Management Panel of ACX7100-32C Routers
The management panel of ACX7100-32C routers is located on the front of the router along with the interface ports. Figure 1 shows the management panel components on an ACX7100-32C router.

1 — Management (MGMT) port | 4 — USB port |
2 — 1-PPS and 10-MHz GPS input and output ports | 5 — Status LEDs |
3 — RESET button | 6 — Console (CON) port. An optional
GPS time of day (TOD) device is also supported. To connect to both
a console and a TOD device simultaneously, you must use the breakout
cable that is provided with the device. |
The management panel on an ACX7100-32C router displays the router product number, and consists of the following components:
Status LEDs—ALM, SYS, MST, and ID LEDs.
Management (MGMT) port—10/100/1000BASE-T management port that uses an RJ-45 connector to connect to a management device for out-of-band management. See Connect an ACX7100-32C Router to a Network for Out-of-Band Management.
Console (CON) port—uses an RJ-45 connector to connect to a console management device. An optional GPS time of day (TOD) device is also supported. To connect to both a console and a TOD device simultaneously, you must use the breakout cable that is provided with the device.
Note:If you connect to both console and ToD simultaneously using a breakout cable, you must ensure that you have not configured the

hierarchy level.USB port for image updates
Reset button to reset the device.
SMB connector ports that support 1-PPS and 10-MHz timing devices.
Management Port LEDs on ACX7100-32C Routers
The ACX7100-32C has one management port that has separate LEDs to indicate link status and link activity. The port is located on the management panel and is labeled MGMT. Figure 2 shows the location of the LEDs.

1 — Link activity LED (RJ-45) | 2 — Status LED (RJ-45) |
Table 1 describes the management port LEDs on ACX7100-32C routers.

Port Panel of ACX7100-32C Routers
The port panel of an ACX7100-32C router has the following port configurations:
Thirty-two quad small form-factor pluggable (QSFP28) transceivers (ports 0 through 31) that operate at 100-Gbps speed when you use QSFP28 transceivers or at 40-Gbps speed when you use QSFP+ transceivers.
Note:You can configure port 31 as a 1-Gigabit SFP grandmaster port by using a QSA adapter to convert the QSFP28 port to a 1-Gigabit SFP port.
Four double density quad small-form factor pluggable (QSFP56-DD) ports (ports 32 through 35) that are configured as 400GbE ports by default.
The QSFP56-DD network ports support:
QSFP56-DD transceivers
QSFP28-DD transceivers
QSFP28 transceivers
QSFP+ transceivers
Active optical cables (AOC)
Direct attach copper (DAC) cables
Figure 3 shows the port panel on an ACX7100-32C router.

1 — 100GbE ports (32 QSFP28 ports) | 2 — 400GbE ports (4 QSFP56-DD ports) |
Network Port LEDs on ACX7100-32C Routers
Each ACX7100-32C network port uses a single bicolored LED to indicate link status, activity on the link, or a fault condition. Figure 4 and Figure 5 show the location of the LEDs on an ACX7100-32C device.

1 — Left port LED | 2 — Right port LED |

1 — Upper port LED | 2 — Lower port LED |
The number next to the LED indicates the port number to which the LED belongs. All network port LEDs behave the same. Table 2 describes the network port LEDs on ACX7100-32C routers, their colors and states, and the status that they indicate.
LED Color |
LED State |
Description |
---|---|---|
Unlit |
Off |
The port is administratively disabled, there is no power, the link is down, or a transceiver is not present. |
Green |
On steadily |
A link is established, and all channels are up. |
Blinking |
The beacon function is enabled on the port. |
|
Amber |

Chassis Status LEDs on ACX7100-32C Routers
The ACX7100-32C routers have four status LEDs that indicate the system status. You can find these LEDs to the right of the network ports (see Figure 6).

1 — ALM (Alarm) | 3 — MST (Primary) |
2 — SYS (System) | 4 — ID (Identification) |
Table 3 describes
the chassis status LEDs on ACX7100-32C routers, their colors and states,
and the status that they indicate. You can view the colors of the
three LEDs remotely through the CLI by issuing the operational mode
command show chassis led
