A base configuration J-EX8208 switch has one SRE module. A redundant configuration
J-EX8208 switch has a second SRE module. See J-EX8208 Switch Configurations.
The Switch Fabric (SF) module, working with the SRE module, provides the necessary
switching functionality to a base configuration J-EX8208 switch. The SF module is
installed in the front of the chassis in the slot labeled SF. In a redundant configuration
the SF module provides a redundant switch fabric. The additional switch fabric provides
full 2+1 switch fabric redundancy to the switch. See Switch Fabric (SF) Module in a
J-EX8208 Switch.
Line Cards
The J-EX8208 switch features eight horizontal line card slots and supports the line rate
for each line card. The line cards in J-EX8200 switches combine a Packet Forwarding
Engine and Ethernet interfaces on a single assembly. They are field-replaceable units
(FRUs) that can be installed in the line card slots labeled 0 through 7 on the front of the
switch chassis. See Slot Numbering for a J-EX8208 Switch. All line cards are
hot-removable and hot-insertable.
The following line cards are available for J-EX8208 switches:
•
8-port 10-Gigabit Ethernet SFP+ line card: This line card has eight 10-gigabit SFP+
ports on its faceplate in which you can install SFP+ transceivers. See 8-port SFP+ Line
Card in a J-EX8200 Switch.
• 48-port 100/1000 SFP line card: This line card has 48 1-gigabit SFP ports on its
faceplate in which you can install SFP transceivers. See 48-port SFP Line Card in a
J-EX8200 Switch.
• 48-port 10/100/1000 RJ-45 line card: This line card had 48 10/100/1000 Gigabit
Ethernet ports with RJ-45 connectors on its faceplate. See 48-port RJ-45 Line Card in
a J-EX8200 Switch.
Cooling System
The cooling system in a J-EX8208 switch consists of a hot-removable and hot-insertable
fan tray. The fan tray contains 12 fans. The fan tray installs vertically on the left front of
the chassis and provides side-to-side chassis cooling. See Cooling System and Airflow
in a J-EX8208 Switch.
Power Supplies
Power supplies for the J-EX8208 switch are fully redundant, load-sharing, and
hot-removable and hot-insertable field-replaceable units (FRUs). Each J-EX8208 switch
chassis can hold up to six 2000 W AC power supplies.
The 2000 W AC power supplies support both low-voltage line (100–120 VAC) and
high-voltage line (200–240 VAC) AC power configurations on a J-EX8208 switch. Each
2000 W AC power supply delivers 2000 W of power at high voltage (200–240 VAC) or
1200 W at low voltage (100–120 VAC) to the J-EX8208 chassis.
