Juniper EX4600 Hardware Guide

NOTE: If you have a Juniper Care service contract, register any addion, change, or upgrade of
hardware components at hps://www.juniper.net/customers/support/tools/updateinstallbase/ .
Failure to do so can result in signicant delays if you need replacement parts. This note does not
apply if you replace exisng components with the same type of component.

Port Panel of an EX4600 Switch
The xed poron of the port panel of the EX4600-40F switch supports up to a maximum of 40 logical
10 GbE ports. Twenty-four physical ports (0 through 23) support 10 Gbps small form-factor pluggable
plus (SFP+) transceivers. These ports can be congured as access ports. See The Hardware Compability
Tool for a list of supported transceivers. All 24 of these ports can be used for SFP+ transceivers or SFP+
direct aach copper (DAC) cables. You can use 1-Gigabit Ethernet SFP+ transceivers, 10-
Gigabit Ethernet SFP+ transceivers, and SFP+ direct aach copper cables in any access port.
The remaining 16 logical ports are available for four 40 GbE ports (24 through 27) that support up to
four quad small-form factor pluggable plus (QSFP+) transceivers. Each QSFP+ port can operate either as
a single 40 Gbps port or as a set of 4 independent 10 Gbps ports using QSFP+ breakout cables. The 40
GbE ports can be congured as either access ports or as uplinks. .
CAUTION: When you use the latest OEM part number FCLF8521P2BTL (printed on
the transceiver label), you can install 1GbE transceivers (such as QFX-SFP-1GE-T) in any
port with no restricons. The same applies for devices that support 10GbE copper
transceivers. However, if you are using the older OEM part number SP7041-M1-JN (not
shipped in last 3+ years) instead, do not install 1GbE copper transceivers (such as QFX-
SFP-1GE-T) directly above or below another 1GbE copper transceiver. Use only the top
row or boom row to avoid damage to the device caused when the transceivers are
installed above or below each other.
