes a 3-year software license, which provides entitlement to upgrades over that period. The options that are installed in the switch assume the switch’s base warranty and any Lenovo warranty service upgrade for the switch.
Some regions might have different warranty terms and conditions than the standard warranty. This is due to local business practices or laws in the specific region. Local service teams can assist in explaining region-specific terms when needed. Examples of region-specific warranty terms are second or longer business day parts delivery or parts-only base warranty.
If warranty terms and conditions include onsite labor for repair or replacement of parts, Lenovo will dispatch a service technician to the customer site to perform the replacement. Onsite labor under base warranty is limited to labor for replacement of parts that have been determined to be field-replaceable units (FRUs). Parts that are determined to be customer- replaceable units (CRUs) do not include onsite labor under base warranty.
If warranty terms include parts-only base warranty, Lenovo is responsible for delivering only replacement parts that are under base warranty (including FRUs) that will be sent to a requested location for self-service. Parts-only service does not include a service technician being dispatched onsite. Parts must be changed at customer’s own cost and labor and defective parts must be returned following the instructions supplied with the spares parts.
Also available are Lenovo Services warranty maintenance upgrades and post- warranty maintenance agreements, with a well-defined scope of services, including service hours, response time, term of service, and service agreement terms and conditions.
Lenovo warranty service upgrade offerings are region-specific. Not all warranty service upgrades are available in every region. For information about Lenovo warranty service upgrade offerings that are available in your region, refer to the following resources:

• Service part numbers in Lenovo Data Center Solutions Configurator (DCSC):
  http://dcsc.lenovo.com/#/services

• Lenovo Services Availability Locator

In general, the following Lenovo warranty service upgrades are available:

• Warranty and maintenance service upgrades:

  • 3, 4, or 5 years of warranty service coverage
  • 1-year or 2-year post-warranty extensions
  • Foundation Service: 9×5 service coverage with next business day onsite response
  • Essential Service: 24×7 service coverage with 4-hour onsite response or 24-hour committed repair (available only in select regions)
  • Advanced Service: 24×7 service coverage with 2-hour onsite response or 6-hour committed repair (available only in select regions)

• Premier Support

• Basic Hardware Installation Services
  Lenovo experts can seamlessly manage the physical installation of your server, storage, or networking hardware. Working at a time convenient for you (business hours or off shift), the technician will unpack and inspect the systems on your site, install options, mount in a rack cabinet, connect to power and network, check and update firmware to the latest levels, verify operation, and dispose of the packaging, allowing your team to focus on other priorities.
