Introduction
Thank you for purchasing the GigaX1048 switch! The GigaX1048 switch is a multi-port switch
designed for building a high-performance workgroup network. It features store-and-forward
switching architecture which reduces transmission latency and therefore offers high-speed
network exchange. With non-blocking and full wire-speed functions, you do not need to compete
with other users for bandwidth. The GigaX1048 switch has forty-eight RJ-45 10/100Mbps ports,
one RJ-45 10/100/1000Mbps port and one Mini GBIC port for esay connection to a Gigabit
network backbone.The GigaX1048 switch is a perfect choice for a department workgroup or
backbone network for a Small & Medium Business (SMB) enterprise.

Hardware description
This section introduces the physical features of the GigaX1048 switch and its installation
procedure.
Front panel
The front panel of GigaX1048 switch features forty-eight RJ-45 10/100Mbps ports (auto MDI/
MDIX), one RJ-45 10/100/100Mbps port, one Mini GBIC slot for fiber connection, and LED
indicators that indicate the condition of the switch.
Figure 1. Front panel
RJ-45 Ports (Auto MDI/MDIX):
The forty-eight RJ-45 10/100Mbps ports are auto MDI/MDIX
ready. Auto MDI/MDIX means that you can connect any compatible networking devices (e.g.
workstation, PC, switch, hub, etc.) using either a straight or cross-over Ethernet cable. Some
early models require straight and crossover cable for connecting different devices.
Gigabit port:
1 x 10/100/1000Mbps UTP port
1 x Mini GBIC slot.
Note:
Mini GBIC module is optional.
LED indicators
The LED indicators provide real-time information of operation status. The following table
provides descriptions of LED status and their meaning.

Rear panel
The three-pronged power plug is located at the rear panel of the GigaX1048 switch. The input
voltage is 100-240V AC with 50-60Hz frequency. The power plug includes a fuse (
ø5mm x 20mm
2A/250V Max.
) that prevents damage to the switch due to unstable voltage. The fuse could be
replaced when busted.

Desktop installation
Attaching rubber stands
1. Place the switch on a stable and dust-free surface.
2. Remove the adhesive cover from a rubber stand.
3. Attach the rubber stand to one corner at the bottom of the switch.
4. Repeat steps 2 and 3 to place the other rubber stands.
Rack mount
The ASUS GigaX1048 switch comes with a rack mount kit that can be fitted into an EIA
standard 19-inch rack. The switch can be placed in a wire closet with other equipments.
Follow these steps to mount the switch onto a rack:
1. Use small screws to secure mounting brackets to the holes on both sides of the switch.
2. Position the ASUS GigaX1048 onto the rack. Match the holes in the brackets with the
holes on the rack, then secure the switch with the rack-mount screws.
Note: For proper ventilation, allow at least 4 inches (10 cm) of clearance to the front
and 3.4 inches (8 cm) at the back of the switch. We recommend this for an
enclosed rack installation.
When installed, connect the power cord to the power jack on the rear panel then to a power
outlet. The input voltage is 100-240VAC@50~60Hz. Check the power indicator on the front
panel to see if power is properly supplied.

Troubleshooting
Problem Suggested action
System LED does not light
up after the switch is turned
on.
Verify if the power cord is securely connected to the switch
and to a power strip.
Link LED does not light up
after an Ethernet cable is
attached.
1. Look for loose or faulty connections, make sure the
connections are secure. If these could not solve the
problem, try another cable.
2. Check the network cable used. Non-standard and
miswired cables can cause collisions and can seriously
impair network performance. Use of a category 5 cable
tester is recommended.
3. Check your network topology. Make sure that you have a
valid network topology. Common topology faults include
overlong cable and too many repeaters (hubs) between
end nodes. Also make sure that the network topology
contains no loops (i.e., only one active path is allowed
between every two nodes at any time). Loops can cause
broadcast storms and severely reduce your network
performance.
