The line cards are hot swappable into and out of the system. Each line card can only be used in its dedicated slot.
Each AT-LX3811/x line card contains one SFP transceiver slot.
To install an AT-LX3811/x line card, refer to “Installing an AT-LX3811/x Line Card” on page 50.

Chapter 1: Overview

AT-LX3801 Blank Slot Covers

The AT-LX3800U chassis is shipped with eight AT-LX3801 Blank Slot Covers in place. The blank slot cover protects the fiber optic connectors on the backplane from becoming dirty, and helps maintain proper air flow through the chassis. A blank slot cover is shown in Figure 5.

Allied Telesyn strongly recommends that a blank slot cover be inserted in any slot that does not contain a functioning line card.
To install a blank slot cover that was removed from the chassis, refer to “Installing an AT-LX3801 Blank Slot Cover” on page 55.

LEDs

The AT-LX3800U provides two groups of LEDs, one group for each line card and one group for the system.

Line Card LEDs Each line card has six LEDs, as shown in Figure 6.

Figure 6. Line Card LEDs
The line card LEDs include a RDY (Ready) LED that provides information about the overall operation of the line card, and two groups marked TRIB and LINE. The TRIB LEDs provide information about the tributary side of the line card (the operation of the SFP), and the LINE LEDs display information about the line side of the line card (the operation of the RX and TX Wavelength Division Multiplexing (WDM) ports).
124
The LEDs are described in the following tables:
The RDY LED is described in Table 2.The tributary side TX and RX LEDs are described in Table 3 on
page 24.
The line side TX and RX LEDs are described in Table 4 on page 25.The line side Sync LED is described in Table 5 on page 27.
Table 2 describes the RDY LED on the tributary side.
Table 2. RDY LED
State Description
Flashing green Power is on, but the card is in the wrong slot.
Note that when a new version of the AT-S65 management software is being downloaded, the RDY LED may flash on all line cards until the downloading is complete.
Solid green Power is on and the card is in the correct slot.
Off The line card is not receiving any power.
23
Chapter 1: Overview
Note
When you install or reinstall a line card, the AT-S65 management software recognizes this change within 20 seconds.
The operation of the tributary side TX and RX LEDs is affected by the status of the Missing Link feature in the AT-S65 management software. Table 3 describes the TX and RX LEDs on the tributary side.

AT-LXPWR Power Supply Module

The AT-LX3800U chassis is shipped with one AT-LXPWR power supply preinstalled in slot A, and one empty slot (B) for an optional redundant power supply (RPS). Two power supply versions, AC and DC, are available for the AT-LX3800U chassis, as described below. Both slots support any combination of AC and DC power supplies.
When two power supplies are installed, one of them works in standby mode while the other one provides full power to the chassis. If one power supply fails, the remaining power supply provides all the power to the system, preventing a system failure.
