Note

Keep the exhaust air vents clear of any obstructions to insure proper
cooling of the switch components.

 SFP+ Slots - There are 48 SPF+ slots (ports 1 - 48) on the rear

panel. Each port supports communication speeds up to 10Gbps.
The switch supports a variety of 10G SFP+ transceivers and direct
attach cables.

The AT-DC2552XS L2 Data Center Switch only supports SFP+
transceivers in this product. Refer to “Installing SFP+ Transceivers
and Cables” on page 56 for installation instructions of the SFP+
transceivers.

Each SFP+ slot has a dust cover installed at the factory which
should be left in place until a SFP+ transceiver is installed.

 SFP+ Slot LEDs - Each SFP+ slot has a corresponding LED which

displays the link and activity status of the port. Refer to Figure 3 on
page 23 for the location of these LEDs and Table 2 on page 23 for
their functional description.

 QSFP+ Slots - There are four QSFP+ slots which support

communication speeds up to 40 GB. These slots are numbered 49,
53, 57 and 61. Each slot may be configured as one 40 GB port or 4
X 10GB ports in the management software. Refer to Figure 4 on
page 24 for the location of these LEDs and Table 3 on page 24 for
their functional description. Refer to “Installing QSFP+
Transceivers and Cables” on page 61 for installation instructions.

Each QSFP+ slot has a dust cover installed at the factory which
should be left in place until an QSFP+ transceiver is installed.

QSFP+ transceivers must be purchased separately. For more
information about the list of supported QSFP+ transceivers, refer to
“Optional SFP+ Transceivers” on page 17.

 QSFP+ Slot LEDs - Each QSFP+ slot has a corresponding QSFP+

LED which displays the link and activity status of the QSFP + slots.
Refer to “QSFP+ Slot LEDs” on page 24 for the functional
description.

 Power/Fault LED - The Status LED displays the overall status of

the chassis, power supply modules and fan modules. Refer to

Chapter 1: Overview

Note

“Power/Fault LED” on page 25 for the functional description.

 Console Port - The console port is a standard RS-232 interface

using an USB interface. This port provides the capability to
manage the configuration and firmware of the switch locally
independent from the Ethernet network. Refer to “Connecting the
Console Port” on page 70 for more information.

An RS-232 cable (female USB / D-Sub 9 pin) cable is included with
the AT-DC2552XS shipping container.

 NET MGMT Port - This 10/100/1000BASE-T RJ-45 Ethernet port

provides the capability to manage the configuration and firmware
of the switch. You can obtain or forward information via the CLI or
SNMP interface. The port features auto MDI/MDI-X and auto
negotiation.

The cable requirements of the NET MGMT port are given in
Table 1.

 NET MGMT Port LEDs - These two LEDs display the speed, link

and activity status of the NET MGMT Port. Refer to “NET MGMT
