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.

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.

„
EX2500 Ethernet Switch Components
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.
CAUTION: If a fan fails, the maximum operating temperature drops from +40ºC to
+35ºC.
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.
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.
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.

Connecting Power to the EX2500 Ethernet Switch
WARNING: The EX2500 switch does not have a power switch. When you connect
one of the two power cords to a suitable, energized AC power outlet, the switch
powers on immediately. You must disconnect the power cords to power off the
EX2500 switch. Always connect each power cord to a universal grounded power
source in a location that is quickly and safely accessible.
The EX2500 Ethernet Switch has two AC power supplies, each with its own IEC 320
power connector. When connected to separate AC circuits, the dual power supplies
share the power load to mitigate the risk of down time during a power failure. To
connect power to the switch:
1. Connect one AC power cord to one of the two IEC 320 power connections on
the rear panel of the switch, and connect the second power cord to the other
IEC connector.
2. If the AC power source outlets have a power switch, set each outlet switch to
the OFF (0) position.
3. Insert one power cord into one AC power source outlet, and then insert the
second power cord into an AC power source on a separate circuit.
If the outlet does not have a power switch, the switch powers on immediately.
4. If the AC power source outlets have a power switch, set each outlet switch to
the ON (|) position.
The switch powers on immediately.
5. Verify overall system status:
„
SYS—Must be solid green if both power cords are connected, or blinking
green if only one power cord is connected
„
FAN—Must be solid green if all fans are running.
CAUTION: A blinking green FAN LED indicates a fan failure. Contact Juniper
Networks technical support.
Initializing the EX2500 Ethernet Switch

Initializing the EX2500 Ethernet Switch
„
19
EX2500 Ethernet Switch Hardware Guide
To configure an IP interface:
1. Log in to the switch.
2. Enter Global Configuration mode.
ex2500> enable
ex2500# configure terminal
3. Configure the management IP address, subnet mask, and gateway. For
example:
ex2500(config)# interface ip-mgmt address 10.10.10.2
ex2500(config)# interface ip-mgmt netmask 255.255.255.0
ex2500(config)# interface ip-mgmt enable
ex2500(config)# interface ip-mgmt gateway 10.10.10.1
ex2500(config)# interface ip-mgmt gateway enable
ex2500(config)# exit
Once you configure the IP address for your switch, you can connect to the
management port and use the Telnet program from an external management
station to access and control the switch. The management station and your switch
must be on the same IP subnet.
The EX2500 switch supports a command-line interface (CLI) that you can use to
configure and control the switch using Telnet. You can use the CLI to perform many
basic network management functions. In addition, you can configure the switch for
management using an SNMP-based network management system or a Web
browser.
For more information about using the CLI, see the EX2500 Ethernet Switch
Command Reference.
