=)E/.1)V !
Plexxi Switch 2e (Model: PX-S2E or S2E) is a Plexxi entry-series switch that supports scale-out
applications with high performance East-West traffic needs. Plexxi Switch 2e differs from the other
Plexxi Switch 2 models; it does not have the Plexxi LightRail™interface. Instead, it uses 1310nm waves
through the six QSFP interfaces to create a LightRail interface.
Each of the six QSFP interfaces supports 4x10GbE, making the total bandwidth identical to the LightRail
interfaces on other Switch 2 models (6x4x10GbE=24x10GbE).
@)3O.5W!-)PE.>1)236!
Plexxi Switch 2e network deployments include:
•PSI optical-based solution for six switches or more (four switch minimum)
Connect all Plexxi 2e switches to a Plexxi PSI Interconnect passive device. You plug each Switch 2e
into the PSI using the Plexxi-supplied cable. The passive PSI device creates the mesh structure of a
Plexxi network. You can deploy Switch 2 models 2p and 2sp with 2e in this network.
•Switch 2e Direct Connect for seven switches or less
Directly connect Plexxi 2e switches together using a QSFP-to-QSFP cable such as a Direct Attach
Cable (DAC) or Active Optical Cable (AOC). You cannot directly connect Plexxi 2e switches in a
network that includes Switch 2p and 2sp as well, or if the deployment is expected to grow beyond
seven switches.
;263<EE<37.2!X.267R)5<37.26!
Keep the following considerations in mind when installing your switches.
H.O)5!
•Make certain that all input connections are accessible at all times, and disconnect all power plugs
before servicing or moving the unit.
•Ensure that appropriate grounding and current surge protection are in place before connecting the
switch to a power source.
YP37/<E!X<8E)6!
•Avoid excessive bending, which can damage the cables — particularly optical cables.
•Ample clearance exists at the front and access port panels to allow unrestricted cabling.
•AC power cords can easily reach from the AC power outlet to the connection on the power supply panel
of the switch.

Warning: The primary hazards of exposure to invisible laser radiation from an optical fiber
communications system are:
ï Damage to the eye by viewing an unterminated optical fiber or fiber optic connector.
ï Damage to the eye from invisible laser radiation from viewing a cut fiber or a broken fiber.
Never attempt to view optical connectors that may be emitting laser energy and always avoid possible exposure to
invisible optical laser radiation. Using optical fiber scopes or magnifying lenses may increase the possibility for an
eye hazard. It is recommended that you use an optical power meter to determine if there is optical laser radiation
present or use a remote video display inspection tool to inspect connectors.
WARNING To avoid possible eye injury, use an optical power meter to ensure there is no
optical power in a cable connected to any Plexxi switch. Even if a switch is
powered off, passive optics in a Plexxi fabric may transmit eye-damaging
optical signals from neighboring switches.
! No user serviceable parts are inside the chassis other than the power supplies and
fan assemblies. Contact Plexxi for all repairs .
!Only qualified personnel should service or replace Plexxi Switches.
! The Plexxi Switch contains multiple separate power sources. Always make certain
that all power sources are disconnected before servicing the unit.
JE)/35.63<37/!-76/A<5T)!H5)/<037.26&
Use Electrostatic Discharge (ESD) precautions when handling a Plexxi Switch outside a data center rack.
Once the switch is installed in a rack, the mounting hardware provides grounding through the rack.
J?-!S07R)E72)6 &
Observe the following guidelines to avoid electrostatic discharge (ESD) damage when installing or
servicing the Plexxi Switch.
•Minimize handling of assemblies and components.
•Assemble or remove equipment only in a static-free work area.
•Use conductive work surfaces (such as an antistatic mat) to dissipate static charge and wear a
conductive wrist strap to dissipate the accumulation of static charge accumulation.
•Keep replacement parts in their original static-free packaging.
•Remove all plastic, foam, vinyl, paper, and other static-generating materials from the work area.
•Whenever possible, use tools that do not create electrostatic discharge.

Plexxi’s Pod Switch Interconnect (PSI) is a passive optical switch that uses Plexxi’s optical LightRail
interface to connect some of Plexxi Switch 2 models 2p, 2sp, and 2e into a meshed network.

You connect Plexxi PSI Interconnect LightRail ports to the Plexxi Switch 2e QSFP ports following the
West-to-East convention. You plug the 24-fiber connector into the Plexxi PSI Interconnect port and the
12-fiber side of the MTP connector to the QSFP ports on Plexxi Switch 2e.
You need to match the label number (1, 2, and 3) on the 12-fiber side of the MTP connectors with a
specific port number on Plexxi Switch 2e. You connect to the appropriate QSFP port in the direction,
West or East, that you need.

You can create a network topology that includes Switch 2e, Switch 2p and Switch 2sp when they are
attached to a PSI. The optics used in the QSFP slots that create the LightRail use 1310nm waves, which
makes Switch 2e LightRail compatible with these two pod versions of Plexxi Switches (Switch 2p, 2sp).
The following illustration shows a network topology that includes two Plexxi 2e switches and a Plexxi
Switch 2sp connected to Plexxi PSI Interconnect device. As shown, all unused ports are looped back.

You can directly connect Plexxi 2e switches together using a QSFP-to-QSFP cable such as DAC or

•Three type of connections are allowed between two Plexxi 2e switches:
W1-E1, W2-E2, W3-E3
QSFP DAC or AOC cables are connected from the top ports (W1, W2, W3) to the bottom ports (E1,
E2, E3), East and West ports of the same number are allowed to connect.
•Number the Plexxi 2e switches you want to connect starting with 1. For example, if you are
connecting five Plexxi 2e switches, number them 1, 2, 3, 4, 5. You can affix a label to the switch for
identification.
•Start the connection from Switch 2e 1, go on to Switch 2e 2 next, through to the last Switch 2e in the
Plexxi Ring fabric.
•Start connections from W1, then W2, then W3 for each Switch 2e.
•Connect W1 to E1, W2 to E2, and W3 to E3. For each switch, connect W1 to the next numbered
switch E1, W2 to the E2 port of the switch that comes next in order, and W3 to the E3 port of the
switch that comes next again in order. For example, you plug one end of the DAC or AOC cable in

Follow the guidelines described here to add a Switch 2e to an existing network, which requires recabling
the switches.
•Identify the numbers or order of the current Plexxi 2e switches in the existing ring fabric, which one
is 1, which one is 2, and so on.
•Make the Switch 2e you want to add to the ring fabric the last number/last in order.

You have an existing ring fabric with five Plexxi 2e switches. You want to add another switch 2e to make
it a ring fabric of six. To add the switch, you need to shift six existing connections and add three more
