EX2500 Ethernet Switch Overview
The EX2500 Ethernet Switch is an all 10-Gigabit Ethernet rackable aggregation
switch. The EX2500 switch uses a wire-speed, non-blocking switching fabric that
provides simultaneous wire-speed transport of multiple packets at low latency on
all ports.
The EX2500 switch contains 24 10-gigabit Small Form-Factor Pluggable Plus
(SFP+) ports and 2 1-gigabit management ports. The 10-gigabit SFP+ ports can
accept 10-gigabit optical transceivers or Direct Attach Cables (DACs).
This 1U switch is rack mountable in either the horizontal or vertical direction,
depending on your application.
You can manage the switch through the console port, or through a network
connection using Telnet, a Web Device Manager, or SNMP-based network
management software.

Ports
The switch unit (Figure 1 and Figure 2) contains 24 10-gigabit SFP+ ports, plus
2 management ports, and 1 serial console port:
24 SFP+ ports
2 RJ-45 management ports
1 RS-232 console port (mini-USB)

Reset Button
The RESET button is recessed within a hole on the front panel. Use a straightened
paper clip or similar object to press the RESET button. The RESET button allows
technicians to reset the switch, as follows:
Press RESET—The switch resets and reloads the configuration files.
Press and hold RESET for 5 seconds—The switch resets and configures all
settings to factory defaults.
Fans
Six internal fans cool the switch unit. If an individual fan fails, the other fans
continue to run, and the switch unit continues to operate normally. Fans are not
customer replaceable.

Chapter 1: EX2500 Ethernet Switch Description and Specifications
Fan operation and internal temperatures are monitored. If the air temperature
exceeds a desired threshold, the environmental monitor displays warning
messages.
The FAN LED blinks if there is a failure of one or more fans.
Power Supplies
The EX2500 switch has two redundant 275W AC power supplies. Each internal
power supply has an individual IEC 320 power connector on the rear panel
(Figure 2 on page 4). The power cord attaches to a universal grounded AC power
source.
Each power supply can be connected to a separate AC circuit to mitigate the risk of
down time during a power failure. When used in a redundant configuration, the
dual power supplies have a load-sharing capability that allows each 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 supply by operating normally in a conservative power
mode.
There is no power switch on the EX2500 switch; the switch unit powers on when
power is supplied through the power cord(s).
The SYS LED indicates the status of the power supplies. The LED blinks when only
one power cord is connected or if one power supply fails. The LED lights steadily
when both power cords are connected and operating.
Switch Ports
The EX2500 switch has 24 SFP+ ports, 2 management ports, and 1 console port.
SFP+ Ports
24 Small Form-Factor Pluggable (SFP+) ports are located on the front panel. These
ports accept approved optical SFP+ transceivers or direct access cables (DACs).
Transceivers and DACs are not included with the EX2500 switch unit. Table 4 lists
the transceivers and DACs that are approved by Juniper Networks for use with the
switch.
CAUTION: If a fan fails, the maximum operating temperature drops from +40ºC to
+35ºC.
WARNING: To reduce the risk of electric shock, use only power cords that have a
grounding path, and always connect the power cord to a properly grounded
power outlet.
