VSP 4450 Series

The following diagrams illustrate the components on the front panels of the VSP 4450 Series switches. Ethernet ports 1-50 on the switch are considered to be in slot 1.

Note

VSP 4450 Series supports 100BASE-FX transceivers (AA14019074-E6) on the VSP 4450GSX model in SFP ports only. This model does not support 100BASE-FX in SFP+ ports.

VSP 4450GSX-PWR+

USB port.
Switch LEDs for system power (PWR), switch status (Status), and redundant power supply (RPS).
12 10/100/1000 Mbps RJ-45 ports with PoE+. LEDs indicating port activity are above the ports.
36 100/1000 Mbps SFP ports.
Two 1/10G SFP+ ports.
Console Port.

VSP 4450GTX-HT-PWR+

USB port but without a USB or a USB device cover.

Note

The VSP 4450GTX-HT-PWR+ model does not require a USB device in the USB port for normal operation. The USB port can be used for additional storage using a USB memory stick.
Switch LEDs for system power (PWR), switch status (Status), and redundant power supply (RPS).
48 10/100/1000 Mbps RJ-45 ports with 802.3at PoE+. LEDs indicating port activity are above the ports.
Two combo port SFP slots. Supports 1G SFPs and 100Base low speed SFPs.
Two SFP+ slots. Supports 1G SFPs and 10G SFP+s.
Console Port.
Field-replaceable 1000W AC power supply unit (PSU).
Second field-replaceable AC power supply unit for redundancy or additional PoE.

VSP 4450GSX-DC

USB port.
Switch LEDs for system power (PWR), switch status (Status), and redundant power supply (RPS).
12 10/100/1000 Mbps RJ-45 ports. LEDs indicating port activity are above the ports.
36 100/1000 Mbps SPF ports.
Two SFP+ slots. Supports 1G SFPs and 10G SFP+s.
Console Port.

Notes on Combination Ports

When the VSP 4450 Series is reset, the peer connections for all ports, including combination ports 47 and 48 on VSP 4450GTX-HT-PWR+, will transition down. During the reset, the fiber ports remain down, but only the copper ports 47 and 48 come up periodically throughout the reset. The copper ports 47 and 48 come up approximately 15 seconds into the reset, remain up for approximately 60 seconds, and then transition down until the boot sequence is complete and all ports come back up.

The following is an example of the status of the combination ports during reset.

CP1 [03/18/70 09:55:35.890] 0x0000c5e7 00300001.238 DYNAMIC SET GlobalRouter HW INFO Link Down(1/47)

Cabled Connections for Both Copper and Fiber Ports

The following limitations apply when the combination ports have cabled connections for both the copper and fiber ports.

Do not use the fiber port and do not insert an SFP into the optical module slot in the following situations:

a copper speed setting of either 10M or 100M is required
a copper duplex setting of half-duplex is required

Note

These limitations apply only when Auto-Negotiation is disabled. To avoid this limitation, use Auto-Negotiation to determine the speed to 10/100/1000 and to determine the duplex.

The 100M-FX SFP requires Auto-Negotiation to be disabled. Therefore, Auto-Negotiation will also be disabled for the copper port. Configure the peer switch to disable Auto-Negotiation.
