RackSwitch G8000
Product Guide
The RackSwitch™ G8000 (Figure 1) is a top-of-rack (TOR) switch that delivers unmatched line-rate Layer 2/3
performance at a very attractive price. The G8000 is prepared for network virtualization, airflow to match server
racks, and low power consumption, making it an ideal choice for the next-generation data centers. It has forty-four
1 GbE RJ-45 ports, four 1 Gb SFP ports, and standard redundant power supplies along with up to four optional 10
GbE SFP+ or CX4 ports. Unlike most rack equipment that cools from side to side, the RackSwitch G8000 has rear-
to-front airflow or front-to-rear that matches server airflow.

VMready® switch-resident software reduces the complexity of configuring and managing virtual machines
throughout the network.
Networking Operating System (Networking OS) software features deliver seamless, standards-based integration
into existing upstream switches.
The RackSwitch G8000 supports stacking for up to six switches using a single switch image and configuration file
that shares one IP address and one management interface.

** The option is not available for MTM 7309-HCC. Supported cables and transceivers With the flexibility of the G8000 switch, clients can take advantage of the technologies that they require for multiple environments: For 1 GbE links, clients can use RJ-45 UTP cables up to 100 m. Clients that need longer distances can leverage the SFP ports by using a 1000BASE-SX transceiver, which can drive distances up to 220 meters by using 62.5 µ... - Page 4 15 m. The RackSwitch G8000 switch supports 10 GbE links with the optional dual-port SFP+ or CX4 uplink modules (see Table 3). Up to two uplink modules can be installed per switch (one on the front panel and one on the rear panel).
